VS 2010 ToolStripProgressBar Stops Prior To End?
Mar 13, 2012
Been trying to figure out why my progress bars (one in the status bar when the main window is open and the other in a window by itself before the main window is shown) go up most of the way, then stop till the processing is done.I have refresh in there where the action takes place, and that made it work mostely.Basically I'm loading a file into a string, then while in a loop, I'm processing the file by lines. I have a function that retrieves a line, then it does a:
pbProgress.Value = pbProgress.Maximum - sWork.length
pbProgress.ProgressBar.Refresh()
StatusBar1.Refresh()

How do you get a ToolStripProgressBar to stretch to fill it's StatusStrip when the form resizes? There is no Dock properties for ToolStripProgressBar. I tried setting ToolStripProgressBar.Width and ToolStripProgressBar.Height in the Form resize event but it doesn't do anything.

This is in a RichTextBox. I'm making a string of sports stats and I need to have them aligned neatly in the RichTextBox. Here is an example: str = "12/24 (tab) 225 yards (tab) 2 TDs (tab) 2 INTs" When I use the vbTab constant in place of (tab) I run into problems as the size of the text in each column can be different which makes the tab not balance out correctly.

I'd like you filter some results in a grid, and i want the user to be able to type a value into a textbox, and then the grid will be filtered by that value. I don't need help with the grid or how to populate it. My question is in regards to the textbox; How can i tell when the user has stopped typing so i can automatically load the grid? I thought about doing a refresh automatically in the TextChanged event, but that seems silly since the user could still be typing more characters.

In the members region I declare _Name and assign it the value "NameA" but how do I assign this value conditionally?The idea is that if in some file there's a value set than that should be the default value and not the hard coded one, if non is set the hard coded one should stick.
#Region "Members"
Private _Name As String = "NameA"
#End Region
#Region "Properties"

I want to display an equation prior to solving it. Obviously in MS word etc I can use equation editor to write an equation, but I'm writing my own program.
Is there an easy way to display an equation. Obviously I could use text to write eg as text "a=b^2-3(c-d)/5" and everyone here would have little problem interpretting what I want but I want this to be accessible to 12 year old children.
Alternatively I could try and manipulate lots of text boxes one on top of the other to try and explain what I'm doing
The third alternative I thought of was to write in equation editor export the graphic and then import a graphic.
I'm sure I must be trying to reinvent the wheel - which I believe is the one thing OE programming is supposed to avoid.

I've been working on a program that generates a batch file, then when you press a button, it executes that batch file. There are multiple batch files attached to each item in the list box.
[code]...
The only thing that it does when I press the button, is starts the batch file, then goes to function searchtitle, which executes the batch file again when it finds out it didn't work properly.The button text doesn't change, none of the items are being added to my first list box, and I can't do anything to the window after pressing the button. It constantly opens the batch file every 5 seconds or so.

I would like to develop a structure to maintain my user's text input somehow on each form to allow user to return to the form and see the prior input for potential editing. My app has four forms which accept user input and form a string for output to printer. In the eventuality that the user notes a mistake in the input after leaving the app, I would like to develop a structure to "save" the user input at the form level and allow for repopulating the text boxes with the prior user input. Make sense? I have no idea how accomplish that functionality. Maybe it's too complex for my purposes. What do the pros think?

I'm reading a file and then closing it with the following code, but my problem is later when I start a batch process it says the file is still in use. Am I doing something wrong in closing it? The process was working fine prior to my adding this code to read the file.
[code]...
This rexx exec is trying to write to the file that I read from in the prior step before creating a PowerPoint presentation, but fails becuase of the lock.I'm at a loss. I should qualify and say the process actually starts, but fails in the rexxexec after it starts, it isn't failing on the process start the rexx exec issues a message that it can't write to the file becuase it is in use.

I am using the following code to create a dummy file of a specific size. RemSpace declared as a Long value and is returned in bytes from a separate function in my applciation. I have verified that it returns the correct # in bytes. However, when I execute the following routine, the dummyfile is created, but it never stops the loop. I have to kill it from task manager or it would fill up the HDD. The line:
For i As Integer = 1 To RemSpace
should tell the For loop to stop when it reaches the value of RemSpace, which is a long value in bytes. Here is my complete code.
