I have a service ticket management application and users want to open several ticket details on a tab in a MDI frame. Since this application has to communicate through Web XML service with other company, it takes around 15 ~20 seconds. The users most complain is that he needs to wait until a saving process is done. Cursor is working while data is being saved and other can't be done
View 3 RepliesI use the 'Process' object to run EXE from my application. It works fine when it run on Windows XP and 2003. When it run on Windows server 2008, it hangs up: the process is stayed in background but never returns. It never goes ahead for the next commands. What could be the reason? [Code]

I am trying to write a Windows Script that will allow me to monitor the following: That 2 x seperate but specific processes within Component Services "Running Processes" list are currently running and have not reset within the past hour. If I already know the PID, then I can retrieve the CreationDate (I assume which I can use to check for restarts? or is this the actual process creation/installation date) for each specific process, however if a restart occurs the PID will change and my script needs to know what the new PID is without me telling it!

View 3 RepliesI have a web request that can take 30-90 seconds to complete in some cases(most of the time it completed in 2-3). Currently, the software looks like it has hung if the request takes this long. I was thinking that I could use background worker to process the webrequest in a separate thread. However, The software must wait on the request to process before continuing. I know how to setup the background worker. What I am unsure about is how to handle waiting on the request to process.Do I need to create a timer to check for the results until the request times out or is processed?

View 15 RepliesI am developing a solution in .Net utilising the VMWare Web Service API to create new isolated virtualised development environments. The front end will be web based. Requestors input details for the specific environment which will be persisted to SQL. So I need to write an engine of some sort to pull the data from SQL and work on the long running task of creating resource pools, switch port groups and cloning existing VM templates etc. As work progresses, events will be raised to write logs and update info back to SQL. This allows requestors to pull data back into a webpage to see how it's progressing or if it's completed.
The thing I am struggling with is how to engineer the engine which will exec the long running task of creating the environment. I cannot write a windows service (which I would like) as we work in a very secure environment and it's not possible (group policy etc). I could write a web service to execute the tasks, extending the httpRuntime executionTimeout to allow the task to complete. But I'm keen to hear what you guys think may be a better solution to use (based on .Net 3.5). The solution needs to be service oriented as we may be using it on other projects within our org. What about WWF, WCF? I have not used any of the newer technologies available since .Net 2.0 as we've only just been approved to move up from .Net 2.0.
I have written a program that searches a bunch of urls and pulls out information that I need. The program works to an extent. Everything codewise works, but it seems like I did a sloppy job of pulling the code together. After about 10 minutes of running, the program just becomes unresponsive and I have to close it through task manager. I've seen it range from 100k to 350k in memory useage. It also uses about 80%+ cpu usage at all times. I hope someone might be able to see something that I forgot or did wrong as the program is meant to run almost full time, executing parts of code on certain days/times.

I've got a common search button in my app that has the typical static magnifying image displayed on it. When the user clicks it I want the button's image to change to the animated search, to inform the user that the app is doing something (searching the database). Then when the search process is complete, change back to the static search image.
[code]...
When I comment out the line to change the button's image back to the static search image, (as stated above), and click the search button, the app actually performs the search, then when the search is completed, it changes the button's image.
Apparently VB or .Net is performing the under-the-hood process before the display/paint process, even though that's not the way it's coded. give me some insights on how to fix this, AND also please inform me of why this behavior occurs so I can try to avoid it in the future.

View 6 RepliesI'm currently trying to write a football simulator but am having issues with the computer becoming unresponsive. There are long lines of code (several thousand lines) that are executed over and over as one run of the code is equivalent to one second of game time. While the game is setup to be like Football Manager where you watch the game live, there will also be cases where the entire game is simulated without you watching. When doing a full sim of a game, I just have a loop which executes the code block 7200 times (games go for two hour roughly).
At the moment this takes about a minute but even when I get it down to the desired 5-10 seconds or so, I dislike the fact that the computer becomes completely unresponsive during this time. In a round there are 9 games and you'll be simulating without watching 8 of them. You're looking at 1-2 minutes of simulation time or possibly more. I can't have a loading screen that long! How can I program the game so it runs these simulations yet the game still remains responsive? It'd be fine if the user could muck around in the menus and stuff while the simulation runs.
I am running a test program for VB.NET, and it will simply crunch a million numbers in for loop. I've linked a variable implying the progress of the for loop with the progress bar, but it seems that when I run the program, the progress bar does not update itself. The bar itself has only value 0-100 as input (as stated in the document) and I've tested it without using the for loop, and it works.
View 2 RepliesI am almost sure this isn't possible but it's worth an ask... We have a .NET DLL that is being called from our VB6 application. The VB6 app runs in a 32 bit process so the DLL runs in the same process (it's compiled as any cpu) Therefore when I do my ODBC Database access in the DLL is will only use a 32 bit driver, as this is what it thinks it needs (for the record the DB is Pervasive PSQL)
My problem arises when the application runs on a 64 bit machine (when only the 64 bit ODBC driver is installed) as it can't find a suitable driver to use. So is there a way to force the .NET DLL to run in a 64 bit process (compiling as x64 doesn't work because register for COM Interop is not allowed) This isn't necessarily an issue at this point in time because I can install the 32 bit driver, but at some point in the future I can imagine that 32 bit driver may not be available so I will be up the proverbial creek.
how to run a process as a child process?

What my program does is load a file (password list), then progressively reads each line of text in the file whilst writing each line to a new file. After X amount of lines have been written, it should start writing the lines of text to a new document until the initial password list has been split into X amount of password lists. The problem I have is that after hours of tweaking, all I can get it to do is write either blank ocuments, or write all of the lines to only one file. I really need it to be able to split into multiple files, preferably at runtime rather than loading a whole text document into the program in a textbox or array then writing it to new files.Below is the source:

I have a DLL that copies an Access database, opens it, reads it, and then closes it. The second time through it is unable to copy the Access DB because the EXE has an open handle to it. The EXE does not reference the Access DB at all, it just has the open handle because it calls my DLL. After I close the DB, I would like to terminate the EXE's handle to the Acess DB. BTS - I wrote the DLL and it is my Access DB. Another company wrote the EXE and I can not make any changes to it.

I am attempting to make a piece of software that monitors a 3rd party process for injected code. I successfully made a program that uses readprocessmemory from kernel32 to search for strings in a process. My problem is that the process I am attempting to monitor is running as system and provides an access denied message when I attempt to query any information about the process. Including process.handle and process.modules. Are there any ways I can get this process' handle?
