    - RichTextBox control I've just started messing around with the new .NET 2.0 RichTextBox control and I've got a question. How would I, for example, underline the selected block of text bearing in mind that the selection might consist of different fonts and / or styles (ie. SelectedFont will be 'null') Tag: Word Document Tag: 87170

    - Add / Remove Program Hello When we build a setup project. As long as we use the same setup.msi, it will give you the option of repair & remove. However, if I send them an update, it tells you have an instance of the program installed, remove it by going to add / remove. Is there a way I can give them a remove option in my updated setup.msi as well ? That would help a lot! Thanks HS Tag: Word Document Tag: 87167

    - Putting custom objects on the clipboard All, It seems that there has been some discussion of this issue, but I can't find any real answers. How does one copy a custom object onto the clipboard and then retrieve it? I can do this with standard types and collections of standard types, but if I use a custom object the retrieved objects are always null. For example, given the following class: public class MyObject : Object { private string m_Name = ""; public MyObject(string name) { m_Name = name; } public string Name { get { return "MyObject:"+m_Name; } } } this code does not successfully copy/retrieve a MyObject object usign the Clipboard: MyObject myObj = new MyObject("Foo"); DataFormats.Format f = DataFormats.GetFormat("MyObject"); DataObject dObj = new DataObject(f.Name, myObj); Clipboard.SetDataObject(dObj, false); // Get it right back out IDataObject obj = Clipboard.GetDataObject(); if (obj.GetDataPresent(f.Name)) { MyObject stuff = (MyObject)obj.GetData(f.Name, true); if(stuff == null) MessageBox.Show("GetData failed for " + f.Name + "!"); else { MessageBox.Show("MyObject on Clipboard was: " + stuff.Name,"GetData successful!"); } } The GetDataPresent call is successful, but a null reference always comes back from GetData; the autoConvert param doesn't seem to have any affect. Do custom objects have to implement some interface or derive from some base clsss to make this possible? Must they be cloneable? Serializable? Any advice or suggestions?

    - MessageBox problem Hello, When I use MessageBox.Show(owner, ...) to display a modal dialog box the 'bong' sound is made immediately but the message box is not painted. For some reason, pressing the ALT key will cause the message box to appear. The application contains around 15 windows forms, spread over all the screen space on three monitors. I know that the message box is not being painted behind one of these forms as I deliberatlely left space on the screen where it would appear and it appeared when I pressed ALT, but not before. So it is not an issue with the Topmost property of the forms. Any ideas? The problem occurs with every message box in the application. I think it is related to the amount of painting going on since if I minimise all the forms in the application except the one that will display the message box it works. However, even when all displayed the forms appear to be repainting correctly so I have no idea how to correct this issue... Cheers, David Tag: Word Document Tag: 87162

    - winform fails to set size correctly! There must be something happening behind the scenes to "help" me, but I've got a real problem. I've embedded an AxWebBrowser directly onto a form, and I'm trying to set the size of the form to accomodate the contents. The width sets to a predefined number of pixels (816) correctly, but I can't get the height to work. The code setting the height is below. You can see what I'm doing is trying to set the form to be so tall that there's no vertical scrollbar. I do that by asking for the size of the scrollHeight, and growing the form so the client area is as large as the value of scrollHeight. But this code fails. The value of desiredHeight comes back with 7409, and the currentHeight is 293, for a delta of 7116 and a targetHeight of 7436. But when I set "this.Height = 7436" the form only grows to to 1036. That number is always the same. My screen resolution is 1280 * 1024. Does that affect the maximum possible size of a winform? Would I get the growth I need if I rendered this offscreen? The real reason I'm trying to work this out anyway is to do a screen capture and turn HTML into TIFFs, so doing it offscreen (or in memory) is the real target here, anyway. private void FitVertical() { MSHTML.HTMLDocumentClass doc = (MSHTML.HTMLDocumentClass)AxWebBrowser.Document; MSHTML.HTMLBodyClass body = (MSHTML.HTMLBodyClass)doc.body; int desiredHeight = body.scrollHeight; int currentHeight = this.ClientSize.Height; int delta = desiredHeight - currentHeight; int targetHeight = this.Height + delta; this.Height = targetHeight; } Tag: Word Document Tag: 87157

    - Has the EnableVisualStyles bug hit me? Hello All, I have a .NET application running on Windows XP. I have quite a few forms, some modal and some modeless. Once in a while we get a wierd exception in the application and most of the time the code is transferred to the top level 'ThreadExceptionEventHandler'. It is difficult to get the information on actual exception. Most of the time it seems to say "External component has thrown an exception' and the source of the exception object is 'System' Doing a bit of searching on the internet, I came across the known bug in EnableVisualStyles( ). I do not call the Application.EnableVisualStyles at all. but I do call Application.DoEvents (this was suggested as a fix somewhere) I tried looking for the comctl32.dll. In the System32 folder the dll has version 5.82. One of the articles on the internet said, XP uses 6.0 by default. Where would this dll be? I do get rounded corners for my form's title bar, does this mean that my application is using visual style? If yes where is it getting set? Is it the default under Windows XP (SP2)? Can somebody direct me to information which will lead to better understanding of visual styles and the related bug. I don't even know whether what I am facing is the same bug or not TIA, --Saurabh Tag: Word Document Tag: 87136

    - Displaying a regular windows app inside a control window What I am trying to do is launch a windows application from within my WinForms application. Once this is done I want to have this external application behave like a control on my WinForms app (no longer appears in status bar, no frame etc.). I remember seeing a Code Project article describing how to do this, but hours of googling for it has not turned up anything. Does anyone reading this remember the article? While I can launch an application using System.Diagnostics, find a windows handle using an API call I wouldn't have a clue how to modify it. Does anyone know how I could go about modifying the application? I would really appreciate any help and I am sure I won't be the only person who would benefit from this knowledge. regards, Rick Tag: Word Document Tag: 87135

    - Double buffer a form Is there some trick to double buffer a whole form without having to subclass every single control on it to make each control double buffered? I've noticed that when I resize my form the controls on it starts flicking so much it's not even funny. I thought I could be clever and do something like this foreach(Control c in this.Controls){ // Set the value of the double-buffering style bits to true. c.SetStyle(ControlStyles.DoubleBuffer, true); } but that won't work since the SetStyle method is declared as protected in Control. (Why is it declared protected?) Martin Tag: Word Document Tag: 87123

    - Maximising window using shortcut I created a windows form (using J#), set the BorderStyle to FixedDialog, and disabled the maximise box. All I wanted was that the user should not be able to change the size of the window. After my application was built, I created a shortcut to it. In the shortcut properties, I set the Run: property to "Maximised" from "Normal Window". When I started the application from the shortcut, it was maximised. I could neither resize the window, nor "restore" it (as expected). I think this behavior needs to be looked into. I feel that if an application's maximise button is disabled, then the shortcut should'nt be able to show the form as maximised. -- Sushovan, a crazy junior Tag: Word Document Tag: 87116

    - GUI issues in MDI application Hi , Please help me with the following issues as soon as possible. Thanks in advance for all of the timely help. I have a MDI windows application made in VC#. It has 3 child forms and each form contains 4 panels each. Besides this I have a login form which is not the MDI children . At run time the application start with a class (which ensures that there is only one instance of application), then control comes to login form and then comes to MDI parent form. I have some doubts and problems with GUI. 1. I am not able to disable the ControlBox of the MDI Children forms. I have set the following properties for all of the MDI child forms... ControlBox=False; MinimizeBox = False; MaximizeBox = False; I searched for the issue and found it as a big bug in DotNet on the following link ... http://www.dotnet247.com/247reference/msgs/33/169116.aspx Unable to remove the control box is messing up my application. 2. I read somewhere that if you don't set the project's starting object(at runtime) as MDI parent form, then MDI applications in DotNet create problems. Is it true ? 3. I have some common panel and functionlity. Right now that common panel has been replicated on each of the form. What is the best way to use these common panel and where to put the functionality. 4. How to change the the background colour of MDI Parent form. Right now I am using the following article but it is not changing the background colour of my form. The link is ... http://support.microsoft.com/kb/319465/EN-US/ 5. A strange issue .. Whenever I minimize the MDI parent form and restore it.back, the panels relocates in down direction. Each time I minimize it and restores back , it keep on moving in the downward direction. I don't have extensive experience of working in C#. Please forgive me if the issues seems to be silly and guide me. Thanking you, Rajat Tandon. A DotNet Learner. Tag: Word Document Tag: 87108

    - Embedding a form into a panel control I am embedding a form into a panel control using pnl.Controls.Add(form); This works pretty well, however there is one problem. The panel can resize, so there are cases when the panel size is smaller than the form embeded in it. The framework handles this problem by showing only a piece of the form that fits in the panel. Is there a way to add scroll bars to the panel so that the user can view the entire embedded form without resizing the panel? Is there any piece of code that handles this whole situation?

    - DataGrid: Update datasource when closing form Hi, The situation is the following: A user is editing a cell in a DataGrid, and hasn't pressed <return> or <enter>, so the value is being edited. The user then closes the form. I would like to update the value to the data source if it is valid, or prevent closing the form if the edited value is invalid. Actually, all I need for this to accomplish are the following two functions: (1) A function that tells me whether or not the user is actually editing a cell's contents. (2) A function that tries to end the edit operation, and returns whether ending the operation succeeded. Ending the edit operation should fail if the value being edited is invalid (not valid). I haven't found these yet. About (1): I've checked DataRowView's IsEdit member, but I tested it and it seems to return true even if a user isn't editing a cell in that row. About (2) DataGrid has an EditEdit method. Sadly it returns false when no cell is being edited, so I can't make the distinction between an invalid entry or the fact that the cell isn't being edited. So using (2) alone doesn't work. Thanks for any help -- Tom Tempelaere. Tag: Word Document Tag: 87076

    - ActiveX controls causing multiple calls to UserControl's OnLoad If I host ActiveX controls on a UserControl, the designer inserts calls to the controls' EndInit methods into the UserControl's InitializeComponent method. Every time EndInit is called (once for each ActiveX control), the containing UserControl's OnLoad method is called. Is this by design? If so, how am I supposed to deal with it? If I host the same controls on a Form, the Form's OnLoad is only called once, even though EndInit is called for each control. I posted about this a few days ago; still puzzling over it. http://groups-beta.google.com/group/microsoft.public.dotnet.framework.windowsforms/messages/3e6859dfbd8a4ecb,e2b3a9fdc23b41ec,73c8eafc4da4abb9?thread_id=8fcf88093bfceaf6&mode=thread&noheader=1&q=OnLoad+UserControl#doc_3e6859dfbd8a4ecb Tag: Word Document Tag: 87069

    - major challenge : strange problem with drag&drop of Outlook2003 msg to vb.net form Hi, I'm desperatly trying to find how I can use drag and drop for an Outlook 2003 msg towards a VB.Net Windows application. Normally you should use Dim theSteam As Stream = CType(e.Data.GetData("FileGroupDescriptor", True), Stream) to capture the filename (which works great) and use Dim ms As MemoryStream = CType(e.Data.GetData("FileContents", True), MemoryStream) which returns nothing. The strange thing is that e.Data.GetDataPresent("FileContents") returns true. I also tried to copy an msg file to the clipboard and tried to download the message from the clipboard into my vb.net application but same behaviour. I also tested the same thing in c# but no changes. Can someone please advice what's wrong ? Is this a bug gentlemen from Microsoft ??? Thx for some feedback !!! Tag: Word Document Tag: 87068

    - NUnit, NMock and DataBinding Hi all, Can anyone share their experiences (at a high level) mocking a database that fills a Dataset that is bound to controls in a UI? I'm finding the task rather daunting. Cheers, WNC Tag: Word Document Tag: 87063

    - databinding issue Hi, I've got the following problem with databinding: If I bind a column of a dataset e.g. on the Text property of a Textbox, everything acts as expected, i.e. if you don't make any changes to the text in the textbox, the rowstate of the bound row stays unchanged. On the contrary, when you bind e.g. the Tag property of the Textbox, instead of the text property, the rowstate turns to modified when leaving the textbox (or by calling the bindingmanager.endcurrentedit method), even if you haven't changed a thing. This is very inconveniant because it causes unnecessary updates of the database. It seems that binding on the non default property (which is Text) causes changes of the underlying dataset. I assume it has somtehing to do with adding attributes to the properties ? or not ? How can we avoid this ??? Thanks !!! Tag: Word Document Tag: 87062

    - How to close a form in C# I'm trying to close a form in C#. I have a vb background, so the question may sound dumb. In vb it is just me.close(). I've tried a bunch of ways to close the form but C# is acting pretty dumb also. I can't find a way to close it. Here are some of the things I've tried: private void button1_Click(object sender, System.EventArgs e) { // Form1 frmI = new Form1(); // DialogResult dr = frmI.ShowDialog(); Form1.Quit(); // this.Hide(); } The new form seems to recreate the form - that is a total nightmare. Hide doesn't end the program and Close just gets a message that says close is not defined. -- Regards, Jamie Tag: Word Document Tag: 87049

    - Several bugs and workarounds In the course of writing my application, I have come across several = issues that seem to be Microsoft bugs. Following is a summary and possible workarounds. Jeffrey Tan, if you are reading this, please verify. Also, I'd like to know how to request fixes for these issues. 1) Sometimes the designer decides to spontaneously rearrange the tabs in = a TabControl. Status: Verified "known issue" - "Tab control TabPage order is = randomized" Workaround #1, suggested by Herfried K. Wagner Make sure you have always the first tab selected when recompiling Workaround #2: Delete and recreate the tabs after the call to = InitializeComponent() // Sample pages =3D new TabPage[] { pageOne, pageTwo, pageThree, pageFour, = pageFive }; myTabControl.Controls.Clear(); myTabControl.Controls.AddRange(pages); 2) BeginUpdate/EndUpdate does not work correctly when adding a single = item to a sorted ListBox Status: Verified "known issue" Workaround #1: Check the number of items to update and only perform = BeginUpdate/EndUpdate if >1. if (items.Count > 1) myList.BeginUpdate(); myList.Items.AddRange(items); if (items.Count > 1) myList.EndUpdate(); Workaround #2: Toggle the Sorted property. // Sample myList.BeginUpdate(); bool bug_workaround =3D myList.Sorted; myList.Sorted =3D false; myList.Items.AddRange(items); myList.Sorted =3D bug_workaround; myList.EndUpdate(); 3) A DataGrid leaves text on the screen after deleting a row containing = a selected (highlighted) cell. Happens when the columns are set to read-only, mostly visible when = deleting the last row. Status: Verified "known issue" Workaround: Set the read-only property of the whole DataGrid to true and = the read-only properties of the individual DataGridTextBoxColumn items to false. Don't know about cases when only some columns need to be read-only. 4) A DataGrid on a TabPage loses the data binding if the is deleted from = the TabControl. Since the only way to hide tab pages is to remove them, it is relevant. Status: Happens on my machine... Workaround: un-bind and re-bind the DataGrid when removing & re-adding = the tab page. Those are the bugs that I encountered. If you know of more, please post. --=20 Address email to user "response" at domain "alexoren" with suffix "com" Tag: Word Document Tag: 87044

    - Creating a scrollable container control I would like to create a custom container control which can scroll its child controls. I know that the AutoScroll property of ScrollableControl can mimic this functionality, but AutoScroll causes some behavior which is EXTREMELY obnoxious to my users, and I haven't been able to find a workaround. Consequently, I would like to be able to scroll a control without using the AutoScroll property. Is there any way to accomplish this? I've created the appropriate scrollbars, and now I just need to get the child controls to move. The SetDisplayRectLocation() function sounded like exactly what I needed, but it doesn't seem to work unless AutoScroll is enabled. Tag: Word Document Tag: 87033

    - Windows Form in Shared Add-in not reading App.config settings Good Morning, I am developing an Outlook Shared Add-in using VB.Net. A Windows form has been added to the project, but is not reading the values in the app.config file during testing. The code (Sub Main) is below and displays "Blank connection string" is the label. It is called by an Outlook command button click event: Private Sub btnCTXNotesHistory_Click(ByVal Ctrl As Microsoft.Office.Core.CommandBarButton, ByRef CancelDefault As Boolean) Handles btnCTXNotesHistory.Click Dim frmNotesHistory As New frmCTXNotesHistory frmNotesHistory.Main() frmNotesHistory.Show() End Sub Sub Main() Dim sqlconCTXControl As New SqlClient.SqlConnection sqlconCTXControl.ConnectionString = ConfigurationSettings.AppSettings("sqlconCTXControl.ConnectionString") lblErrorMsg.Text = sqlconCTXControl.ConnectionString.ToString If lblErrorMsg.Text.Length = 0 Then lblErrorMsg.Text = "Blank connection string" End If End Sub Thanks.

    - InvalidCastException: (DataSet) DataGrid.DataSource I need some help please. Say you have a DataGrid and a DataSet, and you create a dataview to handle sorting and filtering and then you assign the dataview to DataGrid.DataSource. Once you did that you will get InvalidCastException if you do this: DataSet dataSet = (DataSet) dataGrid.DataSource; But I need to do that because I need to get the DataGrid's dataentries in a dataset and use XmlDataDocument to load the dataset and then write it to an xml file. Maybe my first design decision to assign dataview to the datasource should be reviewed. I don't know. Any comment will really help. Thank you. Tag: Word Document Tag: 87030

Hello,

I am using the following code to open a word docuement:

With WrdApp
.Documents.Open("C:\My Documents\MyDoc.doc", missing, missing, missing,
missing, missing, missing, missing, missing, missing, missing, missing)
.Selection.Paste()
.Visible = True
.Activate()
.NormalTemplate.Saved = True
End With

1) I have noticed that this does work with Word 2002, but it does with all
other versions. Any Ideas?

2) When the user goes to save the document it defaults to MyDoc.doc, is
there a way to change the name (programmatically) that will default to a
different name instead of MyDoc.doc.

Thanks,

Chuck

Ask in a Word newsgroup. It's nothing to do with .NET, surely.
