I have two images on my VB pictureBox one of it is randomly generated on the picBox(to any location) and the other is a normal image that can move around the picBox area using left right up and down buttons. The problem is that when ever the normal picture gets to the random one, it goes under the random picture and the task is to restrict the normal picture from going into the walls of the random one. when it gets to the wall, top, bottom left and right, it should stop moving.

I am using visual studio 2010, service-based database. I created a simple table and created an edit form for that table. But when I save a row and then clear the text of a textbox (which holds a decimal value), it simply does not let me tab off the text box or save it. I put a ErrorProvider to see whats going on. It says "Input string was not in correct format". But I allowed this column to be null in my table. So how do I fix this error. And by the way, it does not happen for all text boxes.
View 3 RepliesI dynamically create buttons on a form and use the button text as ids so that I can pass that to an SQL query to pull saved data about that button when necessary, but I also use an image over buttons that have information saved about them. What I need to know is how do I keep the text on the button from appearing when there is an image assigned to that button? By default vb.net shows both the text and the image and no TextImageRelation values allow for the image to take precedence. I tried changing the text color to transparent, but the outline of the text is still visible through the image. Is there anyway to keep the text value as it is but just show the image on the button?
View 2 RepliesI have a report that i'd like to display an Image for each record. But not all records have an image. The problem I have is that the last image is then repeated in the next record.
I would like to know how to have any empty field display a default image.
Code I have in report
Private Sub Detail_Format(Cancel As Integer, FormatCount As Integer)
Me.Image21.Properties("Picture") = Me.PhotoLink
End Sub
Photolink is a textfield and Image21 is an Image.

I Expecting result is . When will click the command button.. that time display
one message window, then show result : TRUE,FALSE,TRUE,TRUE
In VB6, you can set the Default property of a command button to True / False, and when you push the enter key, it will click the button for you.

I have a graphics application that uses graphics paths. Code seen below. You can use keyboard characters to display information. When a label is set to visible = false after being turned on for a number of seconds a stray image is generated. The stray images are also sometimes generated when the label is first made visible.
' points p10b, p2b etc are defined elsewhere
Dim GrpPoints As PointF() = {p10b, p2b, p3b, p11b, p5b, p6b, p12b}
GrPath = New GraphicsPath ' 7 path points
GrPath.AddBeziers(GrpPoints)
[code]....
I tried stopping the code from running when the label is set to visible = false but the stray image is still generated but just later. If you want more information let me know.The white arrows points to the stray image that is created just after a label that displayed information was set to visible = false

Form1.Button3.Enabled
End Sub
but its telling me that the property access must assign to the property or use it's value.

I have a form which won't open properly under certain circumstances if a particular Button is set to visible = false. Under the same circumstances if the Button is set to visiblbe = true the form does open properly or if the line of code at a certain place where it is set to either visible = true or visible = false is commented out or not there then the form opens properly. If any one of the 5 phases on my form are turned on then the problem doesn't ever occur but if none of the phases are on then the problem does occur. I just found a fix for the situation but I still am not clear about what exactly is going on.

I have a document management system which creates a report showing people who own which document. There are times where people have 0 documents and in that case I would like the repeater table for that person to not be visible. I have looked around for a while and have not had much luck, I have repeaters nested inside repeaters but if the first repeater is not visible the rest should follow.
