I've got a nice little setup at the moment with how my button is, but for some reason, it shows a black border around it if I show any MessageBox or Dialog that I have, and I can paint over it, but it's impossible for me to do so without it looking wrong.[code]If I click the exit button without the message box code, it works fine!

The INPUT line needs to be fixed. From what I can see, I need to move it all to a single field and use a split to parse it, correct? As I look at the entries on this site, all the code seems to use stream readers. Why would the book not do that? Am I missing something?
I have a Main form, called Main.vb, that is a Parent Form. I have another form called Notes.vb. Inside Main.vb I have a toolstrip with a button on it called Notes.

When I add the required components and click on the button, my app simply disappears, closes, goes right back into a stopped state. No errors, No Warnings, No issues. Nothing. Its as-if there is a stray "END" just before the IF statement. (But there isn't) Its stopping right at the IF statement. My app (THEIR CODE) just makes it disappear and "Stop". The code was working about an hour ago, but now nothing, and thats the only code on the project.

View 3 RepliesI have a view with a few checkboxes that can be selected or unselected. I'd like to always register any change in a checkbox, without the use of a submit button (the user could forget to do it, and it would waste time). So, is there a way to handle this inside the view? Up to now, I've only used the controller to do that job.

View 1 Repliesi have a toolstripsplitbutton, and i want the drop down items to showhide when you click the button not just when the mini arrow is clicked so i call toolstripsplitbutton.ShowDrowDown on the event toolstripsplitbutton.click and to hide, i can call toolstripsplitbutton.HideDropDown but i can't seem to find any property that would indicate whether the toolstripsplitbutton is currently dropped down or hidden..i did not expect this to be this hard but i can't seem to find any indicator of whether or not the list is dropped down.
View 11 RepliesI have a form that has many checkboxes located on a tab control with 3 tabs each tab has checkboxes on it.I have a button that when pressed selects all the checkboxes. That does work and it does execute all that were selected. However there are no checkmarks appearing at all. This worked before! It seems like the more checkboxes I added to the form the less they properly showed f they were checked or unchecked. Now none of them show unless I close the form and reopen it then all of the boxes are checked like they should be when the select all button is pressed.
View 12 RepliesI have some code that does a Find & Replace in some text files, and closes the file when complete.However, when I try to use the Kill command in VB to cleanup these files (they are temporary files) when the program is closed, I get errors that the file is in use by another app or process.Is there a way I can force these files to close first? This also happens when I scan a document using the EZTWAIN.dll Scan to native function.Everything goes fine, but if I try to scan again to overwrite the file, the file is in use.This is happening on Windows Vista SP1.

I have an app, which has a form. a tab is at the center of the form. the tab is a normal tab, and it has 3d style. today, I was adjusting something, and forgot what I changed. suddenly, all controls become flat style. especially, I have datagrid in the form. in the grid, one cell is a dropdownlist style. before i can change how many items to show when is clicked. now, it does not change. now, even I add a control on another form which is in the same app, the style is flat too. what can cause this? very weird.

I've gotten the code I posted a few weeks ago working to export a tab delimited file. ([URL]) Now, I've already converted it from tab delimited to "tilde delimited." My goal is to import this flat file created as an EDI 850 Purchase Order. My ordering system rejects the file, yet it looks identical to other working files. My thought is the encoding / format is wrong.

View 3 RepliesI am trying to access the checked state of a CheckBox from a BackGroundWorker thread. I am utilizing properties and it seemed to work just fine. However, I'm using 10-15 CheckBoxes and I think using the InvokeRequired property would probably be best. I've looked over JMC's thread that talks about how to access controls from the worker thread a bunch of different times and I can't seem to grasp the concepts. When it comes to the InvokeRequired property, I suppose I understand why it is needed. But I'm not sure if I understand it completely.
From the example that JMC provides:
vb.net
Private Sub ResetTextBoxText()
If Me.TextBox1.InvokeRequired Then
Me.TextBox1.Invoke(New MethodInvoker(AddressOf ResetTextBoxText))
Else
Me.TextBox1.ResetText()
End If
End Sub
If I'm not mistaken, this tells us that if invocation is required to access the control, then we access via the MethodInvoker if not, then we just access to directly? So, if I need to check the checked state of a check box, I know I can just put a conditional statement after the Else line if I can access it directly. But, if I can't how would I use MethodInvoker to check the checked state? And then, when calling it from the worker thread, would I just call the sub?
Before, my codes are working properly.. But not..I am getting this run time error. What the error means?
