    - Ctrl-c / Ctrl-v doesn't work on no touch deployment Hi, I have a client application that is deployed using the "no touch deployment". For some reason, the copy/paste shortcut keys (ctrl-c/v) doesn't work on the winform running in the IEHost. Is there a solution that enables the copy/paste shortcuts? Thanks, Hagay.

    - Simple question on menuitem I have a menu with menuitem "Delete". I want to reuse the functionality of the DELETE key on the keyboard. How can I do this in a menuitem? What does the VB code look like? I would like to create menuitems for copy and paste as well (reuse windows functionality ctrl+C and ctrl+V??), and have no idea on how to reuse. Please point me in the right direction. Regards Tore Tag: Application Freezes Tag: 64291

    - BUG: ComboBox.OnSelectedItemChanged I found the following bug: When manualy selecting a new item from a ComboBox the OnSelectedItemChanged is not called. When settings SelectedItem or SelectedIndex from code, it is correctly called. A small test program to duplicate the bug follows: using System; using System.Collections; using System.ComponentModel; using System.Diagnostics; using System.Drawing; using System.Windows.Forms; namespace BugTester { public class BugForm : System.Windows.Forms.Form { private TestComboBox comboBox1; /// <summary> /// Required designer variable. /// </summary> private System.ComponentModel.Container components = null; public BugForm() { // // Required for Windows Form Designer support // InitializeComponent(); } /// <summary> /// Clean up any resources being used. /// </summary> protected override void Dispose( bool disposing ) { if( disposing ) { if (components != null) { components.Dispose(); } } base.Dispose( disposing ); } #region Windows Form Designer generated code /// <summary> /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// </summary> private void InitializeComponent() { this.comboBox1 = new BugTester.TestComboBox(); this.SuspendLayout(); // // comboBox1 // this.comboBox1.DropDownStyle = System.Windows.Forms.ComboBoxStyle.DropDownList; this.comboBox1.Items.AddRange(new object[] { "Item 1", "Item 2", "Item 3"}); this.comboBox1.Location = new System.Drawing.Point(8, 8); this.comboBox1.Name = "comboBox1"; this.comboBox1.Size = new System.Drawing.Size(280, 21); this.comboBox1.TabIndex = 0; // // BugForm // this.AutoScaleBaseSize = new System.Drawing.Size(5, 13); this.ClientSize = new System.Drawing.Size(292, 38); this.Controls.Add(this.comboBox1); this.Name = "BugForm"; this.Text = "Form1"; this.ResumeLayout(false); } #endregion protected override void OnLoad( EventArgs e ) { Debug.WriteLine( "Setting Selected Index" ); comboBox1.SelectedIndex = 1; Debug.WriteLine( "Setting Selected Item" ); comboBox1.SelectedItem = comboBox1.Items[2]; Debug.WriteLine( "Now selected an item manualy" ); base.OnLoad( e ); } [STAThread] static void Main() { Application.Run( new BugForm() ); } } public class TestComboBox : ComboBox { protected override void OnSelectedIndexChanged( EventArgs e ) { Debug.WriteLine( "OnSelectedIndexChanged called" ); base.OnSelectedIndexChanged( e ); } // this method is not called when manualy selecting a new item in the combobox protected override void OnSelectedItemChanged(EventArgs e) { Debug.WriteLine( "OnSelectedItemChanged called" ); base.OnSelectedItemChanged( e ); } } } Tag: Application Freezes Tag: 64281

    - PropertyGrid using DefaultValue attribute - MUST IT ?? Is there ANY way you can persuade a property grid control to use something else for each property's default value, and not the DefaultValue attribute (attributes as far as I can see are read-only - is this right?). I want to base a PropertyGrid control on a single class but to have the default values for each property different for each instance of the class. CAN THIS BE DONE ??

    - quick money To: everyone Topic: a way to make money quick easy and legally=20 HOW TO TURN $6 into $6,000 !!!!!! Remember: play FAIRLY=20 and HONESTLY and this will really work. I found this on a=20 bulletin board and decided to try it. A little while back,=20 I was browsing through newsgroups, just like you are now,=20 and came across an article similar to this that said you=20 could make thousands of dollars within weeks with only an=20 initial investment of $6.00! So I thought, Yeah right,=20 this must be a scam,but like most of us, I was curious, so=20 I kept reading. Anyway, it said that you send $1.00 to=20 each of the 6 names and address stated in the article. You=20 then place your own name and address in the bottom of the=20 list at #6, and post the article in at least 200=20 newsgroups. (There are thousands) No catch, that was it.=20 So after thinking it over, and talking to a few people=20 first, I thought about trying it. I figured: what have I=20 got to lose except 6 stamps and $6.00, right? Then I=20 invested the measly $6.00. Well GUESS WHAT!!... within 7=20 days, I started getting money in the mail! I was shocked!=20 I figured it would end soon, but the money just kept=20 coming in. In my first week, I made about $25.00. By the=20 end of the second week I had made a total of over=20 $1,000.00! In the third week I had over $10,000.00 and=20 it's still growing. This is now my fourth week and I have=20 made a total of just over $42,000.00 and it's still coming=20 in rapidly. It's certainly worth $6.00, and 6 stamps, I=20 have spent more than that on the lottery!! Let me tell you=20 how this works and most importantly, why it works....Also,=20 make sure you print a copy of this article NOW, so you can=20 get the information off of it as you need it. I promise=20 you that if you follow the directions exactly, that you=20 will start making more money than you thought possible by=20 doing something so easy! Suggestion: Read this entire=20 message carefully! (print it out or download it.) Follow=20 the simple directions and watch the money come in! It's=20 easy. It's legal. And, your investment is only $6.00 (Plus=20 postage) IMPORTANT: This is not a rip-off; it is not=20 indecent; it is not illegal; and it is virtually no risk -=20 it really works!!!! If all of the following instructions=20 are adhered to, you will receive extraordinary dividends.=20 PLEASE NOTE: Please follow these directions EXACTLY, and=20 $50,000 or more can be yours in 20 to 60 days. This=20 program remains successful because of the honesty and=20 integrity of the participants. Please continue its success=20 by carefully adhering to the instructions. You will now=20 become part of the Mail Order business. In this business=20 your product is not solid and tangible, it's a service.=20 You are in the business of developing Mailing Lists. Many=20 large corporations are happy to pay big bucks for quality=20 lists. However, the money made from the mailing lists is=20 secondary to the income which is made from people like you=20 and me asking to be included in that list. Here are the 4=20 easy steps to success: STEP 1: Get 6 separate pieces of=20 paper and write the following on each piece of=20 paper;PLEASE PUT ME ON YOUR MAILING LIST. Now get 6 US=20 $1.00 bills and place ONE inside EACH of the 6 pieces of=20 paper so the bill will not be seen through the envelope=20 (to prevent thievery). Next, place one paper in each of=20 the 6 envelopes and seal them. You should now have 6=20 sealed envelopes, each with a piece of paper stating the=20 above phrase, your name and address, and a $1.00 bill.=20 What you are doing is creating a service. THIS IS=20 ABSOLUTELY LEGAL! You are requesting a legitimate service=20 and you are paying for it! Like most of us I was a little=20 skeptical and a little worried about the legal aspects of=20 it all. So I checked it out with the U.S. Post Office (1- 800-725-2161) and they confirmed that it is indeed legal!=20 Mail the 6 envelopes to the following addresses: #1) Jeff=20 Millan 1113 N. 19 =BD McAllen,TX 78501 #2) simon white 23=20 mason road stroud glostershire eng #3) Wayne Clark 146=20 Poningo St. Port Chester, NY 105 #4) T. brayford dotburn=20 park road stroud glos eng gl5 2jf #5) Alan Meyer 17725 W.=20 Belmont Ave. Kerman, CA 93630 #6) Joshua North 17415 W.=20 Whitesbridge Kerman, CA 93630 STEP 2: Now take the #1 name=20 off the list that you see above, move the other names up=20 (6 becomes 5, 5 becomes 4, etc...) and add YOUR Name as=20 number 6 on the list. STEP 3: Change anything you need to,=20 but try to keep this article as close to original as=20 possible. Now, post your amended article to at least 200=20 newsgroups. (I think there are close to 100,000 groups)=20 All you need is 200, but remember, the more you post, the=20 more money you make! This is perfectly legal! If you have=20 any doubts, refer to Title 18 Sec. 1302 & 1341 of the=20 Postal lottery laws. Keep a copy of these steps for=20 yourself and, whenever you need money, you can use it=20 again, and again. PLEASE REMEMBER that this program=20 remains successful because of the honesty and integrity of=20 the participants and by their carefully adhering to the=20 directions. Look at it this way. If you are of integrity,=20 the program will continue and the money that so many=20 others have received will come your way. NOTE: You may=20 want to retain every name and address sent to you, either=20 on a computer or hard copy and keep the notes people send=20 you. This VERIFIES that you are truly providing a service.=20 (Also, it might be a good idea to wrap the $1 in dark=20 paper to reduce the risk of mail theft.) So, as each post=20 is downloaded and the directions carefully followed, six=20 members will be reimbursed for their participation as a=20 List Developer with one dollar each. Your name will move=20 up the list geometrically so that when your name reaches=20 the #1 position you will be receiving thousands of dollars=20 in CASH!!! What an opportunity for only$6.00 ($1.00 for=20 each of the first six people listed above) Send it now,=20 add your own name to the list and you're in business! --- DIRECTIONS ----- FOR HOW TO POST TO NEWSGROUPS------------=20 Step 1) You do not need to re-type this entire letter to=20 do your own posting. Simply put your cursor at the=20 beginning of this letter and drag your cursor to the=20 bottom of this document, and select 'copy' from the edit=20 menu. This will copy the entire letter into the computer's=20 memory. Step 2) Open a blank 'notepad' file and place your=20 cursor at the top of the blank page. From the 'edit' menu=20 select 'paste'. This will paste a copy of the letter into=20 notepad so that you can add your name to the list. Step 3)=20 Save your new notepad file as a .txt file. If you want to=20 do your postings in different settings, you'll always have=20 this file to go back to. Step 4) Use Netscape or Internet=20 explorer and try searching for various newsgroups (on-line=20 forums, message boards, chat sites, discussions.) Step 5)=20 Visit these message boards and post this article as a new=20 message by highlighting the text of this letter and=20 selecting paste from the edit menu. Fill in the Subject,=20 this will be the header that everyone sees as they scroll=20 through the list of postings in a particular group, click=20 the post message button. You're done with your first one!=20 Congratulations...THAT'S IT! All you have to do is jump to=20 different newsgroups and post away, after you get the hang=20 of it, it will take about 30 seconds for each newsgroup!=20 **REMEMBER, THE MORE NEWSGROUPS YOU POST IN, THE MORE=20 MONEY YOU WILL MAKE!! BUT YOU HAVE TO POST A MINIMUM OF=20 200** That's it! You will begin receiving money from=20 around the world within days! You may eventually want to=20 rent a P.O.Box due to the large amount of mail you will=20 receive. If you wish to stay anonymous, you can invent a=20 name to use, as long as the postman will deliver it.=20 **JUST MAKE SURE ALL THE ADDRESSES ARE CORRECT.** Now the=20 WHY part: Out of 200 postings, say I receive only 5=20 replies (a very low example). So then I made $5.00 with my=20 name at #6 on the letter. Now, each of the 5 persons who=20 just sent me $1.00 make the MINIMUM 200 postings, each=20 with my name at #5 and only 5 persons respond to each of=20 the original 5, that is another $25.00 for me, now those=20 25 each make 200 MINIMUM posts with my name at #4 and only=20 5 replies each, I will bring in an additional $125.00!=20 Now, those 125 persons turn around and post the MINIMUM=20 200 with my name at #3 and only receive 5 replies each, I=20 will make an additional $626.00! OK, now here is the fun=20 part, each of those 625 persons post a MINIMUM 200 letters=20 with my name at #2 and they each only receive 5 replies,=20 that just made me $3,125.00!!! Those 3,125 persons will=20 all deliver this message to 200 newsgroups with my name at=20 #1 and if still 5 persons per 200 newsgroups react I will=20 receive $15,625,00! With an original investment of only=20 $6.00! AMAZING! When your name is no longer on the list,=20 you just take the latest posting in the newsgroups, and=20 send out another $6.00 to names on the list, putting your=20 name at number 6 again. And start posting again. The thing=20 to remember is: do you realize that thousands of people=20 all over the world are joining the internet and reading=20 these articles everyday?, JUST LIKE YOU are now!! So, can=20 you afford $6.00 and see if it really works?? I think=20 so... People have said, "e;what if the plan is played out=20 and no one sends you the money? So what! What are the=20 chances of that happening when there are tons of new=20 honest users and new honest people who are joining the=20 internet and newsgroups everyday and are willing to give=20 it a try? Estimates are at 20,000 to 50,000 new users,=20 every day, with thousands of those joining the actual=20 internet. Remember: play FAIRLY and HONESTLY and this will=20 really work.=20 =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= BE AN=20 INTERNET MILLIONAIRE LIKE OTHERS WITHIN A YEAR!!!

    - Looking for an equivalent in .NET framework / WindowsForms Hello, I come from the Delphi world which has what is called a TActionList. In a nutshell, an action list is a way to centralize the response to user commands (actions). Action list components maintain a list of actions that are available to the client controls in an application. These actions also hold the images related to the actions. I place my relavent code in the action and just assign that action to the action property on the control (button, menu, popup menu, etc.). I can then control the action which will in turn affect all controls that have that action assigned to them. For example, I can disable an action and the menu, toolbar, and popup menu all reflect that disabled state. Is there anything in WindowsForms or, at a lower level, the .NET frameworld that works similarly? Thanks for you input. Tag: Application Freezes Tag: 64261

    - What's the point of Simple Data Binding? Hello All, In two different books, Simple Data Binding to a control is explained with an example of a TextBox where the data is initialized with an array. For example a class is defined as such: public class Vendor { private string vendorName; public string VendorName { get { return vendorName; } set { vendorName = value; } } public Vendor(string strVendorName) { VendorName = strVendorName; } } } A TextBox is placed on the main form Form1 with the following code: public Vendor[] aVendors; private void Form1_Load(object sender, System.EventArgs e) { this.aVendors = new Vendor[3]; aVendors[0] = new Vendor("Microsoft"); aVendors[1] = new Vendor("Praxis"); aVendors[2] = new Vendor("Rational"); txtVendor.DataBindings.Add("Text",aVendors,"VendorName"); } where txtVendor is the name of the TextBox. My question now is what else can you do with this? What's the point? Is there some utilitarian advantage here that I am not seeing? Neither of the texts expands on this. They both go into Complex Data Binding which is a different animal. FYI,I am coming from the MFC VC++ world is that means anything.

    - DataGrid DataMember changes Hello, I have a DataSet of multiple related tables that I display in a DataGrid. When the user drills down to a child table, or when he "drills back up" to the parent table, I want to populate a ComboBox with the names of the columns in the currently-displayed table. I've done some playing around with a currency manager for the DataMember of the grid, but it doesn't really give me what I want. Any suggestions for how to attack this? I'm stumped. The problem is with finding out when the user has changed the table he is viewing (and determining what the new table is). I can handle getting the info into the combobox.

    - Custom Control Properties in WinRes Hopefully someone out there can answer this question. It seems like a basic problem, but I can't figure out what's wrong. I have a form with a custom control that I want someone else to localize with WinRes. When you load the .resx file with WinRes, and the custom control assembly is in a place that WinRes can find it, it displays all the controls properly, including the custom control, but not all of the properties are available for editing in WinRes. Is there something I'm missing? I have source for the control - do I need to add something to the control so that WinRes can display the properties of the control? Thanks!

    - Avoiding focus I am trying to create a virtual keypad control for my client's touch screen application (using Windows XP). I have created a form, which I call Keypad, and in CreateParameters have added WS_EX_NOACTIVATE to the CreateParameter's ExStyle. This is supposed to tell the form to not take focus. I put a label on the form and hook into the Click event. I start my main application form, which has a text box control on it. I open my Keypad form, then select some text in the main application's text box. When I click on the label, the Keypad grabs focus and the selection in my applications text box loses focus. I've tried several things, but can't get the Keypad form to avoid grabbing focus. Can someone tell me what I am missing here? Tag: Application Freezes Tag: 64233

    - Localization and winres Hi, I just ran into the localization utility "winres.exe". This is a pretty handy little thing for translators, but one thing puzzled me: Lets say I have a form with a single button on it. Caption is "button1". Translator translates and I get the new resource file. So fra so good. Now I decide that my form needs another button for v2 of my application. Then what? If I send the translator the same default resource file, he would have to start all over (not that big a deal with two buttons, but what if there were 27 buttons and just as many labels).

    - MouseUp event is raised when I double click my MDI form caption bar Hi everybody: I have a MDI application which has MDI forms containing every form a list view that shows files and folders like Windows Explorer. I have my own implementation of the context menu, so, I programatically show it when the mouseUp event is raised over the list view and the mouse button is the right button (quite obvious). My problem occurs when I show the context menu, and after I maximize the MDI form double-clicking the caption bar: My context menu is shown again because the mouse up of the list view is raised!!!! I searched in this group and I did not found similar problems and I have no idea to solve this problem because the MouseEventArgs object that my OnMouseUp() method receives is valid.

    - Visible = False on Form_Closing... Hi, I have a MDIForm with some MDIChilds. When the user clicks on the "x" in the upper right corner, I don't want the MDIChild to be closed, but the property Visible = False. So far no problem: I do this useing the Form_Closing-event in which I typed: e.Cancel = True Me.Visibible = False But: When I Close the MDIParent, it wont shut down the whole application because of the fact that those MDIChilds cancel the closing! I tryed to put work with a boolean which is set to true when MDIParent is closed, and first evaluated in the MIDChild_Closing-event, but that doesn't work either, because of the fact that the Closing-event of the MDIChilds are fired before the Closing Event of the Parent... Anybody got any idea how to do this? Maybe with the Closed-event? This event comes after the Closing-event, but I can't find someting in ot to Cancel the closing of the form. I guess there must be a 'nicer' way to do this: Maybe by handling the click on the "x", and when it is clicked not to close etc etc...

    - HOW: Inherited forms and OnClick Armin wrote on the 1st of Jan as a reply to Lorne Smith "The designer creates the default procedure for events. Event procedures are usually not Public Overridable. IMO, you should not change the signature in the base class. If you want an overridable sub handling the Click, add an Overridable OnButtonClick procedure called in the event handler of the base class. In the derived class, override OnButtonClick". Question 1: Can anyone give an example (VB.NET if possible) on how to do that? I can't find any. Not even the MSDE example for OnClick is about OnClick. I've got a copule of books on Windows Forms (many of the good) and loads of online articles, the authors avoid going into inherited forms, which is a pity, since quite many questions in this discussion group seem to be about just that. Question 2: I'm successfully using override, but now I get confused: Lorne Smith writes: "when I put code in the sub, it was executed twice when I ran the form. Now I realised this is because both the base form and the inherited form are handling the event". WHY does both the base form and the inherited form execute the event? I thought override meant that the overriding method executes INSTEAD of the overridden, not that both are executed. Why would I use the override keyword if I want both to execute? But clearly Lorne is right in that both are executed. I've considered that an oddity, but it is by-design then. Kind Regards, Kenneth Bohman Tag: Application Freezes Tag: 64191

    - Help! Microsoft.Win32.SystemEvents.WindowThreadProc eating CPU I have a windows forms application that occasionally eats 100% of the hosts system's CPU indefintely. If I break execution and selectively freeze threads, the culprit seems to be the thread named ".NET System Events". That thread is in a tight loop within SystemEvents.WindowThreadProc. I don't understand the disassembly, but it appears to be stuck completely within that method as I step through it. As I understand it, that thread is responsible for calling events when system properties change. I have hooked none of these events in my code, and like I said the thread appears to be looping entirely within the WindowThreadProc method. This happens most often when coming back from a Fast User Switch in XP or resuming from a suspended/hibernated state. What is going on?? How can I work around this?

    - Bug in Windows Form Designer generated code (VS.NET 2003) Every time I make a change affecting a toolbar (e.g. adding or removing buttons), I loose the bitmap images at runtime. They are still displayed in the designer, but when the application runs, the toolbar appears blank with only separators visible. I determined that the problem is caused by the wrong location of the toolbar.Buttons.AddRange function in the auto-generated InitializeComponent function, which is placed before buttons are initialized. If I manually move the AddRange function call after the button initialization calls, it works fine, but the next time I make a change, I have to do it again. This is really irritating. Is this a known bug? Is there a fix for it? A better workaround? Thanks. Alek Tag: Application Freezes Tag: 64175

I tried to do this and it didn't work: [Child Form "Form2"] Event OK (ByVal item as Object) 'I cast it as Object simply because that's the type of a Listbox Item. Private Sub Button1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Raiseevent OK(Lisbox1.selecteditem) End Sub -------------------------------- [Parent Form "Form1"] Private Sub Form2_OK(ByVal item as Object) Handles Form2.OK Listbox.Items.add(item) End Sub the fresh new item on Form1's Listbox shows "System.Data.DataRowView" what's going on?!?!?!?! thanx for all previous replies! ignacio ---------------------------------------------------------------------------- ------ >Hi Ignacio, > I think it has something to do with not giving valuemember and displaymember > values (what values could I give? it's not bound) You can bind a ListBox (via DataSource) to *any* object that implements the IList interface. This includes Array or ArrayList. You just need to fill one of these with suitable objects with a property for the string to display and another for the data you need and set the DisplayMember and ValueMember properties of the ListBox.

    - How to (easily) change the width of a single column in a DataGrid [VB.NET] I've run into a few posts on this, some with answers pointing to FAQs (like http://www.syncfusion.com/faq/winforms/search/754.asp), but I figured I'd go ahead and share the code I'm using. Basically, you need to set up a for loop through every column in your dataset and create a default action rigging up a DataGridColumnStyle for each. Then look for the cols that need special treatment and knock yourself out. You might insert a "case else" below and move the mappingname and headertext there to have a mutually exclusive default handler. ' Assumes you've got... ' Public dsTime As DataSet ' Public grdTime as DataGrid Dim myGridTableStyle As DataGridTableStyle = New DataGridTableStyle Dim TextCol As DataGridColumnStyle Dim dcTemp As DataColumn myGridTableStyle.MappingName = Me.dsTime.Tables(0).TableName For Each dcTemp In Me.dsTime.Tables(0).Columns TextCol = New DataGridTextBoxColumn ' I want my "description" column to be wider than the rest ' Select Case is overkill for one col, but is an easy place ' to expand to catch other columns Select Case dcTemp.ColumnName case "description" TextCol.Width = 250 End Select ' Everything else gets added with defaults, though you ' need to provide a name for the column to show up in ' the DataGrid. ' Seems to keep the default validators and everything ' by simply doing the below TextCol.MappingName = dcTemp.ColumnName TextCol.HeaderText = dcTemp.ColumnName myGridTableStyle.GridColumnStyles.Add(TextCol) Next ' add formatted tablestyle to the datagrid Me.grdTime.TableStyles.Add(myGridTableStyle) ' bind the datagrid Me.grdTime.DataSource = Me.dsTime.Tables(0) Ha, and if you search Google for something with "single" in it, like, say, [datagrid "single column"], prepare for some Google Ads to eHarmony.com & gotoCupid.com (though we all know GOTOs are Bad Things), etc. Tag: Application Freezes Tag: 64156

    - Control Focus issues Hello, A form with 3 textboxes and a button and the code below : Private Sub TextBox2_Enter fred() end sub Private Sub fred() TextBox3.focus End Private Sub TextBox3_enter console.writeline("Entering") End Private Sub TextBox3_Leave console.writeline("Leaving") end Private Sub Button1_Click TextBox2.focus End The intent here is to start with the focus in TextBox1 (no events), click the button. The button changes focus to TextBox2. The Enter event calls a routine that also shifts focus, this time to TextBox3. I would expect the output to be: Entering Instead I am getting Entering Leaving Entering This seems wrong and is causing some issues. In practice, tabbing to 'TextBox2' takes the place of the button click, but the end result is the same, a Leave event at the "wrong" time. mklapp Tag: Application Freezes Tag: 64154

    - Combo box in DataGrid The MSDN tells it would be possible to create own DataGridColumnStyles and there also exists a DataGrisComboBox in Microsoft.ClrAdmin. It can be bound to the GridColumnStyles Collection but just shows a DataGridTextBox. Who already tried this successfully? Tag: Application Freezes Tag: 64153

Dear All,

I have upgraded and application I developed on VB6 which uses the
Mscomm1 component and reads from COM1 port data send, then sends these
records to a table in SQL 2000. I upgraded the application to VB.Net windows
form to use the try catch method of trapping errors, the form runs smoothly
but after about 10 minutes the form freezes without raising any error.

Any hints will be useful.

Thanks,
Yahya

Run it under the debugger, and when it freezes, force the debugger to break
("Break All"). Once you know where in your program it is stuck, you can
start to ty to find out why.
