    - Bug in VS.NET 2005 for click-once deployment It appears there's a bug in Visual Studio 2005 when trying to deploy a click-once application (this is a completely different issue than my last post, in case anyone's keeping track). When I set my publishing settings, the first time, it works just fine. When I want to publish to a different server, the part of the publish wizard that asks "How will users install the application?", the "From a Web site" setting is ignored and the original value I entered from the FIRST deployment is used. Now, once in a blue moon, it'll change, but it's unpredictable and rare. The only way I've found to "fix" it is to use a file searching utility (I use TextPad's "Search in files" feature) to search all files in the entire solution folder tree for occurances of the old URL. It appears that there's 3 items storing the URL in the .csprog file, one of which is the culprit (can't recall right now which), but they are: <PublicUrl> <InstallUrl> <UpdateUrl> I think it's the InstallUrl that holds onto the old setting. I have to manually edit the project file with a text editor to get the darn thing to publish and behave properly. Am I doing something wrong or is this a bug? Is there a better way to do this? TIA.

    - Click-Once deployed app - need to change .config.deploy file I have a click-once deployed application that I need to change which web services it references *AFTER* deployment. When I change my deployed xxxxxx.config.deploy file on the server so that it references a different set of web services, the application continues to access the old webservices. Before you think you have the answer, let me tell you what I've done (this has been a problem for about a year now, but we're determined to get it resolved): I manually edited the .config.deploy file to change the URLs of the web services (original deployment pointed to a dev instance of the web services), I'm changing them to point to the testing/staging environment web services, then will change to point to production as the compiled deployment moves it's way torwards acceptance and finally production. When I edited the file, I expected the app to refuse to run, but it didn't. It ran without complaining (unlike what happens if I edit the .application file without re-signing it). I even removed the .config.deploy file and still no complaints and still it used the dev web services. Yes, I re-signed the manifest with mageui.exe. I edited the .cong.deploy file, but it appears the app is not using the .config.deploy file at all. In the source code, there's a Settings.Designer.cs file that's generated based on my app.config and in there is hard-coded the values of the web service URLs as they are at the time of publish from Visual Studio to the development server. Our deployment process has always been with web apps and this is new territory for us (in spite of the fact that this app has been around for about a year now... it's still our first one and has recently gone to production). Our deployment procedures are as follows: 1. Compile and then the developer deploys to dev. then developer asks admins to move it to staging (having admins changing the connection strings and such in the web.config file). Developers don't have write access to the staging envrionment. 2. Testers test application in the staging environment. If all goes well, developer asks admins to move app from staging to production, again making necessary changes to the web.config file. Developers don't have access to the production environment. On subsequent updates, the web.config file is just not copied, unless there's anything new in it, then the admins are asked to add the new items to the existing web.config files in each environment. This process has worked well since the 1990's, but now with click-once deployed apps, that procedure isn't working because we can't find a way to make changes to the .config.deploy file without having to publish from Visual Studio 3 seperate times, making the changes from within Visual Studio for each environment. In addition, we can't move a single deployment from environment to environment. We have to make 3 seperate builds, making it impossible to prove that what went to production was truly what was tested. Any help would be GREATLY appreciated!!! Tag: Binding navigator Tag: 116923

    - 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: Binding navigator 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: Binding navigator 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: Binding navigator 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: Binding navigator 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?

    - 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: Binding navigator Tag: 116869

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.

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?

GroupBox gbx = new GroupBox(); //gbx.AutoSize = true; gbx.Name = "gbx" + pi.Name; gbx.Text = pi.Name; gbx.Padding = new Padding(2, 5, 2, 2); panel.Controls.Add(gbx); TableLayoutPanel tlp = new TableLayoutPanel(); tlp.ColumnCount = (int)Math.Floor(Math.Sqrt(names.Length)); tlp.Dock = DockStyle.Fill; tlp.Padding = new Padding(1); //int maxRBLength = 0; foreach (string name in names) { RadioButton rb = new RadioButton(); rb.Name = "rb" + name; rb.Text = name; rb.AutoSize = true; rb.Margin = new Padding(0, 0, 0, 0); //if (rb.Width > maxRBLength) maxRBLength = rb.Width; tlp.Controls.Add(rb); } gbx.Controls.Add(tlp); Thanks SG Tag: Binding navigator Tag: 116837

    - 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. Are there any tips to make app response better for user? Thanks Regards Tag: Binding navigator Tag: 116822

    - Bootmgr. missing Hey all you fine technological geniuses! I have seen some of you having some problem as I have encountered the last week. When starting up the computer says: 'Bootmgr. missing - press ctrl.-alt-delete to restart'. I think I might have tried everything you have suggested and more to it, but the problem still remains - do anyone have a new solution to my problem - it starts to aggrevate me! By the why - I'm running Vista home premium. -- Midtgaard Tag: Binding navigator Tag: 116820

    - Upgrade to Vista Ultimate broke VS 2008 I had Vista Home Premium with VS 2008 - worked just great. Upgraded to Vista Ultimate - now with a Windows App the following happens: 1. Try to open Form1 in designers mode (new app or existing app), error = "The service Microsoft.VisualStudio.Shell.Interop.ISelectionContainer already exists in the service container". 2. Compile app (new or existing), build error = ".NET Framework 2.0 update not found. The win32manifest will not be embedded" Tag: Binding navigator Tag: 116815

    - ClickOnce Updates from a Different Publish Server Hi, I'm currently using ClickOnce to deploy an application written in Visual C# 2005. The client has it installed already. I'm wondering if there is a way to change the client to point to a different publish server (http://66.x.x.x/app) to download updates without uninstalling and installing the client. Thanks.

    - 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: Binding navigator 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: Binding navigator 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: Binding navigator Tag: 116791

Hi,

I have a binding navigator which has 1 binding source bind to it.
I have some textboxes bind to the binding navigator.I have some validations
to be done at lost focus events of all the text boxes.

the system is getting hang up if any one is trying to give invalid
input,rather than what is supposed to be prompted (I have those validations
written in lost focus event of those textboxes) .

Can any one help me in this regard.
