    - FileSaveDialog and default file extension This is a multi-part message in MIME format. ------=_NextPart_000_0071_01C4C67A.66A29FA0 Content-Type: text/plain; charset="Utf-8" Content-Transfer-Encoding: quoted-printable Hi, I am using System.Windows.Forms.SaveFileDialog to prompt the user to = select a file to which data is exported. I would like the control to always add the default extension, in this = case .xls, to whatever filename the user enters - but the default = behavior is that the extension is only added if the user has not already = entered an extension. E.g. if the user types in the filename "export.txt" then the = SaveFileDialog should append .xls to form "export.txt.xls". Of course I could just do this manually after the user has OK'd but then = the dialog's prompt for create and overwrite won't be correct. How can I configure SaveFileDialog to ALWAYS append .xls? Below is a code snippet that I use to prompt the user for a filename: public static string GetExportFilename() { System.Windows.Forms.SaveFileDialog saveFileDialog =3D new = SaveFileDialog(); saveFileDialog.DefaultExt =3D = "*.xls"; saveFileDialog.Filter =3D "Excel = 8.0+ (*.xls)|*.xls"; saveFileDialog.AddExtension =3D = true; saveFileDialog.CheckPathExists =3D = true; saveFileDialog.CheckFileExists =3D = false; saveFileDialog.CreatePrompt =3D = true; saveFileDialog.OverwritePrompt =3D = true; =20 string exportFilename =3D ""; if (saveFileDialog.ShowDialog() = =3D=3D DialogResult.OK) { exportFilename =3D = saveFileDialog.FileName; = =20 =20 } =20 return exportFilename;

    - Renaming/Replication of win forms Hi, Can anyone give me an idea of the best way to copy/replicate a win form? Whenever I simply copy, I get problems with the class no longer being recognized as a form. Also, when renaming a form, is there any way to ensure that all the relevant paths/references within the file are also changed? (e.g. I rename a form, and I want the underlying class name to reflect that change) Thanks in advance for any help... -Yarin Tag: Error: Microsoft JET Database Engine Tag: 80193

    - ScrollableControl bug? OK, this is a very odd but simple to reproduce bug that happens when anchoring controls inside a panel or any inherited class from ScrollableControl. Symptoms The designer will adjust the width of a control to a different width than set when it's placed on a scrollable control where the vertical scrollbar is visible from within the designer and it's anchored on the right. How to reproduce 1 - Place a panel on a form. 2 - Set the panel's AutoScroll property to 'true' 3 - Put 2 buttons inside the panel 4 - Move button 1 to overlap the bottom of the control to force the vertical scrollbar to appear. 5 - Anchor button 2 to the right of the panel 6 - Save and close the form. 7 - Open the form in the designer and notice the width of the anchored button has been adjusted. 8 - Adjust the size of the FORM not the panel. Repeat step 6 + 7 noticing that the buttons width reduces furthur for each close and open of the form when changes are made and saved. Tag: Error: Microsoft JET Database Engine Tag: 80190

    - Prevent a combo box SelectedIndexChanged event firing multiple tim I am working on a form where the user select a value from a combo box and depending on his selection a popup window display, asking for more information. My problem is that this popup is displayed twice when the user makes the selection. Another problem is that this combo box is on a multi tab page and when the user selects the tab for the first time the combo is on, the popup is also displayed twice. How can I get the event to only fire once and only when the user selects an item in the combo box? Thanks in advance for your help, Johannes Tag: Error: Microsoft JET Database Engine Tag: 80171

    - WinForms application not appearing in taskbar until focused Hi All, I have a WinForms application (running under Framework 1.1) that loads correctly, but if it isn't focused at load time, a corresponding button doesn't appear in the taskbar. When the application is given focus by clicking on it, or switching to it via Alt-Tab, a button for the application appears in the taskbar. This happens even with the ShowInTaskbar property of the form set to true in code. Has anyone come across this problem? I've searched Google and MSDN but found nothing, yet this smells suspiciously like a Framework bug to me. Yours, Duncan Bayne Tag: Error: Microsoft JET Database Engine Tag: 80159

    - Keyboard shortcuts Hi All, I have a form that contains many controls, including a custom control. That custom control contains a number of child controls, including a button with the text "&Search". When the custom control or one of its child controls has focus, pressing Alt-S causes the button to be clicked. When one of the other controls on the form has focus, pressing Alt-S does not cause the "&Search" button to be clicked. Is this a WinForms issue, or am I misunderstanding something?

    - Printing Text With a Watermark I have a production application that prints textual information, plus a graphic watermark on each page. Currently it uses a PrintPageEventHandler from the System.Drawing.Printing namespace to add the watermark and text to each page. The watermark is the same on each page, and is derived from a WMF file whose size is about 120 KB. The problem is that the spool files that are produced when we print are somewhat large. The spool files without the watermark are only about 10 KB per page. With the watermark (derived from a WMF file) the spool files are about 300 KB per page. What I would like to do is send the watermark only once per print job. This would greatly decrease the load on the network and print server. How can I accomplish this?

    - The transport failed to connect to the server I'm using VB.NET 2003 to writing a Windows application and I want it to send email. I've been assuming the easiest method is by using System.Web.Mail.SmtpMail. I point a specific server using: System.Web.Mail.SmtpMail.SmtpServer = "BANANA". That server is our Exchange Server. Everything works great for ME on my computer. However, when I give the .EXE to someone else to run they're getting an error: "System.Web.HttpException: Could not access 'CDO.Message' object. ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Runtime.InteropServices.COMException (0x80040213): The transport failed to connect to the server." My devbox has the SMTP service installed. The other guy's computer does not. Is that why its failing on his computer? I'd hoped that if I point to a specific server for delivery (rather than default to localhost) the SMTP service wouldn't need to be installed on the host running my program.

    - listbox shows blank items Hi, I have Windows 2000 SP4, Visual Studio 2003 (Microsoft Development Environment 2003 / Version 7.1.3088), with Microsoft >NET Framework 1.1 (Version 1.1.4322 SP1). Using C#, C++, or VB I create an application with one form containing only a listbox, a textbox and a button. The only code I type is for the button: when clicked the code copies the text from the textbox to the listbox: in C#: private void button1_Click(object sender, System.EventArgs e) { listBox1.Items.Add(textBox1.Text); } It appears the text is copied (I can select it), but no text appear in the listbox. When run the compiled program on a colleague's Windows XP computer the result was the same! Is this a framework issue (I hardly believe that!)? Something on our computer's setup? Any suggestion appreciated. Many thanks Tag: Error: Microsoft JET Database Engine Tag: 80145

    - ErrorProvider question I'm binding an ErrorProvider object to a dataset by calling ErrorProvider.BindToDataAndErrors() in a WinForms app. That seems to be working fine. The only issue I've found is that the error string displayed by an ErrorProvider has the name of the column prepended to it. That could confuse users. The list of error strings for a given DataRow does not have the name prepended. So it looks like a "feature" of the ErrorProvider class. Deriving from the class won't solve the problem since the GetError method is not virtual. Has anyone seen this too? Do you know of a way to prevent it? Thanks for any help.

    - DataGrid with DateTime Hi, I have encountered the problem: 1. I have a sql server with a table in it. 2. One of the column's type in the table is datatime. 2. I have a form taht contains a datagrid control. 3. I attached the datagrid to the table in the DB. One of the cells in the table contains the following data (datetime): 11/8/2004 4:14:37 PM (I can see that if I open the DB through the server explorer in visual studio). When I run my application, and the DB is attached to the grid, the cell contains: 11/8/2004 (thats what I see in the grid when I run the application- the time is missing). Is there something I forgot to do? Do I have to configure something? Help will be appreciated, Regards, Ram. Tag: Error: Microsoft JET Database Engine Tag: 80141

    - windows form size at display time Hi, I am a new user to VB.NET. In the past I never had trouble with creating a windows form adding objects and then having it display the same size at run time. I have a form that is exactly the size I want it to be at run time however it is about 20% shorter and 10% narrower at run time , which causes controls not to show up, and some of them are stacking a little bit over each other. How do I make my form appear exactly at run time as it is in design? P.S: I think it might have something to do with the new feature of docking objects to other controls(i.e. : panels) but I have'nt actively done this knowingly on my part. thanks Chris Tag: Error: Microsoft JET Database Engine Tag: 80140

Currently if I do this: Dim msg As New MailMessage With msg .To = "name@domain.com" .From = "My App" .Subject = "My Subject" .Body = "My Body" .BodyFormat = MailFormat.Text End With SmtpMail.SmtpServer = "MachineName" SmtpMail.Send(msg) ....I get a Could not access 'CDO.Message' object. error.

    - hWnd question... I am not sure that I understand what the Control.Handle value represents. The MSDN documentation say that it is "the window handle that the control is bound to." Does this mean that the handle is for the control itself or for the control's parent form? I am trying to call a Win32 API metohd that will set the scroll position of UserControl. The method requires an hWnd, and I am wondering if the control's base.Handle would give me that value. Any insight would be appreciated. Thanks! Tag: Error: Microsoft JET Database Engine Tag: 80070

    - DataGrid ReadOnly Column BUG ! I´ve found a weird behaviour in the DataGrid: Scenario: ---------- I use a TableStyle with several standard TextBoxColumns within. One of that columns have the ReadOnly property set to true. In execution, select the text or a part of it in a cell inside the ReadOnly column. Then, do something that force the DataGrid to loose the focus and afterwards something else that changes its contents (DataSource changed, parent datagrid´s selected row changed, whatever...) After that, the text of the cell you selected is not refreshed, so it still appears in the DataGrid, even if all the rows of the DataGrid disappeared, the text is still there, by itself, looking at me and laughing. The text is refreshed if you give focus to the DataGrid again (by clicking on it or by manually calling .Focus() ). Im afraid I´m not using the correct terms to to search in the groups couse I couldn´t find much about the issue. I think it´s important enough to fix this, you guys out there ;) Thanks in advance.

    - searching in a listbox explorer style Hi If you have multiple items in a listbox, click into the listbox, then type for instante the letter "p", the first item whose text property starts with "p" will be selected. Pressing "p" again will jump to the next item starting with "p", etc. In Windows explorer, you can type multiple letters after each other, and if you're fast enough, they'll be taken as a search term together. For instance pressing "p" then "e" then "a" would lead to the first folder/file whose name starts with "pea" being selected. Is there any way to achieve this functionality in a Listbox as well?

    - OpenFileDialog and DataSet WriteXML strange problem Hi, I have a very strange problem which i hope someone can help shed light on. I have a Windows Forms application which provides data-entry UI. Data inputted is then stored into a DataSet which will be persisted into a XML file using the WriteXML method. The Dataset which contains a Filename data column (type = string); A user selects a file using the OpenFileDialog component. The file name is displayed in a textbox until the user clicks on the Save button. PROBLEM: If the file is selected using the OpenFileDialog.ShowDialog() method, the file name is added to the dataset, but it is not written to the XML file. However, if the filename is manually typed into the textbox, saving to XML file succeeds. Further tests shows that this problem only shows up in WinXP system. Machines running 2000 saves the XML file just fine. In the event of failure, no exceptions nor errors are shown. This is a very strange problem, any help will be very much appreciated!

    - Refresh current form to reflect culture change Hi everybody, I want to add localization support into my windows forms application. Basically, I create a menu item where users can choose a language of their choice. When users choose their preferred language, I want to update all the texts/labels on the current form UI to the new culture, instantaneously. For this, I have created a .resx file for each supported culture and in the event handlers for menu item's Click event, I change the CurrentUICulture property to the corresponding culture as follow: System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("en-US"); However, when the program runs, nothing happens. So, I guess I must somehow force the form to reload itself. I've tried all the methods like Form.Update(), Form.Refresh(), Form.Invalidate(), ... but unsuccessful so far. Does anybody know the solution to this scenario ? Thanks a lot SuperKinhLuan Tag: Error: Microsoft JET Database Engine Tag: 80028

Your question doesn't seem to be related to Windows Forms programming.
microsoft.public.dotnet.framework.adonet would be a more appropriate place.
