    - Form transparency issues Recently I wanted to create a small little program that could sit= on the desktop and not block the desktop wallpaper=2E There are= two methods to accomplish this ( that I am aware of )=2E 1) create a solid color bmp as a background image and set the= transparency key to match its color 2) specify the form's background color with a matching= transparency key Now my issues with both methods, but first it should be known= that I have set the forms to have no border or title bar and= have implemented code that allows me to click-and-hold anywhere= ( with exceptions listed below ) on the form and move it=2E The= data actually displayed on the form is just text and one= rectangle, all drawn by me ( there are no controls on the form= itself )=2E 1) I have two issues with this method, although it is what I'm= prefering to use at the moment=2E The first seems to be the= discrepancy between how the program is handled when the= computer's Color Depth is 32bit or when it is less than 32bit (= 16bit )=2E When the color depth is 32bit then I am able to click= on the entire area the form inhabits ( even that which is= transparent ) and move it, but if the color depth is less than= 32bit ( 16bit ) then only the drawn text or rectangle outline (= since it has no fill ) can be clicked to drag the program= around=2E Clicking on the transparent areas just passes the click= through the form to whatever is below ( even when I know the= form has focus )=2E I'd like to be able, regardless of the= desktop's color depth, to click anywhere within the form area= and move the application=2E The second issue I have with this method occurs when I take my= executable and put it on another PC ( my PC is XP Pro, the other= PC is XP Home=2E=2E Both SP2 )=2E The problem is similar, but a= little different=2E When the 2nd PC's color depth is at 32bit,= the transparency does not work=2E The green/lime ( that's the= transparent color I'm using ) background shows=2E Needless to say= this is not acceptable=2E When I change the color depth to less= than 32bit ( 24bit this time ), the transparency actually works,= but I come across the same issue of clicks on the transparent= areas just passing through=2E 2) With this method I have not tried it on a 2nd PC yet ( I don't= have it available where I am atm )=2E Its basically the same= "issue" as mentioned above with color depth less than 32bit,= except it does it with a color depth of 32bit and 16bit=2E Clicks= on the transparent areas just pass right through=2E I'm tempted= to just go with this method and possibly make one area on the= form that is meant to be used to drag it around ( similar to the= idea of the box that appears to move tables in MS Word ), but= I'm hoping there's a solution I'm unaware of before I do that=2E Anyways, all of this brings up some interesting questions=2E -What does color depth have to do with transparency handling? -Does the version of XP ( Home or Pro ) handle transparency= differently? Probably some more questions also=2E Not sure if it matters, but I'm doing all of this in C#=2E So any ideas to get pass any of these issues?

    - Odd closing problem I have a base form with a Cancel button (btnCancel) and a simple msgbox routine. I would like to have a routine closing check to prevent loss of data. Dim i As Integer i = MsgBox("Exit?", MsgBoxStyle.YesNo + MsgBoxStyle.Question) If i = MsgBoxResult.Yes Then Me.DialogResult = DialogResult.Abort Me.Dispose() End If I have another form that inherits from the base form. In both parent and decendent the Cancel button property of the form is set to (None). The problem is this. Even given the above, even given that I've traced the code and can see that the Me.dispose call is NOT being made when I click No, the form still closes. Any suggestions as to what I might be overlooking? Tag: Problem with Z-ordering !!! Tag: 78900

    - strange problem with binding collection object to listbox control I have a business object with two public properties - "OrganizationID" and "OrganizationName". Pretty typical. We will call it Organization. And I have a collection object which is an arraylist that stores a collection of the business object described above. Let's call it Organizations I have a lstbox control. So I bind it Organizations to the listbox control. lstSelectedOrgs.DataSource = null; lstSelectedOrgs.ValueMember = "OrganizationID"; lstSelectedOrgs.DisplayMember = "OrganizationName"; lstSelectedOrgs.DataSource = Organizations; I initially populate the control. Then I have a way to remove an item. And then I bind it again. At some point, all of a sudden, what shows up in the list box looks like this. MyNameSpace.Organization Tag: Problem with Z-ordering !!!

    - scrolling a user control Hi, I have created a user control which I then add standard controls to prgramatically i.e. picture box, text box etc. I'm just wondering if it is possible to scroll to given position in the scrollable region? So lets say the control has a height of 300 pixels and the scrollable height is 1000 pixels then I'd like to be able to just make pixel 500 appear in the top left of the controls visible area. If this isn't possible what alternatives are there for scrolling a user control programatically. Many thanks in advance for any answers. Best Regards, Steve. Tag: Problem with Z-ordering !!!

    - Client side controls in IE not working as expected I am developing a windows forms user control that will be hosted within IE from a web page. For testing purposes and on the client machine, I changed the .NET Framework security policy to give full access for the site that has the control. After all this, IE shows the control fine without problems. The problem happens when the control is signed with public private keys pair, IE doesn't show the control but shows an empty box instead (like an image link is missing or something).. This is the HTML code i am using to host the control: <OBJECT id="HelloWorldControl1" height="500" width="500" classid="NetAppletCtrl.dll#NetAppletCtrl.HelloWorldControl" VIEWASTEXT> </OBJECT> Any comments why IE doens't show the control when it's signed. Do I have to specify the strong name? I tried a lot and couldn't figure out how.. Maybe it's a bug in IE!! Thanks, Tag: Problem with Z-ordering !!! Tag: 78851

    - mshtml and windows services I have an application that uses the Ax web browser object. When I call the IHTMLElement.click() method on an input button (<input type="submit"> or <input type="button">), the click fires appropriately, if I'm running it from a windows forms based application. However, when I run the EXACT same code under a windows service, either as a logged in user or as the local system account, the click fails to process. Clicking on other elements (like <a>) works. I've tried submitting the form directly, in cases where a submit occurs, but can't do that either. Both GET and POST actions fail. What am I doing wrong? Is there something that prohibits the onclick event from firing for buttons when running as a service? Am I missing something? Robert Tag: Problem with Z-ordering !!! Tag: 78849

    - How to show a modal dialog from a different thread Hi, I have the following classical situation; 1)A long operation needs to be done in my application( that has many windows ) 2)A progress dialog must be shown in a separate thread 3)The long operation continues in the program main thread. The problem is, from the second thread I call ShowDialog(), but this dialog will not be Modal!!! Obviously .net modal dialog will only work if all dialogs in the application are opened in same thread. in my scenario I can simply switch between two dialogs( the progress dialog and the backgroud dialog) How can I show a dialog that is modal to all other dialogs even if the application dialogs were opened in different threads?

    - ImageLists on localized forms Hi. When setting Form.Localizable = True in Visual Studio, any ImageList on the form is copied/serialized into the resources for each language. This behavior is really annoying, since I only want to have _one_ copy of the icons (the same icons for all languages). Right now I have to either manually update the icons for each language or remove the serialized ImageList from the resx files. Another problem is that the application is getting "bloated" because of the multiple copies of the same icons. Is there any way to avoid this behavior? I already have implemented a customized LocalizationFilter ( http://windowsforms.net/articles/localizationfilter.aspx ), but the Windows Forms designer seems to ignore it when checking if the ImageLists should be serialized.

    - background images sooo slow Hi all, I'm working on an application and want to use background images for forms and controls. Using the images itself is not a problem, but when I run my application it becomes really slow and my CPU usage goes up to 100% for a time... Is there a better way of setting background images? It's just 3 images I think, all pretty small, and I already created the objects for the images and set them to the controls at runtime so that it uses only 3 objects and not new instances for every control. But still... It can't be that hard just to show a couple of images...? Many thanks for your help... Andreas Tag: Problem with Z-ordering !!! Tag: 78810

    - Richtext SelectedText Selectionstart I have a very ODD situation. I have a RichTextBox and a button. In the button click event I have the following: me.richtextbox1.SelectedText="test" Assuming I start with "aaaabbbbcccc" in the richtext box and I place the caret between the a and b and hit the button. I get "aaaatestbbbbcccc" as expected. Then I click between the b and the c and hit the button I get: "testaaaatestbbbbcccc". I added some watches on richtextbox1.SelectionStart and find that the first time it is 5 as expected. But on the second button press it is zero! Also the SelectionLength is zero on the second press even if I set the cursor between the b and c and drag across the first three of the c's. This all occurs in my actual application, so I created a simple form with only these two elements and it works fine. So obviously something else is interfering with this operation in my real application. I am at a loss as to what! In the real app the richtextbox is bound to a dataset, but I can't see why that should cause this behavior. I don't see any other events firing that might somehow screw up the SelectionStart like this. The Richtextbox is on a tabpage (and so is the button), but again I see no reason why that should have an effect. Anybody else ever struggle with this? Gary Tag: Problem with Z-ordering !!!

    - simple binding of controls to object properties - refresh controls I have a dialog with controls bound to class properties, e.g. : numericUpDownPort.DataBindings.Add("Value", localOptions, "Port"); textBoxDatabaseName.DataBindings.Add("Text", localOptions, "DatabaseName"); textBoxDataUsername.DataBindings.Add("Text", localOptions, "DataUsername"); - i.e. localOptions (a member of the form) is a instance of a class with properties DatabaseName, Port etc. My problem is that when the underlying object is refreshed (user can load the class from a file), the controls don't update. The object's properties are now different from the user interface. How to I force the controls to reload their data from the object?

    - ComboBoxes and the sorted property Discovered a fun one that I thought I should share, and hopefully catch Microsoft's attention to update some documentation. I'm a bit new to VB.NET, and was struggling with getting a combo box to work. I was attempting to take advantage of the cool way to load a combo box via a datasource, rather than the old VB6 way of adding selections. First I tried an array of objects. I had some issues with that that I suspect had a lot to do with not overloading ToString on the class so the combo box would return the right thing for the displaymember item. But I had also read some bugs around arrays and combo boxes, so I switched to a disconnected dataset. I had a heck of a time getting the combo box to load properly. I kept getting either no data in the combo box, or it kept showing the phrase "System.Data.DataRowView". I found out that you have to set the datasource property first, before you set the datamember and the valuemember properties. But the real kicker was that you can't use the datasource and get it to work if the sorted property on the combo box is set to true. It appears that if you set that property to true, then the combo box assumes you're going to do things the old VB6 way and use the Add items method to the combo box. My tipoff something was wrong that I'd watch the debugger, and right after the statement like this: cbTest.DataSource = dsInfo.Tables(0) the value of cbTest.Datasource was "nothing", like the assignment didnt take. In order to get things to work the way I wanted them to, I simply built a dataview that sorted the table for me, and fed that to the combobox with the sorted value off, and it finally worked. Three weeks later, of course. Would someone from Microsoft confirm that you shouldn't use datasource in combo and list boxes if you set the Sorted property to true in the form designer? If that is the case, note that somewhere in the MSDN information about the ListBox and the ComboBox classes!!

    - Strangeness in OnPaint Hi, In windows forms (vb.net), i use my own controls subclassed from base controls and i override the Onxxx methods. for example: Public Class MyBouton Inherits System.Windows.Forms.Button . Protected Overrides Sub OnPaint(ByVal pe As System.Windows.Forms.PaintEventArgs) MyBase.OnPaint(pe) . Protected Overrides Sub OnClick(ByVal e As System.EventArgs) Mybase.OnClick(e) . I saw that : - for some controls (ex: combobox), i can't access to OnPaint but i can access to OnClick .. - for these controls, if i had in the constructor : Me.SetStyle(ControlStyles.UserPaint, true) i can now access to OnPaint (then i must draw the control even if i put MyBase.OnPaint(pe)) but if i put : Me.SetStyle(ControlStyles.UserPaint, false) i can't access to none Onxxx - in some controls (ex: Button) without Me.SetStyle, it is ok, i can access to OnPaint I saw also if i intercept a windows message, it is ok : Protected Overrides Sub WndProc(ByRef m As Message) MyBase.WndProc(m) Select Case m.Msg Case &HF ' =15 =Paint Can anybody explain this strangeness ? Is it a known bug ? Is it better to use always windows message instead of OnPaint ? Thanks for advice.

App does the following: -Main entry point calls App.Run(new MainForm()) -MainFrom gets created -MainForm_Load() event handler creates a new LoginForm(), and does a form.ShowDialog() ...note, LoginForm:BaseForm, BaseForm:Windows.System.Forms.Form) At this point, I see a "flicker" for the login form, but does not hold up waiting for me to enter data/press OK button, etc... The LoginForm_Load() handler sets the DialogResult to CANCEL, so the switch/case processing the DialogResult after the call to ShowDialog() promptly ends.

    - Easy way to datatype validate TextBoxes In a form I have a number of textboxes that is to receive different types of data from the user. I can of course validate what has been typed in when the user press the Ok button by parsing through the contents of the individual textboxes. However, the .NET framework being so extensive, I was wondering if there were not already some smart way of handling this validation rather than having to program it by yourself. A datatype property that could be set on the textbox or perhaps an object that could parse and validate it according to datatype would come in handy. E.g. if you had a date TextBox, it could check that a valid date had been entered, or perhaps even preventing the user from enterering invalid data in the first place. For numbers it could be an enforced format with only so many digits allowed and thousand dividers and decimal points automatically displayed as well as any currency characters. I guess I am looking for something like the format that can be assigned to cells in Excel. There is a mention of format strings, but the purpose of these seems more to be a handling or display of a string which is already given, rather than validating an entry of data or even preventing something wrong from being entered in the first place. I hope anyone has some usuful suggestions. If not I can make some methods myself that I can put in a class for reuse. But with this huge framework, one would think that something so general was already included. Best regards, Frank M. Tag: Problem with Z-ordering !!! Tag: 78776

    - Question about WinForms Timers and calling Control.invoke I have read a few messages concerning the use of windows timers and have some questions concerning them. One of the messages hat I read stated that timers are called on a separate thread. If this is true, is it necessary to call Invoke when accessing forms controls within the timer function? I was always assuming that timers functioned the same way they do in C++. That is with a WM_TIMER message being dispatched. If the call is on a WM_TIMER message, then it should not be necessary to call invoke because you would already be on the context of the main window dispatch loop. If the Timer control is not using WM_TIMER, then I would wonder why this is so? It is sort of hard to identify with some of these .NET layers and how they interact at the WIN32 level if you had previously come from that environment. I just need some clarification. -- ----------------------------------- Ken Varn Senior Software Engineer Diebold Inc.

    - Can't wait for other process to finish I want to start another process in code, wait for it to finish, then continue. No problem, I do the following: prcs := System.Diagnostics.Process.Start('E:\blah.txt'); if assigned(prcs) then begin prcs.WaitForExit; prcs.Close; end; This works fine if my default application for the given file type is not already running. If it is running and it handles multiple open documents, it will just open a new document in the same process in which case prcs is not assigned (null) because it didn't actually start the process. Then of course, I can't wait for the process to exit. Is there any way to get a pointer/handle to the process in these cases? Tag: Problem with Z-ordering !!! Tag: 78770

    - System.OutOfMemory exception: error creating window handle Hi, Software: .NET 1.1 (both non-SP and SP1) Visual Studio .NET 2003 MS SQL Server 2000 SP3 Windows XP SP 2 Hardware: Intel Celeron 1700, Pentium 4 2.4GHz, AMD Athlon 1100 RAM 256-512 DDR I've run into a strange problem. There is an application which allows to: 1) connect to a certain device using a modem 2) manage different aspects (mostly, working with MS SQL Server) Serial communication is done on a separate thread, one per each connection. The maximum number of simultaneous connections is 20. Note: what is written below applies only when running the application not under the debugger. The app starts and works correctly: accepts incoming calls, performs different scenarios, dials out when necessary. When the comms thread needs to modify the UI, it is correctly done using Control.BeginInvoke. However, sometimes (on different computers) the following exception is thrown: System.OutOfMemory exception: error creating window handle ---> System.NullReferenceException: Object reference not set to an instance of object. at System.Windows.Forms.ThreadContext.OnThreadException at System.Windows.Forms.Control.WndProcException at System.Windows.Forms.ControlNativeWindow.OnThreadException at System.Windows.Forms.NativeWindow.Callback(IntPtr, Int32, IntPtr, IntPtr) at System.Windows.Forms.UnsafeNativeMethods.IntCreateWindowEx(int32, string, string, int32, int32, int32, int32, int32, HandleRef, HandleRef, HandleRef, object) at System.Windows.Forms.UnsafeNativeMethods.CreateWindowEx(int32, string, string, int32, int32, int32, int32, int32, HandleRef, HandleRef, HandleRef, object) at System.Windows.Forms.NativeWindow.CreateHandle(CreateParams) -- End of inner exception stack trace -- at System.Windows.Forms.ThreadContext.OnThreadException at System.Windows.Forms.Control.WndProcException at System.Windows.Forms.ControlNativeWindow.OnThreadException at System.Windows.Forms.SafeNativeMethods.ShowWindow(HandleRef, int32) at System.Windows.Forms.Control.SetVisibleCore at System.Windows.Forms.Form.SetVisibleCore at System.Windows.Forms.Control.set_Visible at System.Windows.Forms.Form.ShowDialog(IWin32Window owner) at System.Windows.Forms.Form.ShowDialog at <my form-my code to ShowDialog> What could be the problem? Let me stress that this does not happen under debuggers. When debugging, the exception is not thrown. It was noted that this happens more often when having an active connection. -- Regards, Serge (Logic Software) Tag: Problem with Z-ordering !!! Tag: 78743

    - Parse method never called when data binding from class property to textedit I'm using C# and having problems getting the 'Parse' EventHandler of my binding object to be called. Interestingly, the 'Format' method is always called however. A code snippet: (rdDocument is a private member field of the class and has a string-type property called 'Name') Binding bName = new Binding("Text", rdDocument, "Name"); bName.Format += new ConvertEventHandler(teName_Format); bName.Parse += new ConvertEventHandler(teName_Validate); textBox1.DataBindings.Add(bName); private void teName_Format(object sender, ConvertEventArgs e) { <perform formatting, OK: method always called> } private void teName_Validate(object sender, ConvertEventArgs e) { string sValue = (string) e.Value; <perform validation, PROBLEM: method never called> } Can anybody tell me why it's not being called or how I can force it to be called?

    - Showing a UITypeEditor at Run-time How can I get a custom UITypeEditor to show up in the PropertyGrid at runtime? The examples out there all seem to work at design time inside Visual Studio, but if you put a PropertyGrid control on your form and set SelectedObject at runtime, the same custom editor doesn't show up. The closest thing I've found in searching the newsgroups was the following comment by Shawn Burke . I would be very grateful if anyone could expand on this or point me in the direction of some sample code. > Take a look at IWindowsFormsEditorService. You'll need to implement this, > get the editor from an object by calling TypeDescriptor.GetEditor(object, > typeof(UITypeEditor)), and then calling it with an IServiceProvider that can > create your IWindowsFormsEditorService implementation.

    - control data binding not happening when data entered from app I have a textbox, which is bound to a class member: textBoxDataServerhostname.DataBindings.Add("Text", localOptions, "DataServerHostname"); The text can be entered by the user, or sometimes generated from code, for example: textBoxDataServerhostname.Text = anotherTextBox.Text; When text is entered by the user, the class member is updated correctly; when it's generated from code, the member is unchanged. How do i get this to work (I want the member to change when the textbox is changed from code)? I have tried setting Modified = true, and setting ReadOnly = false (in the case where the text is generated by code, the control is read only). Thanks in advance for any help...

    - Problem with column headers when right justifying Datagrid columns Has anyone else noticed this? When I right justify a column in a datagrid, part of the header text is hidden, at least the rightmost character. Is this a bug or is there something I'm forgetting to set? This happens whether I declare columns programmatically or through the visual designer. (Sorry if I'm posting so many grid questions. I normally have little use for the grid but my new job has changed all that. Thanks.) Tag: Problem with Z-ordering !!! Tag: 78715
