would it be possible to check if any notepad or word file is open that contains the word 'test'?I was thinking something like the following.
Dim Process() As Process = System.Diagnostics.Process.GetProcessesByName("notepad")
Dim Process2() As Process = System.Diagnostics.Process.GetProcessesByName("word")
For Each p As Process In Process
If p.MainWindowTitle.Contains("test") Then

I've gone through about 16 hours and two packs of cigarettes trying to figure this out. First a little background. I was using 6.0 up until 2004 when I went to prison. I'm out now, and trying to relearn the trade, using VS 2005. I'm currently porting some 6.0 code from another project, SpyCast Webcam Studio, into VB 8.0. It's disheartening, to say the least. None of the old built-in subs/functions work anymore, so I have to scour the forums to relearn each and every function.The section I'm doing now takes a snapshot from the webcam (Video API --> PictureBox --> Save as Jpeg), then upens the file to upload it to the server via HTTP POST. I've been using this code in SpyCast for years with no trouble, but I spent many hours trying to piece together the right code to open the binary file to read its contents. I pieced together two methods I found around the forums, one using FileStream() though the code I found wasn't for binary files, even though it said it was, so that code doesn't really work. Method two uses Microsoft.VisualBasic.FileOpen() and works better.
Here's the kicker. By the time I run through the rest of the rigamarole of uploading the file, by the time I read it on the webserver, it's *slightly* corrupted. It's a valid Jpeg, no errors, but the picture looks like when I use to watch the Playboy Channel when I was a kid scrambled with weird colors and whatnot. [code] Each "chunk" is basically one "line" of the file. It looks like a single LineInput() return is the text between two carriage returns. Am I correct? I tested this with a flat text file, and it looks true. However, That one input line returns the text or data with the carriage returns *stripped*! ***?!? =( Fine, I have no problem adding my own vbCrLf to each LineInput(), if I were opening text. but this's binary. A character could be Chr(10) or Chr(13), both of which are removed from the original file contents.So I could very well need to use something other than LineInput(), but I haven't found any other examples on the web using this method.

Supposedly I create a file called "hi.txt" and I use Process.Start(filename) to open it. then I File.Opentext(filename), edit it and close it using stream writer/reader, while I still have that file open.
In order to see the changed text I need to close "hi.txt" and reopen it.
Is there a way to automatically do that? Been experimenting a bit but with no luck.

When the main program is doing it's routine, it is looking at, and using, data from the two files.So, when the user pauses the program by opening the control panel, one or both of the files may still be opened. When the control panel tries to open them, it causes an error.(I am guessing that to just tell it to close them will cause the same problem if they are already closed.)

I have a routine that uses windows compression to zip a file. It uses shell32. Rather than maintaining a five second timer for each file, I would like to check to see if the file is closed, not locked, etc., before moving on to the next step in my program. I've searched, and while I can try to open text files, zip files are not text files. I tried renaming the file, but it seems this is actually slowed while files are being added. [Code]

View 4 RepliesIts been requested that my project has a way to limit number of users logged in at one time. I have that figured out but there is a problem. What I have done is that when a user logins in the application creates a .usr file in a directory on the network. If the number of users (value in the database) is less than the number of .usr files another user can log in, otherwise they can not(the file gets deleted at logout or application close). Now the problem is I need to create a way that if the .usr file get deleted the application will close. Is there a way to keep a watch on file and if it gets removed close the application.
View 6 RepliesI have a text file with user names in them on separate lines. I want to check to see if any of the lines doesn't match the exact text im checking for. It doesn't matter what line the text is on, as long as it is in there. If it's not, alert me. Previously i tried .contains() but obviously if a user name is "hello" and another's is "helloworld" it will match both of them.So basically i need to read all the lines in the txt file and if none of them lines contains the specific text im looking for then alert me.

View 5 RepliesIs it possible to check a location for a file and if a file exists then create a new file (+1) in the file name? For example if there is no test file in the C:Temp folder then create a test.txt file and if there is one there then create C:Temp est1.txt and if there is a C:Temp est1.txt file then create C:Temp est2.txt and so on?
I was thinking
If Not IO.File.Exists("C:Temp est.txt") Then
IO.File.WriteAllLines("C:Temp est.txt" + 1, vbCrLf)
End If
I am taking an Intro to Visual Basic class right now. When we do homework, we have to take it into class and put it into a folder that our professor has.When I save it onto my hard drive and I open it from Documents/Visual Studio 2010/Projects/HW Assignment 1, it opens everything perfectly. But on my flash drive, I have the same set up (E:/Homework Assignment 1) and I am not missing any files. But when I double click on the .sln file, it just seems to open the program without my project (display or code) showing.

My question is a rather simple one and to be honest with you, I am not sure if it can be done. Lets say I have a mutli-line text box, is it possible, and if so how would I go about making it so if I clicked Open with > editor I could do things with this text, such as TextBox.text = [file contents]. If it's not possible just let me know and I'll stick with open file dialogs.
