    - addhandler and removehandler - work as advertised? I have code in a form load (and I tried it in New() too) that says: "Removehandler me.comboCity.SelectedIndexChanged, me.comboCity_selectedIndexChanged" I needed to disable processing of the combo being changed while the control binds to the arraylist data via standard data binding during form load. Then after the data loads and the form is done I code: "AddHandler me.comboCity.SelectedIndexChanged, AddressOf me.comboCity_selectedIndexChanged" But the event still fires while the databinding is taking place, why? The event was supposed to be disabled? Thanks, Jeff Tag: help - can not modified crystal report when switching computers Tag: 53479

    - Unrepeatable form bugs -- Is 100% managed .Net Stable? I am getting the following UNREPEATBLE symptoms on my 100% managed application:- - Form will not close via window close button. Need to Application.Exit(). - Keyboard events lost, cannot access the menus with Alt- - Null pointer exceptions deep within the Windows runtime. - TextBox OnValidated events stop firing after a while. OnLeave still works. Something is destabalizing the entire system. Feels like the bad old days of C++, eg. a corruped pointer. But that should not happen in .Net. Has anyone had similar problems? The application is very simple, with only one main form, only one thread. One complication is that it uses a Model-View-Controller approach and if the model changes too much I just recreate the guts of the form from scratch. The form has a TabControl which is permanent. But I periodically TabControl.Clear() and then recreate all the tab pages. I have not bothered removing the individual controls on the page before the .Clear(), I would expect this to recurse automatically. I have created a small dummy TextBox on the main form, and I send the focus their before doing a Clear. This seems to reduce the crashes. But one problem -- the textbox sometimes refuses to accept focus for no apparent reason. This is worrying. One can waste a lot of time hacking around buggy systems changing things in the hope that the bugs will disapear. Not having the .Net sources is also a worry -- I don't want to have to read them but in the event of a crash they are handy. Maybe we should have used Java.

    - What is the proper way to cancel the closing of a MDI application? Hi, I have an MDI application. If the user presses the close button (the X in the upper right), I need to check each child form and see if it is dirty and give the user an opportunity a) lose their changes, b) save changes and continue closing, or c) abort the close action. I have code that presents these choices and does the correct thing from the MDI child's point of view, but I am search for a mechanism for notifying the MDI parent that a child has aborted the close. So far my code looks like: Private Sub myApp_Closing(byVal sender as object, byVal e as System.ComponentModule.CancelEventArgs) Handles MyBase.Closing Dim frm as form for each frm in me.MdiChildren frm.close() next End sub I suppose I could add some global that I check each time in the loop, but I thought that Windows.Net had a better mechanism. Any thoughts? Thanks, Jerry Tag: help - can not modified crystal report when switching computers Tag: 53462

    - Patial Undo Disaster Using VS 2003, VB.NET.. There is a disastrous bug in the "undo" icon that cost me a lot of work... I had a data grid with an intricate collection of GridColumnStyles (i.e. created via properties, DataGridTableStyles Collection). I accidentally deleted the DataGrid in the WinForm, and immediately pressed the Undo icon which restored it and the DataGridTableStyles. To my horror, I realized later, it did not restore the GridColumnStyles collection at all - it was completely lost. If undo does not completely undo an action, it should warn you. Very frustrating... How do we know when undo completely works and when it only partially works? Bob Day Tag: help - can not modified crystal report when switching computers Tag: 53461

    - DataGrid questions using VS 2003, Vb.net... In a WinForm, I have a datagrid with a parent child relationship named "Display Details". When you click on the + next to the Parent row, below it you get "Display Details" - when you click on that, you get the related child rows of the Parent row. Everything displays correctly. The parent row represents a telephone line (1,2,3 etc) and the child row represents what is happening real time on that line (Parent Line 1, Child Row 1 - Playing Greeting, etc.). So rows are constantly being added to the child rows (i.e. the dataset) (whether displayed or not). Question 1 - The "Display Details" seems non-standard windows programming. When you click a + next to an item, you expect to expand what ever is under it. Is there any way to get rid of the "Display Details" and just automatically expand to the child rows? There is only this one relation in the collection. Question 2 - I would expect "if mygrid.isexpanded(0) = true" to tell me that the datagrid for row 0 is expanded and the child rows are displayed. It does not. It only tells me that "Display Details" is visible or not. Toggling mygrid.expanded and mygrid.collapsed. simply displays or doesn't display the "Display Details" option. This is pretty useless. How can I determine if a Parent row is displaying the child rows or not? Question 3 - With a Parent row expanded to display child rows, how do I modify the Parent row? You would think that simply modifying the corresponding DataSet column value would accomplish this, but this generates an error that I cannot make sense out of. How do you update a Parent Row while it is expanded shows related child rows? Question 4 - Updating a Parent row column value(not a column used in creating the parent/child relationship) seems to always collapse the child rows for that parent row. Is there a way around this? Question 5 - Adding child rows to the DataSet does not display them in the datagrid if the screen is already full with previously child rows. You can, of course, scroll down to see it. How would you make the last child row added visible? Thanks for your help. Bob Tag: help - can not modified crystal report when switching computers Tag: 53460

    - Sending a custom Windows message Hi, can anybody tell me if there is a way to define and send a custom windows message to a window and to specify a handler function for it in C#? The reason I'm asking this is following - I use some 3d party component that start its own threads. When my command is executed by this component it invokes my callback in the context of its thread. But I need to somehow update my GUI after that. I can't access my GUI controls from this callback (get an exception - wrong thread or something like that), so I thought that if I could place a message into my app's message queue then I could handle this situation properly.

    - 2nd Repost: Problem Retrieving DataSet Returned By A WebService... anyone from Microsoft or anyone with solution? Hi, I'm working on a project which includes WebServices and Windows Form application. The Windows Form application will call the WebServices to retrieve data from database. The data will be returned as DataSet. Now, here's the problem. On .NET Framework 1.1, if any rows in the dataset returned contain errors (marked by calling the SetColumnError() method or setting the RowError property of the DataRow), I get the following error message in the Windows Form application, "There is an error in XML doument (1,xxxxxxx)" If I forced the Windows Form application to run on .NET Framework 1.0, everything works fine. Is this a bug? Or I need to make some code adjustment because of changes to the Framework? Here's the partial code for the WebService project Code: <WebMethod()> _ Public Function RetrieveDataSet() As DataSet Dim ds As New DataSet Dim dt As New DataTable Dim row As DataRow Dim i As Integer dt.TableName = "TestTable" dt.Columns.Add("TestColumn1", GetType(String)) dt.Columns.Add("TestColumn2", GetType(Integer)) ds.DataSetName = "TestDataSet" ds.Tables.Add(dt) For i = 0 To 10 row = dt.NewRow row("TestColumn1") = "This is row " & i row("TestColumn2") = i dt.Rows.Add(row) ' The following code trigger the error after the DataSet ' is returned to the calling Window Form application row.SetColumnError("TestColumn1", "Error message here") Next Return ds End Function For the Windows Form application, you need to insert a datagrid control (assumed as datagrid1). It will look something like this, Code: Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim ws As localhost.Service1 Dim ds As DataSet Try ws = New localhost.Service1 ds = ws.RetrieveDataSet Me.DataGrid1.SetDataBinding(ds.Tables(0), "") Catch ex As Exception MsgBox(ex.Message) Finally If (Not (ws Is Nothing)) Then ws.Dispose() End If End Try End Sub I really hope someone could help me out with this one. Thanks in advance. ps: Please, before anyone reply to state that I did not choose the appropriate groups when making this post a crossposts post, please know that I'm currently in blind on what is causing this error. Is it the WebService? or is it the ADO .Net? or is it Windows Form application? or is it VB .Net? Well, it has something to do with WebService as it only happens to the DataSet returned by WebService. It also has something to do with ADO .Net as I'm using DataSet. And it definitely has something to do with Windows Form application as if I force the Windows Form application project to run on .Net Framework 1.0, everything works fine.

    - Delete Datgrid's Last Row, Click on the grid again, Get the Exception. Hi All, I am using a custom collection (inherits collection base) and set it as the datasource of the Datagrid. Everything works great except when I delete the last row. WHEN I CLICK ON LAST ROW ON THE GRID IT GIVES THE FOLLOWING ERROR : "An UNHANDLED exception has occured in your application.If U click Continue ,the application will ignore the error and attempt to continue. If u click quit , the application will be shut down immediately. Index was outside the bounds of the array!." The title of the messagebox is 'error when committing the row to the original datastore'. Im wondering how its going to commit the row to the original datastore when its a custom collection of software objects??? THE BUG happens EXCATLY when I delete the LAST ROW in the grid then try to click anywhere in the grid!. private void btnDeleteReference_Click(object sender, System.EventArgs e) { if(referenceCollection.Count>0) { if(dgReferences.CurrentRowIndex >=0) { referenceCollection.RemoveReferenceAt(dgReferences.CurrentRowIndex,App.Connection ); //dgReferences.CurrentRowIndex=0; dgReferences.DataSource = null; dgReferences.DataSource = referenceCollection; dgReferences.Refresh(); //int i= referenceCollection.Count-1; try { this.dgReferences.CurrentRowIndex = 0; } catch(Exception exxx){} //dgReferences.CurrentRowIndex = referenceCollection.Count-1; } } } I've tried with several combinations of assigning a valid integer to CurrentRowIndex ptoprty of the grid (Commented lines) to avoid the error. Still it throws the exception telling Invalid index, index should be non-negative or less than the bounds of the collection. I tried to catch the exception while assiging an integer to the currentRowIndx property, then too, exception is thrown by the Application's Main form, parent of my Form. What is this??? I found somewhere on the NET that this is a bug in MS Datagrid. But the worst thing is that even the SelectedIndex property is failing to work. I AM REALLLY FRUSTRATED!! Please help me out! :-( Thanks in advance, Sheetal Tag: help - can not modified crystal report when switching computers Tag: 53405

    - Transfer an event to a different control Hi A simple question: I have a form with a ListBox and a RichTextBox. The user selects the list box and types some characters. I am trapping KeyPress events on the list box, and want to simulate having the rich text box receive that key press, so that the characters would also appear in the text box. I don't want to alter the text of the text box programatically with SelectedText=, because the text box is also taking care of the effect of backspace and other key presses. I believe that if one control contains another, the event is passed up the container hierarchy until it is handled, so I could set Enabled=false. But how can I transfer the event between peer controls, and can this be done in managed code?

    - WebBrowser ctrl: switch off context menu in C#? Hi, I am using the AxSHDocVw.AxWebBrowser web browser control in my windows forms application in C# and I would like to switch off the context menu of the browser. Currently, I only found a solution for c/c++: It seems that one has to implement the IDocHostUIHandler interface, which should be defined in the mshtml assembly. Apparently, it is not there. Any ideas? Other solutions welcome as well! Thanks in advance, Guenter Tag: help - can not modified crystal report when switching computers Tag: 53345

    - Long drawing loop cancellation Thinking about a standard "silly" problem of giving a user an option to cancel long drawing loop, I read a lot of articles and did some investigations of my own. (I work with C# .Net 2003). My application must provide a very sophisticated drawing, which is actually a millions-length sequence of simple line or ellipse drawings executed in a very long loop. Naturally, I'd like to give a user an option to cancel the drawing. I have a number of rather bad solutions and I don't see any acceptable one. The Solutions are: 1. The drawing loop is execute in the UI thread and calls DoEvents() to allow "Cancel" button to be pressed. The downside is well known (see DoEvents() method adoption discussions) ? UI thread is busy and natural events sequence is broken. 2. The drawing loop is executed not in the UI thread. The downside is seldom exceptions. Generally, as I know, .Net does not allow drawing from non UI thread. 3. The drawing loop is executed not in the UI thread but all drawing operations are executed in the UI thread by calling Invoke for each elementary drawing operation. Theoretically, this must be the correct schema! . The downside is that Invoke() is a very expensive call, so it works inappropriately long (see table below). 4. Using memory-stream metafile for buffering. Actually, this is not what I need; in addition, it works even longer then #3. Here is the execution time comparative graph for different implementations of a loop with 2,000,000 drawing lines on my PC. 1. Execution in the UI thread (without DoEvents() calling) - time 00:00:04.6250592 (given as 1) and no "Cancel" available 2. Execution in the UI thread (calling DoEvents() on each step) - 00:00:10.5937500 (2.3 times longer) 3. Execution in a non UI thread (calling Invoke() for each drawing operation) - 00:05:41.560314 (73.8 times longer) 4. Drawing in memory-metafile (no DoEvents() or Invoke() ) - execution time 00:05:06.7153993 (66.3 times longer) Of course, 5 minutes instead of 5 seconds is too much for such a common task (a long loop cancellation). Any suggestions will be deeply appreciated. Alex Tag: help - can not modified crystal report when switching computers Tag: 53342

    - Cannot find CrystalReportViewer control I did a full installation on VB .NET version 7.0 and .NET framework 1.0. I tried to find the CrystalReportViewer in the Toolbox but I couldn't. I also tried to look for it in Tools/customize toolbox but still weren't successful. Is it something to do with the VB .NET standard version or enterprise version? Also I found some control called CrystalReport, but it is not mentioned in the .NET document. What's the difference between this one and CrystalReportViewer? Thanks in advance.

Hi,

I hope I am posting the questions on the correct news group.

I created a report using Crystal Report.NET (VS.NET 2003 edition on Windows
XP Pro) in my notebook. I then modified the report on my desktop (VS.NET
2003 edition on Windows 2003 Std Server). After which I could no longer
modified the report on any other computers except on my desktop. I had tried
to modified it on my notebook and another notebook (VS.NET 2003 - Windows
2000 Pro).

What happen? Did I somehow lock the report?

Thanks

John Yung
