    - Hi Hi, I have made setup project in my solution. I would like to include Windows installer 3.1 (since it is needed for installations) and runtime of Framework 2.0. How to do include runtime of Framework and and Windows Installer in setup package? I don't want when installing my program to connect to internet and download this components. .NET Framework Launch Condition In help says: if you are distributing your application on CD-ROM, you should include the redistributable file on the CD and change the InstallUrl property to a relative file path. If my solution is in folder C:\MySolution , what should I write in InstallUrl property, so that it is a relative path. Thanks in advance, John Tag: Fereshing an open form Tag: 99686

    - ClickOnce Install returns XML I have deployed an application with ClickOnce Publish wizard to a web site. But when I click web page Install button the web server just returns the content of the .application file as XML to the browser on my own client. I made a quick try on two other clients and it seems that they are capable to interpret the web page correct ..... it is really a strange issue. trying the following command line in cmd.exe: rundll32.exe dfshim.dll,ShOpenVerbApplication http://www.xxxx.com/ConfigurationTest/ConfigurationTest.application Note: replace "http://www.xxx.com/ConfigurationTest/ConfigurationTest.application" with your clickonce application's deploy manifest URL. With this we can determine if the client side's dfshim.dll works well with the *.application files. However, even with dfshim.dll information, it is still hard for us to troubleshoot out this issue. Maybe we need re-install the Win2000 machine... This works.... Ok, I think you may first download the *.application file to the local disk, then double click this application file to do a test. Once your file association is correct, it should display the clickonce checking dialog. This works... I think there is more of a problem here. I am getting the same results on windows xp pro machines. I tried it on 3 different machines. The only machine that is able to install the application from the publish.htm is windows 2003 server that the application was publish from. But not an any (at least the 4 i've tried) xp pro machine... Ideas? Tag: Fereshing an open form Tag: 99684

    - window size and position - FixedToolWindow Hi, I'm using C# in VS2003 with .Net Framework 1.1 sp1 installed. I have a tool window that is sized and positioned to cover a certain part of another window. On my desktop machine this works perfectly however when I run it on my laptop the window is neither the correct size or position. If I close it and open it again it is moved slightly dwon and to the right each time. The size seemingly has nothing to do with the size the window is set too, all the controls appear in the correct place and size though. So I thought I must be using a different version of the framework on both machines so I spent ages making sure everything was the same version and as far as I can tell they are. If I take the version compiled on the laptop and run it on the desktop it works so it would appear that it is something to do with versions rather than the code but I'm clueless. My window uses FixedToolWindow and I've noticed that even at design time on the laptop its not showing a short title bar like a tool window should have. Has anyone come across this before? Please help!! I'm so annoyed because I thought I'd do this project in C# because it would be quick and easy but now I'm left wondering why if I cant give my client something that works identically on different machines why I didnt just do it in C++. I'm sure I wouldnt be having this problem then! Regards Josh Tag: Fereshing an open form Tag: 99678

    - Blank DataGrid Hello: This must be quite simple! But I couldnt figure out whats wrong: I have this following code, and I still see a blank datagrid: Imports System.Data Imports System.Data.SqlClient Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim conn As New SqlConnection("****") Dim da As New SqlDataAdapter("Select * from tblNote where CDID = 55", conn) Dim ds As New DataSet Dim dt As New DataTable da.Fill(ds) If (ds.Tables(0).Rows.Count > 100) Then dt = Get100Rows(ds.Tables(0)) End If dt.AcceptChanges() Dim dv As New DataView(dt) Try DataGridView1.DataSource = dv Catch ex As Exception MessageBox.Show(ex.Message) End Try End Sub Private Function Get100Rows(ByRef dt As DataTable) As DataTable Dim dt1 As New DataTable Dim i As Integer For i = 0 To 99 dt1.ImportRow(dt.Rows(i)) Next dt1.AcceptChanges() Get100Rows = dt1 End Function End Class I can see that the DataTable dt has 1000 rows. The datagrid does get populated if I were to have Tables(0) of the DataSet ds as the DataSource. TIA. Skandy Tag: Fereshing an open form Tag: 99671

    - How to catch clicks on contained controls in the form. I would like to capture, in my form, any mouse clicks on controls contained in the form. I know I can do this using a mouse hook, but that has a few problems with catching clicks on dialogs the form owns that I have not been able to work out. I want to catch the click, so I can lock the data source, and then let the click go on its merry old way. Any simple solutions that I am overlooking?

    - ClosingEventArgs 'Cancel' member already set to true by framework I'm having a difficult time trying to track this issue down. Hopefully, someone might be able to share some insight. I have a situation where a form is not closed when I explicitly call Close() on it. As part of trying to debug this problem, I overrode the "OnClosing" method (and OnFormClosing, too) and noticed that the 'Cancel' member of the ClosingEventArgs parameter is already set to true upon entering and before I explicitly forward the call to base.OnClosing(). If I force Cancel to be false, then the form will close without a problem. Does anyone have an idea why the framework is setting Cancel to true? It is difficult to reproduce the problem with a small example. What I can tell you is that the form in question is a TopLevel (and TopMost) form with the Owner property set to an MDI child. The TopLevel form has a splitter control that houses two child forms... however, I remove the splitter control from the form before I call Close() (the form then contains no child controls). This is the point where the form fails to close. Tag: Fereshing an open form Tag: 99657

    - set a NotifyIcon to "Always Show" Hi, I've got an application that, when minimized, displays a NotifyIcon in the System Tray. Is there anyway to get that icon to be set to "Always Show" in WinXP? What I mean is, XP allows the user to classify icons in the system tray as "Hide when inactive" (default), "Always Show" and "Always Hide". I would like my application to be set to "Always Show". Is that possible? Thanks, Doug Tag: Fereshing an open form Tag: 99652

    - Accesing form's components in design time Hi, I need to access all components of a winform (controls, and any other component which does not inherit from System.Windows.Forms.Control) both in design and run time. In design time I access the components and iterate through them using form's Component property, but in run time this property is null. I can access all the controls using form's Controls property, but I need to access also the other components such as ContextMenu, ToolTips... which are not Controls. How can I get this?

    - Exception in InitializeComponent On my test run-time machine my application is generating a "... has encountered a problem and needs to close..." exception from WITHIN the InitializeComponent section of my main form. This is curious since if I do a full install on my development machine it runs without a problem. This has happened to be before and I traced it that time to a form control using a font which was not on the target machine (why can't it just use a default font in this case??), but I've double checked all fonts used this time, and all seems to be ok. So my question is in general: how can I find out where it's going down in cases such as this? The "report contents" generated by the exception seem to give me little clue.

    - PLS HELP:Managing events Hi, I'm developing a usercontrol which has an event SelectedValueChanged. Below is the simple version of what i have: //------------------------------ class SelectedValueChangedArgs: EventArgs { object m_oValue; public SelectedValueChangedArgs(object oValue) { m_oValue = oValue; } public object Value {get{return m_oValue;}} } //-- public delegate SelectedValueChangedHandler(object sender, SelectedValueChangedArgs e); //-- public MyControl{ public SelectedValueChangedHandler SelectedValueChanged; } //----------------------------------- The problem is that i have to make sure that any event handler added to that event is added only once, so i should use it like this: SelectedValueChangedHandler h = new SelectedValueChangedHandler(SomehandlerFundction); myControl.SelectedValueChanged -= h; myControl.SelectedValueChanged += h; But the problem is that i can't control all 30 developers in the company and i ended up spending the whole weekend cleaning up after them (adding -= to make sure the handler is not added second time somewhere). So now i'm thinking of making the event protected and creating a function which will be adding a handler: // -------- CODE --------- class MyControl{ <...> public void AddSelectedValueChagedHandler(SelectedValueChangedHandler h) { SelectedValueChanged -= h; SelectedValueChanged +- h; } } ///----------------------- Is there a standard way/pattern to make my life easier here? :) I think i've seen somewhere that you can override -=/+- for an event or something like that. I still would like to go with event instead of a wrapper function as above. Any ideas/comments are HIGHLY APPRECIATED!!! Thank you in advance, MuZZy Tag: Fereshing an open form Tag: 99621

I have two methods that loop across and either enable or disable all but two of the controls. I am using SuspendLayout and ResumeLayout at the form level, but so far I don't see any real improvement because of it. Is there a better way to handle disabling / enabling large volumes of controls? I wish I could buffer the form paint surface and have it render off screen, then just paint the one image after the controls have all completed their painting. Thoughts appreciated.

    - Trying to "display" control characters in a text box I have a barcode scanner which uses a "keyboard wedge" program so that the data it scans comes through as if it was typed on a keyboard. I am trying to have the data in the barcode be displayed in a text box. I know that there are certain control characters embedded in the data that I want to display substitutions for in the text box, for instance I want to replace ASCII character 04 with the string "<EOT>". I have tried doing a simple replace in the TextChanged event, but it appears that the Textbox Control strips out the control characters as they come in. I also tried catching the "keystrokes" using the KeyUp event, but that seems to have done something (and I can't figure out what) with some of the control characters and added other characters that are not in the data. Does anyone have any suggestions as to how I can accomplish this? I know what the data encoded in the barcode is, and I can verify that the scanner is reading it properly - I just can't get it into a VB.Net text box properly.

    - TimeSpan column (or something similar) in a DataGridView I'm looking for an article or maybe some free advice (yes, I've been searching around...) I am to implement a time card in a DataGridView bound to a SQL Server 2005 table. There are DateTime columns (time in, time out) and columns with elapsed time in them (e.g. lunch) which _could_ be done with TimeSpans (I think). How best to go about this? 1) Which database type would best represent the elapsed time? (datetime, integer representing # of minutes, or ...?) 2) What corresponding built-in .net class or custom type would go with that on the client? 3) Once I've got the underlying type nailed down I can develop the custom column myself, but if anyone's done this before I ain't too proud to beg for sample code Tag: Fereshing an open form Tag: 99570

    - Monitoring user interaction with the axWebBrowser control Hi all, I have a vs2005 winform that host the activex axWebBrowser control. I would like to monitor how long a user spends on a site viewed in the web browser control, In the web world this would usually be done on the web server by using some sort of caching or session objects. Is it possible to determine how long a user spends on a given site using the web browser control? Any replies, links, articles, or books on the above subject would be greatly appreciated.

    - Exception when use MessageBox.Show in prog with long path All - I haven't come across this issue elsewhere, or in a search within this newsgroup. Perhaps someone here has come across it... In both 1.1 (SP1) and 2.0, when using MessageBox.Show in a simple Windows app (only shows the messagebox), and with the .EXE file sitting at a location where its total path length is greater than 128 characters, the EXE doesn't work. In .NET 1.1, a NullReferenceException is thrown inside MessageBox.ShowCore. In .NET 2.0, nothing at all happens (the app just exits). Even with all exceptions set to be trapped in the debugger, there's no exception at all. If the same .exe is moved to a higher-level folder, such that its total path is less than 128 chars, it works fine. Any clues? Thanks, Jeff Tag: Fereshing an open form Tag: 99559

    - Merging ActiveX Control Hi Every body, I am currently working in aproject where I am stuck in merging an ActiveX control (*.ocx) file into a managed Class Library (*.dll). I want to hide the ActiveX Control in this managed Dll, so that even when things are deployed I don't wanna see two files, but only 1 file which is the dll, and it would contain within it, the other ocx file. Is this possible? If yes, then how can I do something like this, I tried to use ILMerge, but it sounds that it doesn't do what I wanted to have..

    - newbie: multiple panels in form Hi, I'm writing an application that makes use of multiple panels (that contain specific components), but shows only one to the user at a time (which one depends on user interaction in a toolbar). Now, as all panels have the same size and the same position in the form, it's quite annoying to work with (esp. if you want to change a thing in the 'lowest' of the overlapping panels). so, as a newbie, I'd better ask if there is any better way to handle this or a Visual Studio feature that makes life easier?

    - PropertyGrid bug with Permissions I think I'm encountering a bug in the PropertyGrid control when I use it in conjunction with Permissions. I get an IndexOutOfRangeException whenever the grid updates itself (for instance, when I set SelectedObject, or call Refresh()). Here's the stack trace from the test application I put together (code below). I also get this stack trace in my main application if I call Refresh() on the PropertyGrid before the form it is on has been shown, and before I've assigned a SelectedObject. ----- at System.Windows.Forms.PropertyGrid.RefreshProperties(Boolean clearCached) at System.Windows.Forms.PropertyGrid.Refresh(Boolean clearCached) at System.Windows.Forms.PropertyGrid.set_SelectedObjects(Object[] value) at System.Windows.Forms.PropertyGrid.set_SelectedObject(Object value) [My Code] ----- Here's the stack trace I get from my main application if I don't set the SelectedObject until after the form containing the PropertyGrid is displayed (it is instead set in response to a mouse click on another control). ----- at System.Windows.Forms.PropertyGrid.UpdatePropertiesViewTabVisibility() at System.Windows.Forms.PropertyGrid.ShowEventsButton(Boolean value) at System.Windows.Forms.PropertyGrid.set_SelectedObjects(Object[] value) at System.Windows.Forms.PropertyGrid.set_SelectedObject(Object value) [My Code] ----- The code for the test application that I mentioned: ----- using System; using System.Drawing; using System.Drawing.Printing; using System.Windows.Forms; using System.Security.Permissions; namespace PropertyGridTest { public class Form1 : Form { private PropertyGrid PropertyGrid1; public Form1() { PropertyGrid1 = new PropertyGrid(); SuspendLayout(); PropertyGrid1.Dock = DockStyle.Fill; PropertyGrid1.SelectedObject = PropertyGrid1; // exception ClientSize = new Size(292, 273); Controls.Add(PropertyGrid1); ResumeLayout(false); } [STAThread] static void Main() { // FileIOPermission Permission = new FileIOPermission(FileIOPermissionAccess.Read,"C:\\temp"); // FileIOPermission Permission = new FileIOPermission(FileIOPermissionAccess.AllAccess,"C:\\temp"); // PrintingPermission Permission = new PrintingPermission(PrintingPermissionLevel.SafePrinting); EnvironmentPermission Permission = new EnvironmentPermission(EnvironmentPermissionAccess.AllAccess, "HKEY_CURRENT_USER"); Permission.Deny(); Application.Run(new Form1()); } } } ----- This problem seems to happen no matter which permission I deny or how that permission is configured. The exact same thing happens with any of those commented out permissions. However, the problem goes away completely if you just comment out the Permission.Deny() line. Any ideas, help, or work-arounds would be very much appreciated. Thanks! Tag: Fereshing an open form Tag: 99553

    - Printing HTML from Window Forms What's the best way to print an html document generated in a Windows forms application? IE (WebBrowser control) works pretty well; with some effort to use a print template, you can control margins, headers, footers, and get print preview. The 'gotcha' is that (as best I can tell), there's no good way to specify the printer that you want to print to. I tried calling the windows api to set the default printer, and this works sometimes, but my application needs to send different print jobs to different printers, and the selections sometimes 'step on' each other when you switch the default printer. I also looked at the ReportViewer, but I could not find a way to get it to render html. Am I missing something? Surely there's a good way to print html from Windows forms.

    - Winform with HelpProvider control loses focus. Hello everybody. I have a Winform with a HelpProvider control. Everything works as expected when I push the F1 key (I see the help window with my .chm help file). However, when I close the help window, the focus doesn't go back to the application's main form. It's not a big problem, but it's very annoying for the user, who has to Alt+tab to the application or click into it. If you try launching the help window with Internet Explorer, for example, after closing the help the focus goes back to the main window. Is there a way to obtain that behavior in .NET?

    - Using WebBrowser to open office documents inside a Windows Forms Form Using Visual Studio.Net 2005 Team Edition for Software Developers on a Windows XP machine. Microsoft Support article 304662, dated 1/10/2006 shows how to use the WebBrowser control to open word/excel documents inside a Form. http://support.microsoft.com/?id=304662 The basic code works - I can put a WebBrowser control into a form and then call webBrowser1.Navigate( url ) and if 'url' is a .doc or a .xls file, word/excel open and display the document. Very cool! However, the article goes on to say that you can then get ahold of the automation object from within the "NavigateComplete2" event handler (see steps 7 and 8 in the article). However, the webBrowser1 object created by the designer does not appear to have a 'NavigateComplete2' method (event) and I can find no help for the 'AxSHDocVw' class referenced in the parameter list for the NavigateComplete2 event handler code. The fact that the article's code has a WebBrowser instance named 'axWebBrowser1' leads me to believe that I do not have the same WebBrowser class used in the article. The article is dated 1/10/06, so it appears very current and specifically mentions that it applies to .Net 2005. Has anyone gotten this to work? thanks! john Tag: Fereshing an open form Tag: 99545

    - Cannot find assembly error I've spent half today trying to figure this out to no avail. I have a solution, using remoting, with 13 projects. The assemblies are using a strong name key and things were working fine until today when I tried to change the version number on some of the assemblies. I changed the intially called assembly to be ver 1.0.0.2, from 1.0.0.0. NOw when I start the application I receive the error "Cannot find the assembly ... version=1.0.0.0" Where is it getting this reference to version 1.0.0.0? I've changed all the assemblies to be version 1.0.0.2 but it's giving me this error and I can't proceed. Any help is greatly appreciated. Tag: Fereshing an open form Tag: 99541

Jonathan,
I don't see a problem of doing so. As long as you have a reference to the
form you want to refresh you can call any visible methods.
