    - ScrollControlIntoView c# Hi I have a problem with displaying textBoxes in a tabPage on a form. I have 3 tabs, the 2nd tab 'tab2' the user enter the number of textBoxes required to be displayed in 'tab3', when they leave 'tab2' and click on 'tab3' the code place the textboxes at the bottom of 'tab3' adding additional ones above them. This requires the 'AutoScroll' to start at the bottom of 'tab3'. I'm using 'ScrollControlIntoView' to display the textBox. When you first click on 'tab3' from 'tab2', the scroll bars do not go to the bottom of the 'tab3' where the text boxes are added. However this works the 2nd time you click 'tab3' and the scroll bars start at the bottom of 'tab3' where the textboxes are placed. Can anyone help? I have supplied the basic code I'm using.

    - Deploying native code. The scenario is we're about to release an exe to our clients. It's a winforms application that uses reflection, remoting, generics, and serialization. We want to protect the intellectual proprety rights of our code. One solution is to obfuscate the exe. I've come across some 3rd party solutions that claim they can compile the exe to native code (xenocode, remotesoft, etc). I'm wondering if there is some tool in the .NET framework that can compile winforms applications directly to native code, thereby bypassing MSIL + JIT compilation? The native executable can then be deployed. I've read about the ngen utility, but it doesn't seem applicable in this case. From my understanding, ngen will precompile the exe and add it to the native image cache on the respective machine. What I'm looking for here is a way to bypass MSIL + JIT compilation. Thank you!

    - setting ShowInTaskBar to 'false at run-time : strange errors, crashes .NET 2.0, Visual Studio 2005 Hi, I have several open windows, all instances of the same form template created dynamically in response to a user action at run-time. A user option for the application is to show all open windows in the task bar, or only the current active window. I thought I could write handlers for the Form_Activated and Form_Deactivate events of all these instances of a form_template, but I'm running into strange errors when I set 'ShowInTaskBar to false in the 'Deactivate event like : "can't create window handle," or "callback on a delegate that has been garbage collected." At first I thought these error might be related to deisgn mode, but they persist when I run the .exe file, giving an error dialogue that does not provide the usual debugging information. Googling on "microsoft: showintaskbar" led to several reports that suggest errors with setting showintaskbar to false at runtime. Francisco Balena at : http://www.devx.com/vb2themax/Tip/18334 Says the property is read-only at run-time, but in another part of my application I have a menu that toggles showing all, or only the active form, in the taskbar : this code loops through a collection of open forms I maintain and sets showintaskbar properly and with no errors ! I am aware that winforms does some strange stuff when you set ShowInTaskBar to 'false : "After doing some research, I found that setting Form.ShowInTaskbar=false will close window's WS_EX_APPWINDOW flag, and set window's owner form to WindowsFormsParkingWindow, which is an invisible toplevel window(internal )" comments Jeffrey Tan from Microsoft at : http://www.dotnet247.com/247reference/msgs/57/285697.aspx Okay my questions : 1. is switching a window's ShowInTaskBar status something that will require use of Interop and API's in .NET 2.0 ? 2. has there been a change in versions of .NET > 2.0 that make this possible without use of API's. In this particular design scenario there is no one window which is always necessarily visible, no "master form." Each winform created has its Parent property set to Null. And, yes, Form_Closing events are modified to detect need to terminate the app because, in this case I am using Application.Run() after an initial template form is shown. thanks, Bill Tag: Media Control >> Tag readers Tag: 116909

    - NotifyIcon on a Dialog Box [Using VB.NET 2005] We've got an old application that has been modified quite a bit. Originally, it was just a single form application that hid in the Task Bar Tray using a Notify Icon. Later, we had to add a Custom Dialog Box to the project. Now, it has been determined that the project would be best served by the Dialog Box only, and eliminate the main form. So, the project is now a Console-like Application that starts with a Main Module. The Notify Icon had to be included with the Dialog Box, otherwise we weren't able to make it work. The Notify Icon has a Context Menu Strip and events for Click and Double Click. When the Main Module starts, it creates a new instance of the Dialog Box, but does not show it. When the Dialog Box is created, it creates and shows the Notify Icon. If you are still reading this, here is the problem: Unless the Dialog Box is being displayed (dialog1.ShowModal), all the Notify Icon will do is show its Balloon Message. The Click, Double Click, and Context Menu Strip does not react at all. Any idea why? How would I get this to work? Tag: Media Control >> Tag readers Tag: 116908

    - Need 2nd opinion about program style This might be a silly question but.... I have not made much use of modules in recent years. I've been called on to translate an old VB6 program to Dot Net 2.0. Aside from the sheer complexity and lack of docs, there is one thing that caught my attention: The original programmer made a great deal of use of modules in his DLLs. One element of his style was to create class declarations in the module (Public x as Class1) and then set x to reference the class in the class itself (x = Me). Now I've whipped up a little test program and I know this still works but I was just wondering how this measures up as acceptable (or should I say 'modern') programming style? (It seems an innocent enough technique but given that the legacy program as a whole is major spaghetti, I thought I'd ask for a second opinion.) Tag: Media Control >> Tag readers Tag: 116907

    - ".resx" files not kept up-to-date by Visual Studio Hi there, Can anyone explain why the assembly qualified names seen in the ".resx" file for each form in an application aren't kept up-to-date by Visual Studio. For instance, if a dialog uses a user control from some other library in the same solution, the user control's assembly qualified name will appear in the dialog's ".resx" file. Each time the control's library is compiled however, the library's version is incremented but the ".resx" file continues to show the original version number. How then does Visual Studio load it when the dialog is displayed in the Visual Studio designer? If all projects are signed then the control's library identity won't match what's in the '.resx" file but Visual Studio seems to ignore this. Can anyone shed any light on the situation? Thanks in advance. Tag: Media Control >> Tag readers Tag: 116898

    - Bug in ComboBox with AutoCompletion? Hi, I have a strange problem. The Combobox component always raises an OnTextChanged event when it is validated and auto completion is activate. Take a look at .NET framework source code, ComboBox.cs, method "OnValidating". This method calls "NotifyAutoComplete()", which itself calls "OnTextChanged" when the selected index was not changed - it does not check if the text was really changed! This for example causes that the OnTextChanged event is always raised when the ComboBox looses focus. There are several other ways where the event is raised where it should not. Any ideas?

    - General question about VB6-Dot Net conversion I've been tasked with converting a VB6 exe (plus associated dlls.) The conversion is not supposed to be exact so the conversion wizard is probably not an option.

Can anyone point me to a favorite reference or discussion on this subject? (I can probably wing it but I'd like to avoid common pitfalls.) Tag: Media Control >> Tag readers Tag: 116896

    - Button stuck disabled when running under VS Debugger Hello all, I'm experiencing a samewhat strange behaviour when running my Windows Forms app from withing Visual Studio 2008. The application is multithreaded and the workerthread fires an event that should enable a button in the GUI. I'm using BeginInvoke to call the method that enables the button on the GUI thread. The code is very straight forward: On the worker thread: [...] ffmpegProcess.WaitForExit(); if (GeneratorFinished != null) { GeneratorFinished(this, null); //event that triggers the button enabler } In the GUI Class: void generator_GeneratorFinished(object sender, EventArgs e) { if (this.InvokeRequired) { MethodInvoker invoker = new MethodInvoker(EnableStartButton); invoker.BeginInvoke(null, null); } else { EnableStartButton(); } } private void EnableStartButton() { btnStart.Enabled = true; } This works as expected when running the program outside of VS. However if I start the Program within VS (by hitting F5) the Button does change its appearance from disabled to enabled but does still not accept mouse input. The button works when I press the accelerator key (Alt+S). I can also tab to the button (it recieves focus) and press enter. However tabbing to it and pressing space doesn't work. Once the button got activated via tab+enter or the accelerator key it 'unsticks' and accepts mouse input again. It's not a big deal but a little annyoing and I'm curious if there's anything I can do to prevent it from happening? Thanks Ben Tag: Media Control >> Tag readers Tag: 116869

    - ClickOnce: Certificate cannot be validated Hi, We are signing our ClickOnce manifests with a code signing certificate purchased from Thawte. When we install the software a security warning is shown, and when we click on the publisher it says the certificate can not be validated. This is because the "Thawte Code Signing CA" is not present on the client machines. Having done a web search, I found a previous post in this group describing exactly the same issue - viewable at: http://groups.google.com/group/microsoft.public.dotnet.framework.windowsforms/browse_thread/thread/8c46df2acf25d54/4c1c4221f69fa09e From one reply from Linda Liu [MSFT]: >I searched in our inner database and found a similar issue in it. The >following is the comments: > >Firstly, this is a known issue that is being addressed in the next version >of Visual Studio - The Orcas. >Click Once apps do not distribute certificate/cert chains on the fly. So >for path validation to be recognized at install time - the installing >machine must have the intermediate certificate in this specific case. My investigations have not yet turned up any CAs that offer code signing certificates that directly chain from certificates we will find on our very vanilla customer machines - they all seem to use intermediate certs. (I'd love to be proved wrong on this...) My real question relates to the comment that this is being addressed in the Orcas release of Visual Studio. Is this true? If so, is there support in framework 3.5 that can be accessed via cClickOnce APIs? Thanks, Tony Tag: Media Control >> Tag readers Tag: 116861

    - Can I create a Windows Explorer Icon type object in .NET I am trying to create a Windows Explorer icon type object in .NET that will display an icon image and have a label that works like the label on an icon in Windows Explorer; maximum two-line display that expands to full-size when selected and is editable. I would also like to be able to have it contained on a Form and be able to reposition it by changing a "Location" property. I have experimented with PictureBox and Panel box objects without any success. Is there such an object available in .NET (or natively)? The editable label is especially interesting. For now I have implemented a static display use the various Graphic class methods; DrawImage and DrawString but they really do not replace the advantage of having a true icon type object that I could click and manipulate.

    - TableNewRow event handling issue Greetings, Using VS 2005 SP1; I created a simple form by dragging and dropping a data table. I changed it to a details view, so I have a mixture of text boxes, combo boxes and a check box (no dgv). I want to programatically populate the controls when the user clicks on the Add New button, so I added the following event handler: void MyDataTable_TableNewRow(object sender, DataTableNewRowEventArgs e) { int nIndex = int.Parse(this.bindingNavigatorPositionItem.Text); e.Row.BeginEdit(); e.Row["Col0"] = this.myDataSet.MyDataTable.Rows[nIndex].ItemArray[0].ToString(); e.Row["Col1"] = this.myDataSet.MyDataTable.Rows[nIndex].ItemArray[1].ToString(); e.Row["Col2"] = this.myDataSet.MyDataTable.Rows[nIndex].ItemArray[2].ToString(); ...etc... e.Row.EndEdit(); } This works surprisingly well; the user can select any row and use it as a template for the new row. I tried to take this a step further; instead of setting the columns individually, I tried to use the CopyTo function as follows: void MyDataTable_TableNewRow(object sender, DataTableNewRowEventArgs e) { int nIndex = int.Parse(this.bindingNavigatorPositionItem.Text); e.Row.BeginEdit(); this.myDataSet.MyDataTable.Rows[nIndex].ItemArray.CopyTo(e.Row.ItemArray, 0); e.Row.EndEdit(); } The code seems to execute, but all my controls are blank, like the CopyTo did nothing; what am I missing here? Shouldn't this work? -- Regards, Bob Tag: Media Control >> Tag readers Tag: 116843

    - Slow app response Hi I have replaced an ms access app with its vb.net version at a client site. Now the clients keeps complaining about how slow the app response is. The complains they have are for example when app is minimised and then trying to maximise it after a while takes a while for app to get maximised. Also form painting of controls is slow and app is generally slow in terms of response to user clicks. I am using Infragistics controls and my feeling is that makes the app bit sluggish compared to the original controls shipped with vs 2008 but I need the Infragistics controls for their features. I have also ngen'd the app but surprisingly only the main app executable gets ngen'd and not any of the dependency dlls such as Infragistics dlls.

    - Getting TextBox default height Is there a way to get the height of a textbox without creating one? Basically I can use this: TextBox tbox = new TextBox(); height = tbox.Height; but I would rather not create a temporary object if there is some static method to get the height. I want to draw some rectangles that have the same height as the default TextBox. Tag: Media Control >> Tag readers Tag: 116797

    - Converting a DataColumn's Datatype on the fly Hi everyone, I have one dataset that gets built dynamically from XML, I parse a large soap message and extract the schema from XML( I am working in .NET 1.0, sorry for the pain). anyway, by default the dataset resutling from this process has a data type of string for all columns. My question is : Is there a way to convert the datatype of columns from String to Double, or to any other format, on the fly? I know for a fact that all values in that datacolumn are all doubles. One thing I am doing is creating a new column with a datatype of double, and then looping through all existing row in the string column and then converting them, but this is a nightmare as the size of the table grows. Thank you. Tag: Media Control >> Tag readers Tag: 116796

    - Driving me nuts! How to do two-levels inheritance under UserControl? I have a few types of panels (each with different controls), which I will create dynamically and place on a form. I can make them UserControls if I need to. However I would like to have a base class for these, so that I have a class hierarchy like: System.Windows.Forms.Panel | | MyBasePanelClassWithOverridableMethods | | | | MyPanelType1 MyPanelType2 I tried to create a UserControl and inserted a base class within Notepad, changing: ---------------------- Partial Class UserControl1 Inherits System.Windows.Forms.UserControl --------------------- To: ---------------------- Partial Class MyBaseUserControl Inherits System.Windows.Forms.UserControl End Class Partial Class UserControl1 Inherits Class MyBaseUserControl ------------------------ ...and DevStudio2008 gives me an error "Value does not fall within expected range", which is useless. Is there something more I need to do to insert my base class? Is there another way to achieve what I need to achieve? I need MyPanelType1 and MyPanelType2 to be editable as far as contained controls, etc... Thanks! Tag: Media Control >> Tag readers Tag: 116791

    - tracking logged in User I have a winform app that validates a user against a table in my database. I want to track the user throughout the program for maintaining permissions to access parts of the program etc. In a web app, I would just throw the current user into a session varaible and access it from any webform. What's the proper way to do this in a winform app? Bill Tag: Media Control >> Tag readers Tag: 116775

    - ToolStripComboBox.ComboBox What is the deal with this property? As long as the ToolStripComboBox is visible on the ToolStrip, it seems to work fine. However, if the ToolStrip gets shrunk to a size that the ToolStripComboBox is only accessable through the extension button, the ComboBox property starts behaving in a manner that I do not expect. In particular the SelectedValue property does not work. Is this by design? I can not find any articles explaining why the ComboBox would not always just work.

    - Using OCX in a Windows Service Hello there, I am creating a windows service to monitor wireless terminals and then transmit the barcodes to the clients. The service needs to use a OCX (I hate to use OCX in a service but, without OCX, you wont be connected to the base station). I have added a form and used the ocx on the form only to connect to the base station. However, I do get a message in the event log. The service won't start. Service cannot be started. System.Threading.ThreadStateException: ActiveX control '244758c6-a002-11d2-b82b-938daecfce37' cannot be instantiated because the current thread is not in a single-threaded apartment. at System.Windows.Forms.AxHost..ctor(String clsid, Int32 flags) at System.Windows.Forms.AxHost..ctor(String clsid) at AxPLSERVERLib.AxPLServer..ctor() at WHE.PandD.WHEPLSContainer.InitializeComponent() at WHE.PandD.WHEPLSContainer..ctor() at WHE.PandD.WHEDespatchServiceFacade.StartWorking() at WHE.PandD.WHEDespatchService.OnStart(String[] args) at System.ServiceProcess.ServiceBase.ServiceQueuedMainCallback(Object state) For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.
