code snippet that would allow a progress bar to track the input of a text file? Normally I would not bother with this, but the text files are > 10,000 lines long, which is noticable even on a fast machine. The number of lines is variable, so I would assume that one would not use a fixed value to calculate when the progress bar goes 100%.

View 13 RepliesI am trying to 1) write code in VB2010 that will get a JPG image from a Access Database field and write the image to a PictureBox 2) write code which will write a JPG file to an Access Database field. I have already sucessfully coded this in VB6, without fully understanding what I was doing.
Browsing the various forum's I have come across a few discussions on this subject, but due to my complete amerture status I don't seem to be able to follow the logic.

lets say I have a form (form1) with lables a-z which are all designed with default text "0". So they all show 0 on program startup. which is fine. I also have a dialog with 2 TextBoxes; I want my program to update the default text/value on (only)form1 labels x, y and z to whatever was put into the textboxes when i press the OK button on the Dialog, so these specified labels show the 'new' value on next startup. Is it even possible or should I save the values to a file which loads the values in the specified labels on startup?
View 5 RepliesI'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.
how I could check if a certain file is in text or binary format?I'm using VB.Net 2008 Express.

View 3 RepliesI 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 9 RepliesI have an update program that is completely independent of my main application. I run the update.exe to update the app.exe. To check to see if the file is in use, I move it to another file and catch an error if it is in use. If no problems occur I rename it back. At least that was my plan.
Main program: app.exe
Update program: update.exe
This program is used over the network without any services running. So, the users is quite literally running the exe over the network on their machine. I need to update the app.exe when the update.exe has run. To check to see if the app.exe was still in use I was wrapping the following in a try/catch to see if it failed:
IO.File.Move(upddir & "app.exe", upddir & "app.exe.tst")
IO.File.Move(upddir & "app.exe.tst", upddir & "app.exe")
The funny thing is, even if the app.exe is running, the move can rename it to the app.exe.tst without any error. I can even continue on in the application without any errors. I thought I was out of my mind, so I had another programmer look at this and he verified what I said above. So, we tried this wrapped in a try catch: [Code] I put the fileshare as none that, at least I thought it would, show that there was someone in the file. It still continued without any error. Anyone know why I can rename a file in use? Also, is there a better way to do this than what I am doing now?

View 9 Repliesscenario:
-folder x resides on server a, server b ,server c
-x contains same set of files in a,b,c
whenever any file gets modified in a, it should get also modified in b and c as well
similarly b->a,c and c->a,b
my idea of implementation is -when ever any file is modified on a server, compare timestamps and force copy the modified in the other two How should i go for implementing it?
1)how to check if a file is modified
2)how often this check should be done and how this should be implemented should a service be running to perform thi check i want to do this using .NET?
