Use The Information And Connect, Otherwise, Quit The Program?
Jan 31, 2011
So i am writing something for work, and i was roaming the internet to see how to do it in vb.net, but it seems to really not have many hits. vb.net doesnt recognize Declare and all information points to things that say Private Declare Function [info]What i was wanting to do is to check if a computer has a DSN card in system DSN's, if it has it use the information and connect, otherwise, quit the program.
Do you know where i can find how to do this? I just need to check for the existance, i dont need to make them.All of my search results, while seemingly useful, were not written for vb.net I want to get something up here specifically for vb.net so we can get more search hits. i find more information, i will post it, but it doesnt seem to be going too far in the vb.net department, as it is in .net

This runs correctly, but Excel remains active after close.
If I don't create the range objects below, everything seems to work (with no output of course). Does anyone have any idea on how to keep Excel from staying in memory. Also... in the tests I'm running, I do not make the application visible.[code]...

im trying to make a program that connects to several websites and parses some information out and then add the information to a listview list.The listview have 2 columns: Site and Nuts. So i load a bunch with urls in the site columns (that isnt a problem) but the problem is to take 5 websites at the same time and connect to them and then write "OK" in the Nuts columns.
In VB6 i could easily make 5 sockets, and then move down five items in the listview, save each of the listview text to a variable and connect to each variable with different socket, but how i add the information to the column "Nuts" is also a challenge in vb6. In the other hand, in vb.net i haven't yet got the skills to do so.

I have an external (3rd party) EXE which I start from my app, which reads data from the user and creates a corresponding registry key with the information, then exits. I then need to read those registry values from my main application.
I start the app with:
Process.Start(My.Computer.FileSystem.SpecialDirectories.Temp & "GatherInfo.exe")
I need to read those registry values AFTER that EXE has quit - so I know they've been created. At the moment I'm just making my main app sleep after that process has been started:
System.Threading.Thread.Sleep(1000)
And then checking for the reg values. I'm worried this won't work for different users however, as the speed of the computer will determine how long the process takes to start and exit.

My program opens an excel file with excel.application's .visible=false. If the code is running and I manually open any excel file the excel file being used by code will then open up as well (making the .visible=false useless). Then at the end I use the excel.application's .quit to make sure that instance of excel quits, but it will quit every open instance of excel (even ones not opened by that code).Is there any way around this? to make sure it does not appear when other files are opened, and to make sure it only closes that one instance of the excel application.

I'm trying to create an excel file and load headers into the first row and then save the file to the local computer for later use. All of that works fine, but for some reason the "EXCEL" process won't quit. I have read through the tutorial written by Mike R and I have even tried just copying and pasting the code from the tutorial into my project, but to no avail. I should also note that I have not yet tried the "Extreme Measures" listed in the post, though at this point I am tempted to.
Code:
Dim ExcelApp As Excel.Application
Dim ExcelWorkBook As Excel.Workbook

I have a SSIS package that runs every 5min.My package has an error routine in the onError event handler but I don't want it to get in there.So in fact, the package should just exit / close / kill itself without any warning or error.Preferably this should be initiated by the script task (vb.net 2008)

I want to store some information of the form in such a way that if the user quit/exit the application it stores the information. When user runs the application next time the information should be available to him. It also involve the restart of the computer. The application is in vb.net 3.5 framework. The one way that i can think of using flat files and encrypted data, but i can not do this. I do not to store any kind of data on client side and I can not store this information on server side. The problem is of getting client machine information and storing it on server.

I'm making an installer that needs to have information stored inside the exe itself.I cannot use my.settings because it is stored outside the application and if it is changed and the exe is moved to another computer it will reset to default.
And I cannot use resources since I cannot add/edit resources after the application is build.
Is there any way I can store and change info even if the application is moved to another location?

To start, I should probably mention that I have almost NO knowledge on coding, MySQL, or anything in that category. I have watched some simple Visual Basic tutorials and I am attempting to make a software in Visual Basic 2010.What I need to do is connect all of the users of the software. For example, in the software there will be a label. When somebody using the software enters something into the label using a text box, I want it to show up for all users using the software. I am going to take a guess and assume that a MySQL database will need to be connected?
