I am really confused! My program doesn't work if I don't have Visual Studio here in my PC. To test it I have uninstalled Visual Studio. But my program doesn't work though Flash Player is present there (I have used Flash animation in the first form).
To be more sure about it I have installed Flash. But it's not working! That means the Flash animation file (.swf) is not making a problem! It needs support from Visual Studio to start. Doesn't it mean that some files are not attached with a setup file as a result it needs Visual Studio to run? Let me tell you how I create a setup file of my program.

The program has errorhandle and write log function, however, it could not catch the error message in the program.

Suppose I save a file as *.tar (this extension is my own making) using a vb6 program. Now when the user clicks this file, the window asks 'with what program to open this file' and he/she selects the exe of my program. Now I want to pass the name of file clicked to my program. Like when we click *.xls file, the exe of Excel program knows which file has been opened or clicked. Is there a way?

I know I gotta get a book or something because things are just way too hard for me. But before that happens I have what I think should be an easy question.
I want to create a variable in xaml, the angle that a control is currently at, and then use this variable in my VB code (event handler).
Or even better can I, while in VB code, check the current angle a specific control is at so that I can add to the number when setting the new angle?

View 2 RepliesSo I'm pretty new to operating in the VB.NET environment, so this might be really basic. But my issue is this. I am writing an application to get the next available computer name within active directory. I have an VB program that queries active directory and finds the next available name. I also have a VB form that will allow you to set the name of the computer and which Active Directory OU it should go into. I would like to have the program that finds the next available name run right away when the app is opened, and then pre-populate the computer name field in the VB form with the next available name from Active Directory. However I'm having a very difficult time finding how to do this. I've tried adding the first program in the ApplicationEvents startup area, but I'm not sure that it's running, and I can't find how to programatically pass the result from the first program into a textbox field.

View 2 RepliesI'm trying to create a function that searches up a WebControl's parent-child relationship (basically the opposite of WebControl.FindControl(id as String), but looking for a specific WebControl type).
Example
I have a user control in an ItemTemplate for a GridViewRow. I'm trying to reference the GridViewRow from the user control. The user control may or may not be inside a div or other types of controls, so I don't know exactly how many parent's up to look (i.e. I can't just use userControl.Parent.Parent). I need a function that will find the first GridViewRow that it finds on the way up the parent-child hierarchy.
I am developing an VB.NET application that reads data from the serial port and tcp socket, then I'm processing this data and store it in Database server. This application will be started all the time as long as the computer is started. On the server there is installed an apache server with some php scripts representing the "visual interface". From there the users can see the readed data from the VB app. The need is when an event appear in the apache server (such as button pressed), some data to be passed to the running VB app, and eventually trigger an event on it. I've considered some variants like start an timer that reads continuously some tables from the database that the php script writes onto, or read an xml ot text file, but I think that this may slower the communication and it is a source of exceptions or errors.
For example: An user opens a webpage, just to say test.php. On the page there is a button. The user pushes the button. The result of pushing the button has to trigger an event on the VB app and cause sending data trough the serial port or tcp socket. OR - The VB app has a timer that scans for pressing the button on the test.php.
I would like to make my program do nothing for a few milliseconds.
View 17 RepliesIs it possible to pass data between a MODULE in Access and a VB2008 app?
To be more specific, suppose a VB app calls a MODULE in a access DB and the job of the module is to count the number of records that have "Joe" in a column. I know this can be done with a SELECT within the bindingsource BUT in some instances, it is much faster to pass the task to Access and return the result.
So - can an Access MODULE RETURN a value back to a VB app?
Can I pass parameters back and forth between a Windows Service and .NET program? For ex: I want to pass a compressed/encrypted byte paramater to the Windows Service, who then decompress/decrypt it and return back the decompressed/decrypted bytes.
