    - MDI Positioning Hello, I am creating a MDI child window from a MDI parent window. I have tried setting the Left and Top members before calling Show() and it seems to have no effect. If I set Left and Top after calling Show() the form flashes in the default location and moves into the position I set with Left and Top. My question is how do I get the MDI child to appear in the location that I want, without the flash? Thanks, Shawn Tag: NumericUpDOwn Tag: 99909

    - .Net 2.0 Split Container and Tab Control Format Issue I am having a layout issue I can't seem to work out in Visual Studio 2005. I have a Windows form with a Split Container. In the second panel (right side) I have a tab control. The tab control has anchor properties of left, right, top, and bottom. It also has its dock property set to "Fill". When the application loads the tab control is properly sized to 100% of the second panel in the split container. When I pull the splitter to the left the tab control does not autosize with the splitter panel as it gets larger. If I use the forms minimize or maximize buttons it corrects the size issue of the tab control for the spilt I put into the panel. Am I missing something to that I need to set on one of those controls so that the tab control grows with the panel as it gets larger? Any advise? Amy. Tag: NumericUpDOwn Tag: 99908

    - Dependency between two DataGridViewComboBoxColumn Hi, I'm doing a DataGridView with two ComboBox columns. In the first ComboBox I've all the sates of a country and in the second I've the counties of each state. I need to create a dependency between the two ComboBox, in such a way that in the second ComboBox just appear the counties that belong to the state selected in the first ComboBox. To accomplish the task I've been created a TableAdapter which contains all the counties and a DataView to filter this TableAdapter. In this way everything work, but when I change the "state" (in the first ComboBox) to a different value when I move the mouse over the second ComboBox in a row that has a county that belong to another state I get the following exception "System.ArgumentException: DataGridViewComboBoxCell value is not valid." I know that the problem arises because the DataView is filtered to some "state" different than the state that the county belongs to. Does anybody know how can I fix it? Maybe there's another way to accomplish the task. I just need to resolve this. Thanks, Robe. Tag: NumericUpDOwn Tag: 99905

    - [C#] RichTextBox autoscroll after style change Hi, I'm working on a RichTextBox with some "in-program" style-features (e.g. *no way* becomes bold : like MS Word does). Got everything working fine, flickerfree and reasonable fast, but in order to set the style of some part of the text I use the "Selection" method (in the case of *text* the richTextBox1.SelectionFont.Bold = true No problem so far, unless there are scrollbars involved. Somehow, when I type into the RichTextBox (and after the styles are applied) the current selection position becomes the top row; unless there is no "scrollbar left" to scroll down to. I've added a small sample of the code below [Code] Cursor = Cursors.WaitCursor; int origSelStart = richTextBox1.SelectionStart; int origSelLength = richTextBox1.SelectionLength; // Freeze control SendMessage(richTextBox1.Handle, 11, 0, 0); if (SingleLine) { // Only do the appropriate line ApplyLineStyle(Line); } else { // Apply style on all lines for (int i = 0; i < richTextBox1.Lines.GetLength(0); i++) { ApplyLineStyle(i, false); } } // Unfreeze control SendMessage(richTextBox1.Handle, 11, 1, 0); richTextBox1.Refresh(); // Turn original selection-state back richTextBox1.SelectionStart = origSelStart; richTextBox1.SelectionLength = origSelLength; SingleLine = false; Cursor = Cursors.Default; [/Code] What am I missing, is there a property or method I could use?

    - Modal app [2.0] I have written a signature capture mini-app for tablet PCs. The way this works is that our main application calls this little app with a command line arg of the jpg name to save the signature to. The app consists entirely of a single form with an ink gathering control and 2 buttons so the user can cancel or save the signature. We need this little signature app to be on top of everything at all times. The client has specified that the user should not be able to do anything at all until they have either hit the 'Done' button or the 'Cancel' button. What's the best way to accomplish this? I can think of a few different ways to do it, but I'm unsure what the recommended way is. Tag: NumericUpDOwn Tag: 99895

    - Does a Window have to be visible to receive Messages I am trying to monitor incoming messages by overriding the System.windows.form WndProc method. I have a radar device that sends messages via the Message parameter for the WndProc method.

    - Simple "Browse for a file" control I apologize that I am new to windows forms programming. I'm looking for the correct control or components to use to create standard browse-for-a-file capability. I'd like to have a textbox and a button next to it that says "Browse". When you click the browse button you would get the standard windows api dialog that allows you to browse for a particular file. When the user finds his/her file, they would select it and the textbox would be populated with their selection. This is very easy to do with web / html controls, but I've never had to do it in a windows form unfortunately. I've done a bit of googling and I'm getting results for a lot of custom / enhanced solutions. I'm looking for a simple example. If anyone could please provide some direction I'd greatly appreciate it. -- PK9 Tag: NumericUpDOwn Tag: 99870

    - RichTextBox woes My app needs to load a plaintext file (1 to 15MBs), edit & convert it to rtf, and finally output it to a RichTextBox (RTB). Simple enough... Loading a 5MB file (average case for this app) and editing/converting it to an rtf string takes about 1 second to accomplish...no big deal. However, doing a "myRTB.Rtf = myRtfString;" takes another 25-30 more seconds!. That's even after I've hidden the RTB and prevented the underlying RichEdit control from generating WM_PAINT & other events while I'm updating it (via SendMessage SET_REDRAW & EM_SETEVENTMASK respectively). Anyway, I'm out of ideas when it comes to speeding up the RTB since it seems from my research that slowness is a longstanding problem with the underlying RichEdit. I should also mention that I don't want to get into partial loading/editing...I've tried it...it had its own set of issues. So in light of the above problem...is there a safe way to update the RTB's.Rtf property from within a thread? My goal now is to: a) update the RTB in the background thread (if possible) so I don't lost app responsiveness b) allow a user to cancel the operation if they choose to do so TIA! -sb Tag: NumericUpDOwn Tag: 99866

    - Window size control I wish to have a window whose width can be resized but not its height. I tried this: this.MaximumSize = new System.Drawing.Size(0, 300); this.MinimumSize = new System.Drawing.Size(0, 300); which according to the documentation on MaximumSize and MinimumSize should accomplish what I want. The 0's are supposed to mean that only the system limits apply. What is occurring is that the form appears with minimal width, the correct height and the form is not resizable in any direction. Can anyone clear this up for me? Regards Chris Saunders Tag: NumericUpDOwn Tag: 99856

    - ContextMenuStrip showing only after second right mose click Hello! I upgraded my legacy .NET 1.1 application to .NET new ToolStrip controls and everything seems to work OK except some wierd ContextMenuStrip behaviour. ContextMenuStrip is bound to several controls on the Form (Form itselfs, TabControl, DataGrids inside tabs) and in ContextMenuStrip.Opening event all ToolStripMenuItems are created and added to the ContextMenuStrip (they are removed and disposed after use). But the strange thing is that when user clicks the right mose button for the first time during process lifespan context menu does not show up. ContextMenuStrip.Opening event is raised, items are created and added (I checked it with tracing) and menu is not shown. The very same event raised second time shows context menu. Now I have changed initial context menu content (it was empty at the start by design) by adding single dummy ToolStripMenuItem during initialization which obviosuly is removed and destroyed and everything works fine. I do consider this kind of behaviour being a bug - can somone from MSFT comment on this. Cheers http://sourceforge.net/projects/ngmp Tag: NumericUpDOwn Tag: 99855

    - more clues on my multithread problem Hi there i have discovered that my application entirely hangs when the modeless dialog needs to be repainted. Then all the UI becomes unresponsive and the debugger dont let me pause the execution to see where it is each of the threads . The modeless dialog stays as it is been working on something because when i put the mouse cursor over it it changes to the sand watch icon. The main form of the application is no more repainted and i cando nothing except stopping the debugging process (an operation which takes more time than in a normal situation). Does this has a meaning for anyone? A question i have is:What happens when you call the Invoke method on a form to execute a delegate?Does the form stop its message pump to execute the delegate or a message is sent indicating the form that it has to execute that operation? could be the problem in there? Thanks, im getting mad with this project Tag: NumericUpDOwn Tag: 99831

    - Message queue in modeless dialogs Hi, i have a multithreaded application which uses forms and i have a worker thread that has to create a modeless dialog to monitor some of the operation which it has to do. The problem is that if you create the dialog and call show() from the thread this dialog wont't have a message queue and will become unresponsive. I found in a page that you have to create the dialog in the main UI thread.In that case the message queue of the main form will be shared among the main form of my application and the modeless dialog i have created, but there is a problem. If one of them hangs up the other too will hang. The problem is that my application hangs at one point and i dont know exactly the reason , the only thing i know is that it has to be something like a deadlock that causes one of the forms become unresponsive. I want the modeless dialog to have its own message queue independent from the main UI message queue, Â¿how i can do that? i have tried to create a new thread which executes application.run again as i have read that this method creates a message queue for the thread who calls it but the result was not the expected one: my modeless dialog runs ,be sure of it but when i call application exit in the thread of the modeless dialog all the application exit, not only the thread which i was pretending to be th ethread of teh dialog, follow me?

    - PropertyGrid with duplicate DisplayNames Hi group, I have a problem using the PropertyGrid. I'm using a PropertyGrid to show a dynamically generated option dialog. I use an ICustomTypeDescriptor implementation together with a custom PropertyDescriptor that fakes out the needed "properties" for the grid, the actual values coming from a different data source, that can also changed programmatically. The PropertyDescriptor fakes a human friendly DisplayName and an unique PropertyName that is only used internally. Problem: When doing a propertyGrid.Refresh(), GridItems with duplicate DisplayNames are not handled correctly, specifically: If I change the value for any but the first one (in current sort order), after the refresh the FIRST one is always selected, and it shows the string representation of the currently changed entry (however, it DOES paint the value representation correctly). The string representation is only displayed incorrectly, i.e. it is not written back, and after any focus changes, it is displayed correctly. Also, if I make the DisplayNames unique, or the PropertyType differs, the problem goes away. It also does not depend on the PropertyDescriptor/ICustomTypeDescriptor combo, but happens even with static properties (just checked ;-)) Has anyone else encountered this or a similar problem and/or has any tips?

    - Problem with multithreaded application (Cont.) Let me be more explicit on the problem: i've been making some testings on my application and i realized that the application hangs in this situation: I have a main window created in the thread which called Application.Run so it has the message loop right? Well, then i have another thread wich represents an entity which has to do its own operations (worker thread created with the thread object) .Then i ask my thread object to show a monitor where it has to write its progress in the operation, this monitor is a non-modal dialog. The worker thread calls a method to obtain the form which represents that monitor: this method will do a call of the Invoke method in the form object which represents the main form of the application and which was created in the thread which called the Application.Run method,follow me? : ) .this invoking is to ask the UI thread to create a monitor form object (i have to create the monitor object in the UI Thread as it will be a non modal dialog which i will show using its Show method so it won't have a message queue by itself ,this is the opposite to what happens if i want it to be a modal dialog:then i call the showdialog method and it will have its own messagequeue and it is not necessary for it to be created in the UI Thread) well thn the worker thread gets its monitor form object and do an Invoke to call its Show method to display it. Periodically the worker thread will do an Invoking to call a methos wich updates the fields of the monitor object. Well everything goes fine but when the monitor is running and i start moving the main form from one side to other of the screen then the hang of the application comes up. I think that it could be because i created the monitor object in such a way that it share the messagequeu of the main form of the application(creating this object in the UI Thread). The problem is that i havent found the way to give a non modal dialog its own message queue independent of the message queu of teh main form. anybodu thinks that this could be the problem????

    - Problem with multithread application Hi there.Im building a multithreaded application which uses forms and im having some problems possibly due to my inexperience. The project is being developed in C# with visual studio 2005. I have a main thread which executes Application.Run() (so it has the message loop for the interface) and later i create more threads that are executing and in some situations have to do some operations in the UI. Some threads also query the UI the creation of non-modal dialogs to show information "on the fly". There arent cross-threaded operations in the UI, im sure of that. All the operations have been queried using the InvokeRequired attribute and the Invoke Method (i have used only the Invoke method instead of using BeginInvoke too) so all the operations on the UI are done in the Thread tha run Application.Run (the UI thread). When i execute my application everything goes fine buty sometimes when i execute it and push some button of one of the windows or when i close one of that windows etc etc my application hangs (well i dont know if my application but at least the UI). I think that the problem is in that im not considering some issue of the using of the UI in multithreading applications, maybe it is taking place a deadlock when im quering the UI tread some operations from different threads Â¿someone can advise me or has any idea about what can be happening? thanks Tag: NumericUpDOwn Tag: 99795

    - Win application freezes on datagrid scroll event Hallo, I'm experiencing an eerie trouble using datagrids on Windows application with .NET framework 2.0 Being concise, I say that my applications polls the serial port by means of a separate thread. When some information is found on the tool connected to the port (a GSM phone), such an information (SMS) is put in the db and then an event is raised. When such an event is raised, the delegate invokes an appropriate method that refreshes the datagrid: every row in the grid is one received SMS. The refreshing is made by the separate thread, so it is called the appropriate method that enables separate threads to interact with the objects and controls of the UserInterface belonging to the main thread, as it is meant to be. Ok, everything works fine but, say that the datagrid control can show 16 items before the vertical scrollbar appears, when the 17th item has to be shown, instead to visualize the vertical scrollbar, the whole application freezes. No errors are thrown: just freezes - not responding application. Need to kill and restart, and so it's ok: vertical scrollbar appear. I've to say that this behaviour doesn't happen always. Almost always. I mean, sometimes 20 or more SMS are found in the GSM and correctly shown in the datagrid with scrollbar, but the most of times when the 17th is shown, application freezes. I'd be glad if someone could shed some light upon this strange, and unpredictable, event. Many thanks, Paolo P Tag: NumericUpDOwn Tag: 99788

What i found is that MeasureString sometimes returns the height which is smaller then it should be and it seems to depended on the width. So the question is am i doing something wrong or it's a bug. If it is a bug, can someone recomend a reliable workaround. Here is a code that used to test this. When width is set to 570, the last line is not visible. When it's set to 590 all is OK. Sub TestMeasureString(ByVal g As Graphics) Dim s As Size Dim f As Font = New Font("Arial", 11.25, FontStyle.Regular, GraphicsUnit.Point) Dim str As String = New String("W"c, 1000) & " END" s = g.MeasureString(str, f, 570).ToSize 's = g.MeasureString(str, f, 590).ToSize g.DrawRectangle(Pens.Black, New Rectangle(New Point(0, 0), s)) g.DrawString(str, f, Brushes.Black, New Rectangle(New Point(0, 0), s)) End Sub Tag: NumericUpDOwn Tag: 99783

    - read guid I have a vb.net 2.0 project where I need to read a files guid. Is this even possible? I need to do this via CODE, no 3rd party app please. Can I generate guids all day long but I want to read what a dll file has already been assigned. I know I can painfully search the registry. But there must be a better way. They are vb6 dll's, so they have a type library file. Can that be used? i.e. file "testds.dll" = {000-....} Thanx. Tag: NumericUpDOwn Tag: 99779

    - Question on Inheriting Controls I have a project which is a Windows Form "Wizard". Each "page" displayed in the main Wizard form will be a user control. Each of these user controls will share many similar attributes. So it seems natural for me to create a base user control class and have all my "pages" inherit from it. But it seems that VS2005 really isn't happy doing this unless the base class is compiled and put into an assembly other than the one containing my project. The visual designer get al hosed up and complains. I can force it all to work by hand-coding some changes but this seems way harder than it should be. Is there something I am missing here? Thanks.

    - DataSet and Usercontrol TestContainer has a Problem I have a WebService that has a method that returns a Typed DataSet. I create a UserControl that calls this method. When the UserControl runs by "UserControl TestContainer" and calls the WebService's method which returns a Typed DataSet the error "There is an error in XML document (1, 220)." is thrown. I don't know what's is wrong. This problem only occurs when Typed DataSet is returned and running by "UserControl TestContainer". I'm using .Net Framework 2.0 and VS 2005. Could someone help me?

    - RichEditBox speed Is there anyway to speed up the selecting and coloring of text in a richedit. The parsing of the text is nothing in comparison with how long it takes these two calls to take place (over many lines): rtb.Select(currentPos, myLine.Length); rtb.SelectionColor = myColor; From my research, there are a few ways to speed up the richedit but none of them help speed up the coloring process: 1) Inherit from the RichEdit and in an overloaded WndProc, ignore WM_PAINTs while updating 2) Use SendMessage to pause redraws/events (EM_SETEVENTMASK, SETREDRAW)while updating 3) Hide the RichTextBox while updating (seems to work the best...but it is still slow) Does anyone else out there have any better suggestions? I want to color the entire richeditbox in one sweep...so I don't have flickering or other noticeable side-effects caused by scrolling. I'm not looking to use a 3rd party control either for a number of reasons. TIA! sb Tag: NumericUpDOwn Tag: 99769

Hi,

If users change the value of NumericUpDown by clicking the arrows, this
change can be trapped with the .ValueCHanged event. But .ValueCHanged will
not work if users change from keyboard?
How do I trap all changes in NumericUpDown no matter if instigated from
arrow keys or from keyboard or even from Cut/Paste

I usually also set the keypress event and update the value with that as well
to get around this.
