    - Email and .NET Hello, I am trying to format an email and have a .net application open up Outlook or Outlook Express so that the user can simply click Send and have the formatted email send from their email account. I am currently doing this the following way: Dim sParams As String Dim TheTo, TheSubject, TheBody As String TheTo = txtEmail.Text TheSubject = "" TheBody = "" sParams = "mailto:" & TheTo sParams = sParams & "?subject=" & TheSubject sParams = sParams & "&body=" & TheBody System.Diagnostics.Process.Start(sParams) The problem this is that it creates a new instance of Outlook every time the event is fired to create the email. All I want is for a new email to appear and add the data that I want. After about 6 or 7 emails are created this way, Outlook freezes up and stops working. Any suggestions will be greatly appreciated, This is vb .net. Chuck Tag: How to get mouse event when using DesignSurface? Tag: 99730

    - Edit different data types in a DataGrid in the same column on different rows Hi All Hopefully someone out there can answer this. I have a data source that displays a set of property names and values (each name/value pair will be displayed on a different row). I want to be able to enable the data source to be edited through the grid, but each of the values on different rows may be a different data type. I know I can apply a column style to set a whole column to display a ComboBox for a selection, a DateTimePicker, etc., but I'd like to know if there's a way to apply the style on a row-by-row basis. In doing this I should be able to display all the property name/value rows and have a different edit mode control appear for the value in each row depending on its data type. I should not neglect to mention that the data type of the value column can be defined programatically, as it's also held in the data source to describe the type of data in the value column. Can anyone please advise if this is possible, or if you'd like more information to clarify the problem. Thanks in advance, Sam. Tag: How to get mouse event when using DesignSurface? Tag: 99728

    - clicking MDI child does not activate form... Clicking an mdi child form will not activate the form unless I click on the sizeable border or title/caption bar. Sometimes it works correctly and I can click anywhere on the underlying child form and it pops to the front. Other times, I can type in text boxes of the child for, drop down combox boxes, etc, while the child form remains behind other forms. Gotta love .NET, right? I have noticed countless other posts on this topic going back to 2001, but no resolution. Has anyone been able to track down the cause for this behavior?

    - studio deleted my resx file, and now it won't rebuild it properly! I'm using Visual Studio 2003. I have a C# Forms app with several forms. While working, Studio asked to check the .resx file of a particular form out of SourceSafe. It then completely erased the .resx file, leaving the form empty in the Designer. However, all the code is still in the .cs file! Most solutions I've found say to delete the offending .resx file, and Studio will rebuild it for you. Unfortunately, that's not happening here. I close the form, delete the file, and try to reopen the form, but it comes up with a blank form again. This is EXTREMELY frustrating. Does anybody know how to fix this?

    - CheckedListbox and CheckOnClick I am working with the CheckedListBox and trying to get it to perform functionality similar to the Windows Explorer Choose Details window. The one thing I can't get to work is with the clicking on the checkbox part to autocheck. I can set the CheckOnClick to true, but I don't want it to autocheck if I click on the text part. Only if I click on the checkbox part. Anybody have any ideas on this? Lance Tag: How to get mouse event when using DesignSurface? Tag: 99722

    - Multithreading in Form Hi All, I am new to C# thread programming. I got one issue. I appreciate if anybody can point what i am doing wrong here. I have created one C#.NET application (VS.NET 2003 and 1.1 Framework). It contains two forms. (Form1 and Form2) Form1 contains only one button. On click of this button two threads will be created. This thread will just display the Form2. Form2 contains only one ActiveX control(Created by me, Works fine in single thread app for last 3-4 years). When i excute this application, if i click on the Button on Form1, Threads are created and it shows the Form2 and ActiveX control. So far its fine. When i close the Forms created by the thread it crashes. When i use the Debuger it says "User Break Point Called" and Call Stack shows following : NTDLL! 7c901230() _CrtDbgReport(int 2, const char * 0x5f4d0cf0 THIS_FILE, int 374, const char * 0x00000000, const char * 0x00000000) line 353 AfxAssertFailedLine(const char * 0x5f4d0cf0 THIS_FILE, int 374) line 39 + 20 bytes AfxWndProc(HWND__ * 0x0141056a, unsigned int 8, unsigned int 16057944, long 0) line 374 + 21 bytes AfxWndProcDllStatic(HWND__ * 0x0141056a, unsigned int 8, unsigned int 16057944, long 0) line 57 + 21 bytes USER32! 77d48734() USER32! 77d48816() USER32! 77d4c63f() USER32! 77d4c665() SYSTEM.WINDOWS.FORMS! 7b823b1e() SYSTEM.WINDOWS.FORMS! 7b823a2b() SYSTEM.WINDOWS.FORMS! 7b896ca4() SYSTEM.WINDOWS.FORMS! 7b82291b() 0096453a() USER32! 77d48816() USER32! 77d4b4c0() USER32! 77d4b50c() NTDLL! 7c90eae3() USER32! 77d48734() USER32! 77d5418d() USER32! 77d53fd9() USER32! 77d5b82a() USER32! 77d54e28() USER32! 77d561b3() USER32! 77d6a92e() USER32! 77d6a294() USER32! 77d95fbb() USER32! 77d96060() USER32! 77d80577() USER32! 77d8052f() __crtMessageBoxA(const char * 0x032fb9c8, const char * 0x102579a0 `string', unsigned int 73746) line 65 CrtMessageWindow(int 2, const char * 0x5f4d0cf0 THIS_FILE, const char * 0x032fcafc, const char * 0x00000000, const char * 0x032feb20) line 520 + 22 bytes _CrtDbgReport(int 2, const char * 0x5f4d0cf0 THIS_FILE, int 969, const char * 0x00000000, const char * 0x00000000) line 419 + 76 bytes AfxAssertFailedLine(const char * 0x5f4d0cf0 THIS_FILE, int 969) line 39 + 20 bytes CWnd::DestroyWindow() line 969 + 21 bytes COleControl::OnFinalRelease() line 358 CCmdTarget::InternalRelease() line 223 CCmdTarget::ExternalRelease() line 234 COleControl::XQuickActivate::Release(COleControl::XQuickActivate * const 0x03356630) line 69 OLE32! 7750de71() OLE32! 7750dbd2() OLE32! 77554a4f() OLE32! 77554a30() OLE32! 77564daf() OLE32! 7750221e() OLE32! 77502171() OLE32! 774ff221() OLE32! 774fee88() OLE32! 775131f0() OLE32! 774fd141() OLE32! 774fd0e9() NTDLL! 7c9011a7() NTDLL! 7c919213() KERNEL32! 7c80cce7() KERNEL32! 7c80b511 My C#.Net app source code looks like this: /// <summary> /// The main entry point for the application. /// </summary> [STAThread] static void Main() { Application.Run(new Form1()); } void MyThreadFunction() { Form frm = new Form2(); //Show the Form which contains the SymFacX.

    - Setting combo box items property? I am building a user control that has a combo box (comboBoxMain) as a constutient control. The user control has an Items property, which will set the items of the combo box. I want the user control Items property to be browsable at design-time, so the user of the control can click the properties, enter a list of items in the String Collection Editor and have them appear in the combo box. Here's the code I'm using now: [Browsable(true)] [EditorBrowsable(EditorBrowsableState.Always)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)] [Editor("System.Windows.Forms.Design.StringCollectionEditor,System.Design", "System.Drawing.Design.UITypeEditor, System.Drawing")] [Description("The list of objects in the combo box")] public ComboBox.ObjectCollection Items { get { return comboBoxMain.Items; } set { comboBoxMain.Items = value; } } The Editor attribute brings up the String Collection Editor, but it isn't retrieving any items I place in the combo box. And nothing that I enter in the editor is making it back to the combo box. What do I need to do to complete the connection between the user control Items property and the combo box Items property? Thanks. -- David Veeneman Foresight Systems Tag: How to get mouse event when using DesignSurface? Tag: 99716

    - No touch deployment - internet cache full We have had a few instances in our organization that the user was unable to run a no-touch deployment exe from our intranet. Clearing their full internet cache corrected this problem. This happened in 2 scenarios: 1. When trying to run the no touch .exe over the intranet would do nothing. 2. When trying to run the .exe over the intranet the user would run their old cached copy of the application and not download the latest from the server. In both scenarios clearing their internet cache and launching the application again corrected this problem. I thought the idea with internet cache is First In, First Out... in thus... cache would be cleared to accomodate new temporary internet files. Is this correct or is there an issue with no-touch deployment in this regard. Has anyone else ran into this problem, and if so what solutions have you come up with. Remember we have a large organization and no touch deployment applications are being used by 100+ individuals. One way I know would be to write a login script to clear the internet cache... of course.. not every user will reboot their PC every night... and isn't ideal for other reasons. Thanks in advance...

    - ConfigurationManager app.config Dear Friends, I have been trying to get the following to work properly, but with little luck. I have created a class that inherits from ConfigurationSection. I then added a <configSections> ... <section name="test"> in a new app.config (which I added manually to my project). It seems to be able to read the app.config, but not write back to it. I seem to have a partial/temporary working config file that is created in the bin\debug directory called XXX.vshost.exe.config. It seems to temporarily store the proper values when I save the settings, but seeing that it is rebuilt dynamically everytime the application is run, I lose all settings. What gets to me is that the settings are not written to the app.config file. I get no errors when I execute .Save method. Just no info is written. Does anyone have an example in VB.NET or a guide/tutorial, etc... In essence, I want to use my ConfigurationSection derived class to be able to load and save a custom section in the app.config file as I have seen others do, but can't get it to work myself. Also, any help on how to properly set up an app.config file with the <configSections> etc... properties. Regards, Giovanni Tag: How to get mouse event when using DesignSurface? Tag: 99713

    - Data binding a ListBox to a List<T> I have 2 list boxes on the form. Each listbox is bound to a different List<T>. My goal is for the user to select an item in ListBox1, click a button, and have that item moved to ListBox2. The way I approached this was to have a populated List<T1> bound to ListBox1. I set the DataSource, DisplayMember, and ValueMember properties of ListBox1 and the items in the List<T1> were correctly shown in the listBox. I bound ListBox2 to List<T2>. Since List<T2> had nothing in it, ListBox2 correctly showed no items. I thought that if I removed an item from List<T1>, that ListBox1 would update to reflect that but it doesn't seem to work that way. Similarly, I thought that by inserting an item into List<T2>, that the ListBox2 would update to reflect the addition. It does not seem to work that way. How can I get the ListBoxes to update and show the current contents of their respective List<T> objects? Is there a way to "rebind" them?

    - deriving DataGridTextBoxColumn - behaviour on new rows Hello I have derived a class from DataGridTextBoxColumn and am getting some behaviour which I do not understand and I would like to know where I am going wrong. The problem is like this. I have a datagrid, lets say with four columns. Two columns have my derived style and two have the default DataGridTextBoxColumn. When you make changes to the datagrid there is a button to press to validate and then send the changes back to the database to be written. The problem comes when you click in the "new row" at the bottom of a datagrid (the blank row with the star in the header). If you click into and then straight off the default DataGridTextBoxColumn in the new row, the UI indicates that no new row has been created, and if you then save the changes, no new rows are added to the database. However when you click on and then away from the derived class, the UI performs in the same way - it appears as if there are no new rows added, but when you click save changes you get a new row written to the database - with all the row default values. This implies that the row was created in the underlying DataTable, but that fact was not reflected in the UI of the datagrid. For reasons that I shall not go into this is a big problem for my application. What I would really like to know is what I need to do to get my derived column style to behave in the same way in this situation as the DataGridTextBoxColumn. I.e. click on and away - the UI implies that no row has been created and that is in fact the case when writing changes to the database. Thanks in advance for any light that can be shed on this issue! I've been reading lots of articles on MSDN but none that I have found seems to cover this situation! Best Regards David Smith Tag: How to get mouse event when using DesignSurface? Tag: 99688

    - ClickOnce Install returns XML I have deployed an application with ClickOnce Publish wizard to a web site. But when I click web page Install button the web server just returns the content of the .application file as XML to the browser on my own client. I made a quick try on two other clients and it seems that they are capable to interpret the web page correct ..... it is really a strange issue. trying the following command line in cmd.exe: rundll32.exe dfshim.dll,ShOpenVerbApplication http://www.xxxx.com/ConfigurationTest/ConfigurationTest.application Note: replace "http://www.xxx.com/ConfigurationTest/ConfigurationTest.application" with your clickonce application's deploy manifest URL. With this we can determine if the client side's dfshim.dll works well with the *.application files. However, even with dfshim.dll information, it is still hard for us to troubleshoot out this issue. Maybe we need re-install the Win2000 machine... This works.... Ok, I think you may first download the *.application file to the local disk, then double click this application file to do a test. Once your file association is correct, it should display the clickonce checking dialog. This works... I think there is more of a problem here. I am getting the same results on windows xp pro machines. I tried it on 3 different machines. The only machine that is able to install the application from the publish.htm is windows 2003 server that the application was publish from. But not an any (at least the 4 i've tried) xp pro machine... Ideas? Tag: How to get mouse event when using DesignSurface? Tag: 99684

    - window size and position - FixedToolWindow Hi, I'm using C# in VS2003 with .Net Framework 1.1 sp1 installed. I have a tool window that is sized and positioned to cover a certain part of another window. On my desktop machine this works perfectly however when I run it on my laptop the window is neither the correct size or position. If I close it and open it again it is moved slightly dwon and to the right each time. The size seemingly has nothing to do with the size the window is set too, all the controls appear in the correct place and size though. So I thought I must be using a different version of the framework on both machines so I spent ages making sure everything was the same version and as far as I can tell they are. If I take the version compiled on the laptop and run it on the desktop it works so it would appear that it is something to do with versions rather than the code but I'm clueless. My window uses FixedToolWindow and I've noticed that even at design time on the laptop its not showing a short title bar like a tool window should have. Has anyone come across this before? Please help!! I'm so annoyed because I thought I'd do this project in C# because it would be quick and easy but now I'm left wondering why if I cant give my client something that works identically on different machines why I didnt just do it in C++. I'm sure I wouldnt be having this problem then! Regards Josh Tag: How to get mouse event when using DesignSurface? Tag: 99678

    - ClosingEventArgs 'Cancel' member already set to true by framework I'm having a difficult time trying to track this issue down. Hopefully, someone might be able to share some insight. I have a situation where a form is not closed when I explicitly call Close() on it. As part of trying to debug this problem, I overrode the "OnClosing" method (and OnFormClosing, too) and noticed that the 'Cancel' member of the ClosingEventArgs parameter is already set to true upon entering and before I explicitly forward the call to base.OnClosing(). If I force Cancel to be false, then the form will close without a problem. Does anyone have an idea why the framework is setting Cancel to true? It is difficult to reproduce the problem with a small example. What I can tell you is that the form in question is a TopLevel (and TopMost) form with the Owner property set to an MDI child. The TopLevel form has a splitter control that houses two child forms... however, I remove the splitter control from the form before I call Close() (the form then contains no child controls). This is the point where the form fails to close. Tag: How to get mouse event when using DesignSurface? Tag: 99657

What I mean is, XP allows the user to classify icons in the system tray as "Hide when inactive" (default), "Always Show" and "Always Hide". I would like my application to be set to "Always Show". Is that possible? Thanks, Doug Tag: How to get mouse event when using DesignSurface? Tag: 99652

    - Accessing a form being created Hello, I would like to know if it possible to receive an event or intercept a message so I can access every form I create in my application. I want to add some functionality to my forms, but I want to do it in runtime. Is it possible to be notified every time a new form is created and before it is shown, so I can access it, for example, to add one specific control to it or to subscribe an event? Thanks in advance for any help given. Regards, paulo Tag: How to get mouse event when using DesignSurface? Tag: 99650

    - Accesing form's components in design time Hi, I need to access all components of a winform (controls, and any other component which does not inherit from System.Windows.Forms.Control) both in design and run time. In design time I access the components and iterate through them using form's Component property, but in run time this property is null. I can access all the controls using form's Controls property, but I need to access also the other components such as ContextMenu, ToolTips... which are not Controls. How can I get this? Thanks in advance. Tag: How to get mouse event when using DesignSurface? Tag: 99635

    - Exception in InitializeComponent On my test run-time machine my application is generating a "... has encountered a problem and needs to close..." exception from WITHIN the InitializeComponent section of my main form. This is curious since if I do a full install on my development machine it runs without a problem. This has happened to be before and I traced it that time to a form control using a font which was not on the target machine (why can't it just use a default font in this case??), but I've double checked all fonts used this time, and all seems to be ok. So my question is in general: how can I find out where it's going down in cases such as this? The "report contents" generated by the exception seem to give me little clue.

    - mysterious resize behavior... I have developed a custom Control inheriting from System.Windows.Forms.Control It has some children control. Something really weird happen when I resize it, its children control move! Even though I have specified Anchor = AnchorStyle.None & Dock = DockStyle.None (and I checked with the debugger that they still equals to that). Any idea why it is so? I have setup a break point on an event handler of the move event to understand what's going on.

    - PLS HELP:Managing events Hi, I'm developing a usercontrol which has an event SelectedValueChanged. Below is the simple version of what i have: //------------------------------ class SelectedValueChangedArgs: EventArgs { object m_oValue; public SelectedValueChangedArgs(object oValue) { m_oValue = oValue; } public object Value {get{return m_oValue;}} } //-- public delegate SelectedValueChangedHandler(object sender, SelectedValueChangedArgs e); //-- public MyControl{ public SelectedValueChangedHandler SelectedValueChanged; } //----------------------------------- The problem is that i have to make sure that any event handler added to that event is added only once, so i should use it like this: SelectedValueChangedHandler h = new SelectedValueChangedHandler(SomehandlerFundction); myControl.SelectedValueChanged -= h; myControl.SelectedValueChanged += h; But the problem is that i can't control all 30 developers in the company and i ended up spending the whole weekend cleaning up after them (adding -= to make sure the handler is not added second time somewhere). So now i'm thinking of making the event protected and creating a function which will be adding a handler: // -------- CODE --------- class MyControl{ <...> public void AddSelectedValueChagedHandler(SelectedValueChangedHandler h) { SelectedValueChanged -= h; SelectedValueChanged +- h; } } ///----------------------- Is there a standard way/pattern to make my life easier here? :) I think i've seen somewhere that you can override -=/+- for an event or something like that. I still would like to go with event instead of a wrapper function as above. Any ideas/comments are HIGHLY APPRECIATED!!!

    - Forms 8 - 10x Slower to load on .NET 2.0 with X64 executable why? With "Any CPU" chosen my application is 8-10x slower loading/displaying forms the first time they are loaded than if I choose X86 as my target.

    - Merging menuitems : nobody knows the answers ??? hi, i've posted this message at the start of last weekend, maybe that's why I didn't receive any answer (I know there are better things to do than sit in front of a computer a whole weekend) that's why I'll post again now. ---> when adding items to a MenuStrip VS 2005 defines them as objects of type ToolStripmenuItem ??? I would expect MenuItems (as in VS 2003). (Why this change ?) Thing is, I would like to merge menuitems using the MergeMenu-method, but this method is nowwhere to be found in ToolStripmenuItem. So, how does one merge (toolstrip)menuitems in VS 2005 ? thanks Chris Tag: How to get mouse event when using DesignSurface? Tag: 99609

    - SuspendLayout and Multiple Controls I am looking at ways to reduce the visible delay in a form I have with many controls. I have two methods that loop across and either enable or disable all but two of the controls. I am using SuspendLayout and ResumeLayout at the form level, but so far I don't see any real improvement because of it. Is there a better way to handle disabling / enabling large volumes of controls? I wish I could buffer the form paint surface and have it render off screen, then just paint the one image after the controls have all completed their painting. Thoughts appreciated.

    - Code signing with PFX certificate Hello, I created a certificate to sign a NET WinForm control. The certificate was locally generate on a Win2K server, I also tried using a Win2003 server. When I assign the Assembly keyfile with the certificate file and compile the C# control I get a "bad version provider" error. As a additional information I have used the Win2K server to sign macros in the past with no problems at all. This seems to be related to NET framework 1.1. I looked up on msdn and couldn't find information about this error. I will appreciate help to resolve this. thank you Carlos Lozano Tag: How to get mouse event when using DesignSurface? Tag: 99603

Hi all,

When I use DesignSurface and DesignSurface Manager to build a Designer, I
only can use SelectionService's SelectionChange event to know which component
is selected. But I don't know how to get mouse click in the component.
Becuase I want to show a contextmenustrip in each component.

Thanks,
