I have a black form with wihte letters in it. All the letters are each label.Fore xample, label1 is for the letter C, label2 is for A. Now I want for the form loading to make label1 appear, then wait 500 miliseconds, then label2 appear, then keep waiting 500, then appear. etc. that's 15 labels.so I did
[Code]...
Is it possible to change to colour of letters as they are typed.I.e
Piece of text says
"Hello World"
when user types "H". The "H" in the original would change if matched and then so on and then when "Hello" is matched it would change to another colour.
How would I go about doing flashing labels, that go between Red/Green ever 200 or So miliseconds?

I have two Buttons, button A and button B. After 100 clicks on button A a pictures is displayed and after 10 clicks on button B another picture is displayed. I wanna have two different timers as to timing each response (button a or button B respectively) without these two timers to be timing both these responses. I try to do this for over one month!

SendMessage(x, BM_CLICK, 0&, 0&)

I'm writing a simple program that takes a screenshot of tab1 of the GUI, then takes a screenshot of tab2, then tab3, etc. I've got the screenshot code down pat, but the problem with my current code is that it's taking the screenshot of each tab before the screen has a chance to fully redraw, so the resulting images are screwed up.Is there a way to get the program to wait for each tab (and all the controls in it) to be fully visible before each screenshot is taken?I'd like to avoid using a timer for this, as the screen redraw speed will vary depending on the user's computer, and the contents of each tab, etc.[code]
View 2 RepliesI know I'm not the only developer experiencing this issue but only within the last month I started receiving Visual Studio 2010 hangs while running running a simple ASPX web project within the IDE. On stopping the execution or closing the web page VS2010 hangs and becomes completely unusable - stating that VS is busy. It never returns and I have to stop the DEVENV process, resulting in a complete shutdown of VS.
Until now (1 1/2 years) I've been developing a Winforms application with no issues, other than VS2010 IDE errors that have been documented and I've been able to work around. Now, like my Web project, I am also experiencing the same hang but not as frequently. Other documented cases is this forum don't apply in this case since I'm not working with an IIS web site.
Additionally, in reading the forum messages I notice this issue has been around for years and has caused a great deal of grief and delay to many development projects. I'm running Win7 Pro, VS2010 pro on a Pentium Dual-Core CPU 2.20 Ghz with 4 GB memory laptop running in 32 bit mode. I'm very concerned at this stage of the process to upgrade to VS2010 SP1 since I've read too many horror stories online and can't take the risk of affecting the only support environment i have for Winforms application that is currently in production
I have things set up so that the program is ready to start logging ,only when Recieving=true.This is controlled with Button1. So I click button1,Serial port is open and waiting for some signals from the Dyno.When 1 signal come it put a "1" in TextBox1 ,and for the second a "2" and so on. Thing is sometimes it starts right away, like I want it to,and sometimes it lags a fraction of a second, even though the Port is open.When it lags there are already 5 to 10 signals gone by before it starts logging 1,2,3,...and so on. Sometimes it don't start at all.Then I have to close and re-open the form and it works,but with lagging on the first "set"
"Textbox1 > 0 then" triggers a timer (not seen in this code)that samples Textbox1 once pre interval and writes the value to a listbox. On the upside as soon as a "1" is displayed in textbox1 the timer starts like it's supposed to.I noticed this behaviour before I added the timer and besides the timer has nothing to do with the signals coming from the SerialPort. I have my form setup so I can run "sets".Run one "set"...save...reset...run another "set" ...and compare.It's always the first "set" thats off.If I run multiple "sets" the first one is completely "whacked", and the rest are consistent.
Think this could be the SerialPort lagging,or code problems?

Im making a login system that encrypts and decrypts the username and password. My encryption code is:
Private Shared Function enc(ByVal targetString As String, ByVal maskvalue As String) As String

The enc function works for both encrypting and decrypting (I've tested with a MsgBox alert. The problem I'm having is when the program loads, it reads the file and decrypts it. However, instead of properly working, it returns one character in the first textbox and nothingin the other without any error being thrown.

I have a problem with an App I am writing that lists information about various media on your computer and lets you launch it right from the app. My problem is, when launching an intensive process, like a game for instance, it is desirable to shut down the app to not hog precious resources. Here is the code i have so far...

This code works fine, but for one small detail. The app exits before the desired process starts, thus cancelling out the process all together. My question is, how do I get the app to wait for the process to start before exiting?
