I'm writing a program in VB.Net and loading the info into a SQL database. Debugging it works fine on my machine that I am programming it on, it connects to the database and runs through all the info perfectly. However trying to get it to run on another machine it will not connect to the database. I realize the reason for this is the connection string, it's looking specifically at the file directory for the database. How do I change this so that it will function on any machine. The program is only intended to run on one machine at a time and not over the internet.

View 8 RepliesI'm making a program where the user fills out info, then they click one button and the program takes a screenshot of the form, then they click another button and the screenshot gets saved. I'm having a couple problems with my code though. For one, I'm trying to make the screenshot go to an invisible picturebox to make saving easier, but I cant figure out how to make the image go to the picturebox. The other problem is that I want it to automatically save without showing the dialog, but so far, it won't save.

View 2 RepliesI have a program that at one point will open word and export some info. That works perfect, however I have just noticed each day I have a number of winwords open (can only see them in task manager so they are hidden). It appears that everytime I start the program it opens a hidden winword session. It has nothing to do with the code I have on the form, it opens before any code I have written is executed.

I have a requirement where I have to pass some values into the next page via querystring.This querystring is coming from third party and they need to have it on the otherpage for some analysis. I just do a response.redirect and add the querystring that i recieve from them to the other page.

However I am having a really hard time decrying it back.[code]All I am trying to do is to create a program that will decrypte these file with an upload button. Our system encrypts the files to prevent operators from changing the results, we need to trend the data. However it will take way to long to use the online tool provided with the software. A desktop tool will save us much more time. The files generated are 70mb and up.
