    - MDI child icon problem Hi, I'm working with VS.NET2005 and building MDI application. All of my child forms have to be maximized. Problem is that when they are maximized before showing them, default form icon is shown, not the one that I set. I also disabled minimize/maximize buttons, but the restore down button is still enabled. Icon and maxmize(restore) button get to normal if I resize parent form, but that is not solution. Any ideas how to handle this? Tag: Resource file Tag: 103046

    - Serial no check - setup & deployment project Hi techies I have a registration form to download my application. During this registration i generate serial no for that user and i am sending to user by e-mail The download contains my application deployed in .net setup & deployment project. During installation the user has to give the serial no which i sent to him by mail. If it is a valid serial then i should allow them to install otherwise not. In .net customer information dialog with serial number is available. But i do not understand the goal of this dialog. will my scenario sit in this dialog. Or we have another option of Register user dialog which is only to call an exe not for validation, will it be useful for me. But goal is to stop the installation when they give wrong serial no. Suggestions please Tag: Resource file Tag: 103038

    - ASP.NET vs Windows Forms for building client application I kind of understand the ASP.NET architecture in terms of building web pages with embedded server controls, where the .aspx is run on the client and the .aspx.cs runs on the server. But what if I want to build an ASP.NET based application that is to be run entirely on a client (all files hosted on the client and run on the same client)? What would that client need to run it? I want to write an application that can be run standalone on a PC (not hosted on a web server and accessed from a PC), which uses web technology like javascript and Ajax, while also being able to code the primary logic in C#. I have the choice of a windows forms rich client application which uses a WebBrowser control, or a native ASP.NET application. But I'm not sure the latter is even feasible for being deployed and run standalone on a PC - would it need IIS and .NET framework installed, and even more? Tag: Resource file Tag: 103035

    - HELP: drawing on winform from native Win32 paint crash app.... Hi, I have an application written in C# which will use some custom libraries written in native C++. To bridge between the C# application layer and the native C++ library side, I created an IJW assembly using mixed mode C++/CLI and native C++. From the C# application side, I need to pass a window handle to the custom library so that inside this library, it will do some drawing on this screen. So, I from the C# application passed a Control.Handle to the library. However, the moment the custom library tries to draw something on this screen(I used SPY++ to trace it), it will crash when WM_PAINT is called. The error is AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. Why does this happen? How do I solve it ?. I have even tried creating a window on the IJW library using CreateWindow("STATIC"...) and pass this to the custom library for it to use but the problem still occurs. If this window is hidden. the app will not crash. It will only crash the moment this window is shown. Anyone could help me on this? Thanks!!!! John Tag: Resource file Tag: 103033

    - Countries, States, and DataGridViews Hi all, I'm trying to get two columns in a DataGridView to talk to each other. One of the columns contains countries. The other contains locales (states, provinces, territories, etc.). Both of these columns are set up as DataGridViewComboBoxColumns. I want it to work so that, if the user selects a country, the locale combo box in the adjacent cell will be auto-filtered to show only locales for the selected country. Similarly, if the user selects a locale first, the appropriate country should be auto-selected. Is this possible? If so, how should it be done? I thought maybe I could add a WHERE clause to the Locale SELECT query, but I couldn't figure out how to test it against the value of the neighboring cell (tried to create a @Country parameter but got nowhere). Also not sure if the combo boxes in a single column can even have unique filters. Another thought was that I may need to write event handlers for the combo boxes that apply filters. But this still requires that you can have unique filters for the combo boxes in a column. Any help on this much appreciated. Thanks, -Dan Tag: Resource file Tag: 103031

    - 0 is not a valid handle Hello, I have a windows forms app built with vb.net, framework v. .1.1, sql server 2k5 backend, and uses crystal reports for .net. The app runs on a terminal server with no more than five users. The problem is about once every other day, when one of the users tries to print a report they receive a message box with the error '0 is not a valid handle' Once this happens the server must be restarted, because everyone else will receive the same error until the server is restarted.

    - Combox Autocomplete, but read-only I'm working with C# in Visual Studio 2005. I have a combobox with AutoCompleteSource = ListItems and DropDownStyle = DropDown. I want users to be able to type in the combobox and the control to autocomplete (Append AutoCompleteMode), but have their options limited to the control's ListItems. Right now the autocomplete works fine, but they can type anything that isn't in the list. Is there an easy way to set the control to do this or am I going to have to write code to verify what was typed during TextUpdate or another event? Tag: Resource file Tag: 103027

    - 2nd form on top I'm trying to do something similar to what outlook does with its task reminders and haven't been able to accomplish this the way I want. When a reminder is due, it pops that window up. And it stays on top but it's deactivated and the Outlook window is the active window. And if you click on the title bar for outlook, it'll pull it to the front. So I've tried various mechanisms to accomplish this such as using topmost and then unsetting it. The best I've gotten so far is setting the child window's owner temporarily to the main form. And then setting the child window's owner to null after I've activated the main form. The problem with this is that it does some funky things down in the taskbar. As soon as I set the owner to the current window, it will remove it from the taskbar. Does anybody know of a way to accomplish what I'm trying to do without this odd behavior? Lance Johnson Tag: Resource file Tag: 103021

    - DataGridView loses key up events? Hi all I have a data grid view, and I also have a key up event which watches only for the F5 key. It works fine, except that after the initial press, the datagridview ignores subsequent key up events until I move the selection to another cell. Its very odd, because i set SuppressKeyPress and Handled to true, and I get the same behavior if the Form is handling the event instead. Any ideas? Thanks Andy Tag: Resource file Tag: 103019

    - Use of Program.cs I'm finally getting up to speed on VS 2005 and see that there is now a class named Program that contains the main entry point for Windows Forms applications. Yes, I understand that this is something that VS creates for us and that we are not *required* to use it as is. My question: Are many of you who are writing non trivial Windows Forms applications keeping this Program.cs file as generated by VS? Are you using it "as is" or do you throw other things in there? If so, what else do you add to Program.cs? (just wondering what most developers think of this change and how you are using it). Thanks. Tag: Resource file Tag: 103014

    - multiple threads with a form Hi, I have a form in main thread. I also use a 2nd thread as datalayer for dataset <--> SQL Server. I have some controls that binds with the dataset. When the 2nd thread modifies the dataset, it will trigger events of a control that binds to the dataset. My question is if the event run on the 2nd thread or the main thread? When I step in, I check Me.InvokeRequired and it's True. Does that mean the event run on the 2nd (background) thread? Thanks in advance. Li Tag: Resource file Tag: 103005

    - Slow drawing speed of WinForms (esp via COM interop) Hi, Has anybody experienced severe slow-down with the drawing speed of WinForms? It's not fast at the best of time, but the particular scenario I am having problems with is via COM interop and Excel. The structure is: Excel VBA macro | V instantiate and call a COM wrapper class exposed by my assembly using ComVisible(true) | V Wrapper class instantiates the WinForm and displays it The forms don't do anything special, they contain maybe 10-20 controls, including one or two grids, but you can sit there and watch them paint themselves control-by-control. I am using data binding, if that helps. Any help to fix this will be very gratefully received, but even if you have experienced something similar please reply so that I know I am not alone! -- Phil Tag: Resource file Tag: 103004

    - Regarding updating one comboBox from another: what order is best for clearing and updating the second box? I am having an issue with graphical corruption upon re-selecting a combobox which upon 'selected index change' event should list file names in that folder in a separate combobox. Here is the code: private void comboBox2_SelectedIndexChanged(object sender, EventArgs e) { IniFile INI = new IniFile(@"c:\\data\TM.ini"); string MisFileDir = INI.IniReadValue("Main", "MisFileDir"); //MessageBox.Show(MisFileDir + @"\" + this.comboBox2.Text + @"\"); DirectoryInfo dir = new DirectoryInfo(MisFileDir + @"\" + this.comboBox2.Text + @"\"); FileInfo[] misfiles = dir.GetFiles(); comboBox1.Items.Clear(); comboBox1.BeginUpdate(); foreach (FileInfo f in misfiles) { comboBox1.Items.Add(f.Name); } comboBox1.Update(); } As you can see, I'm using an INI file class that utilizes a kernel32.dll function to read from the INI. (see this article - http://www.codeproject.com/csharp/cs_ini.asp?df=100&forumid=3467&exp=...) This part works perfectly well. And upon the first selection of comboBox2 , comboBox1 usually updates fine with a list of files in the given folder. The problem comes primarily when I select a different index in comboBox2, the comboBox1 imagery corrupts. I can still see the indexes, but the text of that comboBox is invisible or garbled. [yes i should have used the opposite numbers for their names! sorry for confusion:)] Question: My question is, am I updating the comboBox1 items in the appropriate order? What is the best way to clear a combobox and re-add items to it? Here is an image of the corruption: http://seow.trianglesimsociety.org/corruptedimage.JPG Thanks for any suggestions you may be able to provide. MurdockSE Tag: Resource file Tag: 102999

    - Toolbar question Besides querying the Text property, how do you find out which button on the toolbar has been clicked? The Name property doesn't appear in the code window, but only appears in the design mode. The problem is that I have added a lot of spaces to the left of the label of one of my buttons. The actual label text I have entered in the design mode is " Exit Map". When I query this: else if (e.Button.Text.Trim() == "Exit Map") { this.Dispose(); this.Close(); } The code skips this condition altogether. For the other labels, it enters the construct as it should. I am a bit confused. Tag: Resource file Tag: 102998

    - Slow Startup Time for NTD Winforms Hi, We are using NTD to deploy our smart client .NET app over the web. When the application starts up on a client, there are numerous HTTP requests for files such as: "application.resources", "application.resources.dll", "application.resources.exe", "bin/application.resources", etc. These requests all returned a HTTP 404 not found. I have been trying to find a way to eliminate these requests. I currently have in place a workaround that basically places an empty file with the first name requested for each assembly. This reduces the number of requests from around 32 per assembly to 2 per assembly. I would still like to get rid of them altogether, if possible. I have read here and there others who have experienced this problem. One of the solutions I came across was to use the following code: Thread.CurrentThread.CurrentUICulture = System.Globalization.CultureInfo.InvariantCulture; I tried putting this line as the first line in my Sub Main() but the initial requests did not subside. I think that maybe I am not using it correctly, but I have been unable to find more information about this. Any help of how to eliminate these requests would be greatly appreciated.

    - Enter and Leave events I am trying to understand Enter and Leave events for a user control. I am using Visual Studio 2005, using VB, for a Windows Forms application. I am showing and hiding (by changing visible property) user controls on my main form (within a panel) based on NavBar links being clicked on. I put code in the Enter and Leave events to simply show a message. Here's what happens... The first time the contol is shown, the Enter event fires. The first time I click on another NavBarItem, the Leave event fires. However, the control associated with the clicked on NavBarItem doesn't show. After that, the Enter and Leave events no longer fire when control's visibility is changed. So, I guess it's not the change in visibility that fires these events. Then what does cause them to fire? What if I want to check for certain conditions being met before I allow a user control to be hidden (Visible=False) and, if they're not met, I disallow the change (i.e. keep it visible and don't show the new user control)?

    - Data Source drag/drop not allowed on inherited form In VS 2005 I have a base form that is designed to be inherited by many other forms within an application. This base form contains a tab control with two tab pages, among several other controls. The second tab page (lets call it TabPage2) has the Modifiers property set to Protected so that any inherited forms can add controls to the tab. When I create an inherited form, I can drag new controls from the toolbar to TabPage2 without a problem. However, what I would really like to do is drag a table (or selected fields) from the Data Sources pane so that the data bound form fields are created automatically. That would be a wonderful convenience. The only problem is, when I try to drag a field over TabPage2, I get the "not allowed" cursor symbol and the drop operation does nothing. As another point of interest, this base form was brought over from a VS 2003 project that is being converted and upgraded using VS 2005. I'm not sure if the version change is affecting the outcome or not. The base form and its related code are a little complex. In an effort to isolate the problem, I started a new project and created a very simple form with the same tab control design. When I inherited this simple base form and tried to drag from the Data Source window, it worked perfectly. Very mysterious. Something in the old base form is preventing the drag and drop operation from working (although not for regular toolbar controls). Any ideas on how to isolate or debug this? Thanks. -- Jo-Anne V Tag: Resource file Tag: 102978

    - Double Buffer panel within SplitContainer to avoid TreeView flicke I have a treeview derived control placed within Panel2 of a SplitContainer control on a form. The TreeView flickers during updates so I set the DoubleBuffered attribute to true (in the constructor of my class derived from TreeView). It still flickers so I was thinking that it could be that DoubleBuffered also needs to be set within the parent panel that contains this TreeView derived control. However, in this case, the parent is a panel that belongs to a SplitContainer. Of course, I can't directly set the DoubleBuffered property of Panel2 and I was wondering if there is some other way to do this or if I'm on the wrong track altogether. Also, I'm using C++/CLI and the tree view nodes are user-drawn, does this for any reason automatically rule out the use of double buffering on the related tree view?

The code I use is: Assembly assem = this.GetType().Assembly; Stream streamTransPic = assem.GetManifestResourceStream("MyProject.images.transPic.gif"); transPic = System.Drawing.Image.FromStream(streamTransPic); It is rendered with Graphics.DrawImage method in gObj.DrawImage (transPic, rect); where gObj is an instance of Graphics and rect has already been defined.

Any help would be most appreciated. Regards Rob Tag: Resource file Tag: 102932

    - access the calling user's config info from a dll? Hi, I am using C#. My WinForm project has a config file created by VS2005 containing some user scoped properties. It has setup as the config file as follows: <userSettings> <MyNameSpace.Properties.Settings> <setting name="MyProperty" serializeAs="String"> <value>"aaa"</value> </setting> </MyNameSpace.Properties.Settings> </userSettings> I can easily access the property value in a type-safe manner in my WinForm via: Properties.Settings settings = MyNameSpace.Properties.Settings.Default; MessageBox.Show(settings.MyProperty); My WinForm uses some BO's from a dll. How can I access the config properties from within the dll? The class which contains the property specification is marked internal to the WinForm exe. I have read the helptext regarding ApplicationSettingBase and ConfigurationManager classes. These are both new with .Net 2.0, so they most be both current technologies. Neither sections of helptext refer to the other. I can't understand what job each of them are trying to do, or how they relate to each other. If one wants to access the calling user's config info from a dll, which facility should I be using? thanks Barry Mossman Tag: Resource file Tag: 102931

    - crystal reports Why would using crystal reports run fine from one pc but not anpther? I disabled filewalls, had admin rights, selected the install prerequsits. I get a log in screen that won't accept any login. Logged in as the same user from another pc, it works fine. It seems on the pc that worked a warning run app screen came up that didn't come up on the one that failed. This makes me think something is stopping the crystal reports viewer form installing correctly?? the viewer does come up though, but it cant connect to the database. Tag: Resource file Tag: 102930

    - Moving childs within a MDI parent area Hi, I am developing an application using VB.net (2005) and I would like to know if there is a way for allowing MDI childs just to move within the borders of the MDI parent. Now the MDI childs are able to dissapear for a part out of the screen, and then scrollbars appear. I would like to prevent that. I've tested a little with the Move event, by changing back the MDI childs position at a certain position, but this results in a nasty flickering effect. Is there anyone who knows how to handle this problem ? Thx, FrÃ©. Tag: Resource file Tag: 102929

    - Using Microsoft Chart Control in dotnet I am trying to use the Microsoft Chart Control COM component in dotnet 2.0 but keep getting "class not registered" exceptions when I try to run the code. I have done the following so far to try and get around this issue: - registered mschart20.ocx using "regsvr32 mschrt20.ocx" - registered AxInterop.MSChart20Lib.dll using regasm - registered Interop.MSChart20Lib.dll using regasm - reinstalled Office Web Components 2003 Unfortunately, none of these has made any difference. More or less, I am doing the following with my code: - create new project - add Microsoft Chart Control 6 reference (listed in COM object list) - drag a Microsoft Chart Control 6.0 (SP4)(OLEDB) to my form - Try to run the code - class not registered exception is thrown every time Does anyone have any ideas? Using DotNet 2.0 with VS 2005 on Windows XP 64-bit currently. Bob Dankert Tag: Resource file Tag: 102928

    - How to make asynchronous call ? Hi all, First, I use C# with the .NET Framework 2.0. I would like in the method OnButtonClick, call the method A.DoSomething but in a way that executes after OnButtonClick has finished its execution. I am looking for something like a PostMessage in Win32 in fact. How can I do that in C# ? Class A { // may be inheriting from Form too void DoSomething() { } } Class B : Form { void OnButtonClick() // for example { // call A.DoSomething but do not execute yet return; // now it is the time that DoSomething must execute } } Thank, Laurent Tag: Resource file Tag: 102927

    - .Net: File copy control Hi, I'm looking for a Windows Forms Control to copy files and direcotries between two directories. |-----| |-----| | | <- | | | | | | | | -> | | |-----| |-----| What I've found up to now: System.Windows.Forms.OpenFileDialog System.Windows.Forms.SaveFileDialog System.Windows.Forms.ForlderBrowserDialog As the names state these are dialogs and not simple controls, and thus cannot be arranged like the schema shown above. Microsoft.VisualBasic.Compatibility.VB6.DirListBox Microsoft.VisualBasic.Compatibility.VB6.DriveListBox Microsoft.VisualBasic.Compatibility.VB6.FileListBox Is it a good idea to use VisualBasic controls in a C# application? These controls don't look really nice and they don't really satisfy the schema shown above (z.B. FileListBox only shows files, no directories.). http://www.windowsforms.net/ControlGallery/default.aspx?Category=6&tabindex=5 http://www.codeproject.com/ These sites have some interessting controls. Can someone recomment one of these controls? Or dissuade from one? The controls should be usable in a professional commercial application (license, stability, internationalization, use system icons,...). Other recommendations? Thanks. -Puce Tag: Resource file Tag: 102926
