.net - Unwanted Wait Cursor In WinForms App
Jul 14, 2009
I have an MDI WinForms app in which the MDI parent form has a ToolStrip, MenuStrip and StatusStrip. Whenever the mouse is moved over one of these controls the cursor changes to a 'wait' cursor (a arrow with an hourglass). This seems to be default behaviour in that there is no code to make this happen. The UseWaitCursor property of both the ToolStrip and MenuStrip is false; StatusStrip does not have this property. This occurs in both debug and release builds and confuses the users who think that the app is 'doing' something when really it isn't! Does anyone know what is causing this to happen, and more importantly how to make it stop?

How can I set the curosr to 'cursor.wait' for the whole display screen and not just for the application form? I have tried "Windows.Forms.Cursor.Current = Cursors.WaitCursor" And several variations but without success.

This VS010 solution is not providing my intended outcome as a custom override of a 'crosshair' or 'reticle' cursor e.Graphics.DrawPath() is the function that isn't working. This
WORKING solution demonstrates how it's supposed to work. The additonal PictureBox added to a Panel is, for reasons I don't understand, not allowing the 'new' cursor to appear.

I'm developing a big VB.Net Winforms application. Every now and again, processing or db connections take some time and therefore I'd like a wait cursor (hourglass) to appear sometimes. I know I can do it like in this thread (in case someone needs the code):Hourglass?- technical discussion - developer Fusion - ASP.NET, C# Programming, VB.NET, .NET Framework, Java and Visual Basic Tutorials However, I have LOTS of code and I don't know when the user will need to wait. So, what I'd really want is to tell my ApplicationEvents file or the like to globally intercept after say 0.3 seconds and turn the arrow (default cursor) into the hourglass and at the same time disable mouse clicks and the like.

I'm coding an advanced web browser. The bad thing is, is that whenever you move your cursor over the window, a wait cursor is displayed. I tried to deselect the wait cursor but it doesn't work! I'm using Visual Basic 2010 Beta 2...

I have a DataGridView control in my Windows Forms Application. I am adding rows to the grid using a background thread. I change the form's cursor to Waitcursor when the process starts and back to Default when it ends. This works well for the form, but not for the grid. When the form's cursor is changed back to default, the grid's cursor does not change, although the cursor over the rest of the form does.
I am updating the grid from a background thread? (The cursor is being changed from the UI thread directly). The background process raises an event, the handler checks the InvokeRequired property of the grid and decides if it needs to "Invoke" the method again from the main thread. So, in effect the actual UI update happens from the appropriate thread. I am not sure if this means that I am "using a background thread" or not.

When I use the Publish command in the Build menu pillar nothing happens expcept for a few seconds showing the wait cursor. This was working a week or two back but I have now installed sp1 for Visual Studio 2010 - is this a bug or is there some way. I can get this working again. I cannot access the project properties either, which is a known problem with SP1, so how to edit the project.vbproj file.

While navigating to a series of sites at one site the WebBrowser control's DocumentCompleted EVENT is tripped and no other recorded Browser events occur after that. When this happens the hour glass cursor indicates the browser is waiting. From this point it take 120 to 250 seconds of wall clock time before the browser resumes. I am looking for a way to force an abnormal termination without destroying the control. I have tried "Stop", "nav to about:blank" repeatedly without success. How can I force an abnormal termination when the Cntrl is in a wait state?
Consider the following: The last known Browser event to be tripped is a Document Complete event; nothing else occurs after this. When this transpires the Cntrl is waiting.

I have a user control, and want to be able to update its cursor while it is disabled. For example, say that I have a user control whose cursor is Default. The below code works ONLY when the user control is already enabled; if it is disabled the below code doesn't work and the cursor remains Default: Me.MY_USER_CONTROL.Cursor = System.Windows.Forms.Cursors.WaitCursor

I have a custom cursor that I have as a ico file as cur files are only mono coloured and 32x32.
The only problem in using a ico file is that I can't set where the hot spot is and at the moment it is set in the middle of the icon which is no help
I was looking on the msdn website and it said to set the hotspot like this
Dim instance As Cursor
Dim value As Point
value = instance.HotSpot But I don't know how to set the point value to (0,54) which is where I want the hotspot to be located.

I am trying to show the square root of the number entered in the textbox. when the user presses Q (Uppercase), the square Root should be shown (in the textbox). I did manage to get the sqaure root, but the problem is that when I press Q the Letter Q is also typed in. For example, if I enter 25 in the textbox and press Q then I get Q5 as the result. Is there any work around to this problem ? Below is the code that I have used.
Private Sub Textbox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress
If e.KeyChar = Chr(81) Then '81 for Letter Q
Dim root As Double = Math.Sqrt(Val(TextBox1.Text))

If I use a button, I can't get rid of the white border apearing around it as soon as I press it. It stays there even after until I press something else. In the button properties I declared the Flatstyle as Standard because I like that look the most.

This is one of those "seems obvious" as how to do, but came across interesting side effect in implementing. I'm trying to keep two text boxes syncronized when information is updated. In this example, I will be using txtStartDate and txtEndDate. If the txtStartDate is changed, then the txtEndDate should should be updated. Likewise, if the txtEndDate changes, I want the txtSartDate to be updated. The side effect I'm comming across is that when I set them up under the TextChanged event for both, the events seem to retrigger against each other indefinately (endless loop?). Am I using the wrong event? Is this a task for a delegate?

I've been constructing a small footprint grid control for Winforms.
After adding a vertical scrollbar I noticed that up and down keyboard strokes on the control move the scrollbar. I added no handler to support this functionallity. Indeed I do not want it. Anyone know where this event resides and what is the proper way to override it?

I'm working on a program that will generate and graph random parabolas with integer vertices. I've got a 360n x360 pictureBox set up and used a for-next loop to draw in a grid consisting of 15 x 15 squares. when I plot the generated parabola I get some unwanted lines/curves. I think this is due to the fact that the (0, 0) point of the picturebox is in the upper left corner and the (0, 0) of my grid is in the center of the picturebox. Is there a way to "move" or "set" the pen position to the first point I wish to plot for my parabola without leaving a mark or trail? Or is there something else I can do? I've tried drawing an invisible line before my g.DrawCurve(plotPen point) but when the DrawCurve is executed I still get an extra line.
Private Sub cmdParabola_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdParabola.Click
Dim x, xPlot, y, yPlot As Single

I'm using VB 2005 and MS Access 2000. I have a process that does some "stuff" with the data, re-queries the database, re-populates the form then displays a messagebox indicating that the process has completed. My issue is that after clicking OK in the messagebox, that whatever textbox the cursor was in prior to starting the process, now has all the text in it highlighted. If I don't show the messagebox then this doesn't happen. And if I don't call the process that repopulates the form controls, this doesn't happen. There's no code in the app that selects the contents of the textbox so is there a property somewhere that controls this?

I have an unbound data grid view. Every cell that has text will display ToolTipText for that value. I'd like certain cells to have no ToolTip and others to have a ToolTip that provides instruction on what the "X" button is for rather than just having "X" display. If anything, for this particular cell, I'd probably rather have no ToolTip. I've tried setting the ToolTip.Text ="" for the cell immediately after creating the row. On other cells, if I change the underlying text value, I try altering the displayed tip text, but only get the text value for that cell.
How can I remove/modify unwanted ToolTips in my DataGridView?

developed my app on a Vista laptop and deployed it on an XP desktop. When deployed the Form and even some controls are resized so text and portions of controls are not visible.Next I moved the project files and VB to the XP desktop and published the application on that machine. Same result, in fact the sizes were changed within the properties of the forms and controls within the project files

I have developed a VB .net application which uses SQL CE as its database engine. It works great so far. I recently added a section to remove unwanted reports which are stored in the database. The app correctly pulls ReportIDs from the table, which the user can select. The program will then delete the records based on the ReportID from the database. I know this records because, for testing purposes, message boxes inform the user of how many records where collected.
Dim SQLDeleteData As String = "DELETE FROM ReportData WHERE (TableID = @ID)"
Dim Con As New SqlCeConnection(DataBaseCon)
Dim DeleteData As New SqlCeCommand(SQLDeleteData, Con)
Dim ReportDelete As Integer = -1
DeleteData.Parameters.Add("@ID", SqlDbType.Int).Value = CInt(ListView1.SelectedItems(0).Text)
noOfDeleted = DeleteData.ExecuteNonQuery
MsgBox("Records Data Deleted " & noOfDeleted)
When the form refreshes to show the user the possible ReportID's, the list no longer contains the recently deleted ReportID. Now this is where I am getting confused. When I go through the server explorer and look at the database there, in the appropriate tables the data still exists. Through the server explorer new query builder, I can still create a select statement to allow me to view the data I just deleted. Does the server explorer create some type of local cache that replicates the database in someway? Are there really two copies of the database somewhere?

I have a Visual Basic 10 program that one forms call another form.. On the called form I have a checkbox object and a 'Click' event associated with it.
My problem is that when the first form 'calls' the second form the second forms Checkbox's click event is called. it only happens when the form.show is used for the first time.

I started computing at college about a month ago and have been learning to program in Visual Basic 2008 Express. I decided one weekend that I would try and make a pretty simple game that I may be able to use for my coursework at some point (I know Visual Basic isn't everyone's first choice for games programming but I thought I could try), I have learn a great deal from doing this but have encountered a rather odd bug in the program.
