I am puzzled by a delay in my data appearing (sql sever) when I open my program. (this can be around 5 to 6 seconds). If I open it a second time it appears instantly, have I done something wrong, or not done something. I have connect to a MS access database that connection is instant always.

I know that time delays have been covered before around almost everywhere. however a method that forgoes forcing the GUI to become temporarily non-responsive, is all but a myth, or at least to my findings. i have the need for a GUI program to delay before the next command, however using the current method, detailed following, it causes the desired effect however it dose make it much less polished as when you click anything else on the GUI it goes un-responsive for the directed time. [Code] make a sub called say Tdelay( milseconds as integer) and have it run a loop as many times as the milseconds variable indicates and each time making the thread delay for 1 milsecond and then update the GUI/form in some way, then re-loop.

I have made a PRN file using the "Print to file" option, and now I want to make a VB.net application that will print it directly to a TCP/IP printer which is not currently installed on the computer. Is it possible to achieve this by simply opening a connection to the printer's IP and sending all the bytes of the PRN file to it, or is it more complex than that?

I've done this many time before, but for some reason I can't get it to work this time.I'm trying to get a ContextMenuStrip associated with a DataGridView. I've defined each to the form and in the properties of the DataGridView I've set the ContextMenuStrip property equal to my ContextMenuStrip name (cmsDictionary), defined the onClick event code, but when I run nothing happens.
The program was originally code with a dynamically added context menu but it was popping up all over the place and I wanted to remove that and just let the grid manage it.
I'm working on a project where I make a automatic messenger from VBnet. I want to program a simple one that responds to certain words or phrases. However, I only know the rough basics of If...Then commands. I have a lot of problems:
1. How do I make it so the messages typed in the box actually goes up into the script box when I press send?
2. How do I program a slight delay in the computer's answer?
3. How do I set a name to the computer and to me?
4. How do I make the script goes into scrolling when it runs out of space.
5. If possible, when I type an equation in the box, can I program the computer to solve it and display the answer? I'm a beginner so I don't really know the overall organization of this project. However, I would like it to remain as simple as possible.
I need to get some text that I generate to appear on a label on another form. I can get it to appear on the same form, but can't figure out how to transfer forms.

View 5 RepliesI'm having a slight problem getting my program to load a save file when double clicking the save file.I'm using the Command$() to get the command line argument. I can open a save file by dragging it onto the exe. But not by double clicking the save file (after it's associated with the exe).I though dragging and dropping a file on a program and double clicking the file would open it in the same way, but I guess not.So in short how does file association work and how do I get the file path set to a var when the program loads.
