View 3 RepliesUsing windows xp. Sp3. over 100GB free on each disk that I use,Attempting to unzip a file that has directories in it. I want all files in the zip file to go to one directory ignoring the dir structure.I'm using VB to do this. Problem is that the process hangs at the same place on 2 different machines. Any ideas. Code below in vb and the results.Executing the same command line from DOS works correctly.unzips 72 files then hangs.
Code
newProc.StartInfo.UseShellExecute = False
newProc.StartInfo.CreateNoWindow = True
[code]....
Here's where it stops. And shows the dir struct of the zip file NDDF Plus DB. i've got a screen shot of the dir structure and files. basically it unzips the files in order of the dir structure and stops above.
Running into a situation when user searches for orders of customer for past 4 years. As the DB query takes a long time, I want to show a pop up box just stating 'please wait. quering for results'. so when they start their search I want to show the message box until the results are obtainned and at that point I want to close the message box.My current way, I know is incorrect as the pop up box locks up and states (not responding).Would using a background worker be an over kill, or should I go with a progress bar?
View 1 RepliesThis is going to be a strange issue and I don't expect an answer,.I'm using Ghost32.exe to image HDDs within a Windows PE environment. With the release of WinPE 4.0, we can now use the 4.0 .NET framework. So in order to capture any errors that Ghost reports, I'm redirecting the standard error stream so I can review it later.
But, when I implement those two lines of code (highlighted below), the application crashes.I've implemented error logging with the UnhandledException event of the application, but it never fires during this error. All other errors fire, but this one does not.So I ran it in normal Windows and I receive the following error:Quote:The system cannot find the file specified
But when I comment out those lines, it opens just fine. So I'm a little confused.

I am creating an application for learning purposes. I am using this: process.start("iexplore.exe"); That is working fine. However I would like to be able to tell when the page has been loaded all the way. I would like to know how to tell if the application is done processing or not, that is my main goal. If using the webbrowser control you can use the webbrowser documentcompleted event.

It uses reflection to get a listing of all of the processes it is capable of from a specific folder, and starts them via reflection with a known start point (all of them have a method called "Process").

View 7 RepliesI have created tool which performs batch processing on files that are selected. The sub routine I have defined in the code, now I want to implement a way through which I can select actions that I want to perform and then perform the actions. For example the list has multiple actions, like Open, Close, SaveAs, Resize, Color Correct etc. I should be able to select what all I want to do on each file and then perform this actions. Someone suggested me using delegates for this, but I cant use that since all my functions have different parameters. Ither option I had is to use a nested IfElse or Switch to determine which action is selected and call function according to it, but thats to heavy I think, is there any optimized a better way to do this.???

Itemlists is a global lists i retrieved from database, everything looks fine to me but when i run this program, I found that the threads are inserting one records 9 times into the database(I have 9 threads in total), which makes me think that maybe i need to specifically assign 1/9 of a list to each thread? Is there another way to do it which doesn't require the splitting of the list, if not , how do i split it then assign?

View 1 Replies2008 Array Processing and Sequential File Processing
View 14 RepliesIm a college student and this is my first programming class, i am having extremely diffcult time with arrays and sequential file processing. Im not asking for the whole program, just something to get me started and hints along as i progress with it. Please help me get started on my program, its due in 2 days.
Here are the requirements....
1. The program must input any number of individual�s last and first names using two separate textboxes.
2. The array of names must be sorted by the last name using a bubble sort. You must code the sort.
3. The program must be able to recall the names from the file and add to the existing list of names so that more names can be added to, sorted, and written back to the file in sorted order.
4. Sort in ascending order: A to Z
5. All names must be displayed in a listbox in sorted order when the user wishes to see them.
6. In the listbox the last and first names must be separated by a comma and a space. Example: Smith, Mary
7. The user must be able to search for a name in the array, using the binary search algorithm. You must code the search.
8. Do not use module-level variables. Instead you may choose to use Static.
9. The program must be designed using Visual Basic 2008

I have an issue with creating a VB program. I reference files on my computer that are displayed in a webbrowser in the program. The issue comes when I install the program on another computer because of the file path. The program is looking for the files on the computer I created the program on because of the file path, instead of looking for the files within the program resource files.
For example, I created the program on Computer A and referenced File "C:ComputerAMy DocumentsHelp.txt"
Once installed on Computer B, the program doesnt display the image because it's looking for "Computer A" in the file path.How do I correct my programming so that the files are universial and can be found on any computer the program is installed on?

View 2 RepliesI am writing a manager for an app that we use at the office. I have successfully written launching, monitoring, and managing number of instances using the process class.Each file is the data output for one study. Each of the 2-8 instances of the application will run 1000 studies overnight. The fault would be that the file stops growing. I cannot just check for that, because it also stops growing when it done with one study. I need to be able to determine which files are being written by which threads (or vis-versa where i know which files are 'running' and need to see who owns them)?
View 13 RepliesI have a program that processes files in a special subdirectory and the program processes the files based upon the "Type", i.e., "Text Document". If an application, such as a text editor, installed onto the system, the "Type" may change to suit that application. For example, I recently had one change the type from "TXT File" to "UltraEdit Document (.txt}". Yes, the squirrely brace was on the end, don't know why. Well, after this app was installed, my program found no files of "TXT File" type to process even though the subdirectory was full of filename.txt files.
So, how can I get the code to look at the file extension, not the Type? A few lines of the code are shown:
