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.

View 8 RepliesI'm using Visual Basic 2008 Express Edition.I'm working on a class. At various points, I want to insert a delay between executions of the code. Nothing terribly large. Around 50-200 miliseconds. It doesn't seem like much, but it makes the program run better. I'll probably randomize the length of the delay later between those two marks. So basically the code would go...SomeFunction()timer delaySomeFuntion()I have the timer declared as
Private tmrTimer As TimerAnd each place I want to use it, I simply redeclare it. Or I might add it to the constructor of the class. Either way. Just thinking adding it to the class constructor would probably be a better idea.

End SubUnfortunately, I get the error "Handles clause requires a WithEvents variable defined in the containing type or one of its base types"Now remember, this is all contained in a class, so theoretically speaking I can simply move the class file from project to project and reuse it, without ever having to worry about how the class works. Reading through the Timer specifications, I probably need to do some cleanup on the timer after I use it. Am I correct in this?
I have a Nag Screen that I am creating, and I am wanting to create a delay before the OK button is enabled allowing the user to proceed.
Is it better to use a Timer event or would a 'For I = 1 to 20000"
loop be the better option.
All this timer would do is Enable the OK button, thats all.

View 7 RepliesI am currently creating a program to send keystokes to a program at certain intervals. I need the thread to delay between keystrokes, and i need to be able to have the user input the amount of delay from the GUI via textbox. I have it running perfect with Thread.Sleep(), but it just isn't consistent enough. How can I code it to be accurate to roughly 5ms up or down? thanks, and here is the code. This is in VB 2010 by the way.

View 12 RepliesI'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.

View 20 RepliesI am very very new to VB.NET and would like to ask a simple question. I want to create a vb.net program and allow visitors to a website to download this program. However, I prefer not to have visitors download a zip folder. I would like to have a program that just gives a prompt to save in a selected folder, once the saved file is selected it prompts the person to download, and then when finished prompts the person to run the program. The reason is twofold:
1. I don't like the extra step involved with unzipping the file. and 2. I don't like the visitors having to look for the "main" file program within the new downloaded folder. So is there any way to have just one file for others to download without having it in a zip folder?
I'm trying to create a program that installs required .dll's for a program due to a clean install..What I need to do is Get a value in the registry and use it for the program files path.. but I've noticed some pc's don't have the same configuration because of the version the user is using. Anyway This is what I have so far:[code].....
What I'm trying to do is find a registry key called "SoftInstallPath", if found I need the end of the path to goto the new directory(new_dll) not the old one (dll).. and if "SoftInstallPath" cannot be found.. I need it to find "ProgInstallPath" and use it instead and do the same thing.By the way I'm using Visual Studio Professional 2008 on a Vista x86 machine.Also error I keep getting is: Warning 10 Function 'FixPath' doesn't return a value on all code paths. A null reference exception could occur at run time when the result is used.
