I'm using visual basic 2008. I have try this code and its work. But the problem is I want to read the text line until it reach line that contain "T". I can only produce the output if I write looping until "T12". I just want to write the code loop until it "T" not "T12".

So, in my vertical scrollbar, the maximum value is 16. In my application, I made a Label to track the scrollbar's value, just for testing purposes. I noticed that when I move the bar to the bottom, the value is 6. And when a [i]release[/i] the button (stop holding it with the mouse), the value becomes 7. Something similar goes when I move the button to the top: It is 1, and when I release the button, it becomes 0. That's a bit weird, but what mainly bugs me is why I cannot reach value 16?
View 1 RepliesI have created a program which opens a file, eliminates the delimiters and save the info into another file.What I need is to reach a specific numbers of characters in the string (which is between 14 and 19 and tells us the date) and to compare it with the current date. If the date is equal or later than today's date , save all lines in to another file. Pease help me to walk through the string and get the substring and finally compare with the current date.

I have a subroutine with a for i as integer=1 to 128 it should send 128 mouse clicks to another application sometimes it does sometimes it doesn't (it works well until it reaches 64 then the numbers go crazy). i suppose that because vb debugger reports that for my form there are 2 threads running (i have a Core2Duo processor and i've read somewhere that multithreading has something to do with the processor).Is there anything i can do to make the cycle reach the 128 clicks? i've tried setappartmentstate to STA, i've tried synclock monitor.enter nothing works, it fails it returns from the subroutine to where it started from and the next time the same story

I am developing an application that will do 2 things:
- connect to a webservice
- Upload/download files through WebDAV.
Seems to work fine, but I am having an issue with debugging. Since WebDAV is installed on the server, i have to publish the webservices there aswell, as the webservice is going to access the file locally (serverside) after upload to the server. This makes it impossible for me to debug the webservices. When i switch to the local services for debug, they cannot reach the file that was uploaded to a remote location (the server). Is it possible to install a local WebDAV server, even if i do not have IIS set up? Just for testing purposes?
Not so much a VB question more of a Net question.Does anyone have a logical explanation as to why the Maximum value of a Scrollbar is impossible to reach by user interaction?The documentation explains clearly the how, it just gives no reason for the why.

I have an inputbox with ok cancel buttons in my class.The user should fill in numbers in the inputbox and if nothing is entered and the user presses cancel or ok, the user get's a msgbox that he should enter something and after this the inputbox should show up again until something has entered.

Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

I have for-next loop that loops 6 times around before exiting. Each time it loops it adds a small number and a space to a string so I end up with a string containing 6 numbers separated by spaces. Whats ends up happening is I get "555 555 666 666 777 777" when I should get "444 555 666 777 888 999". I know for sure it isn't the code that generates or applies the numbers because when you put a messagebox.show at the end of the loop it works perfectly, so it seems to me something is happening to quickly but showing the message box every loop gives it time to catch up. What can I do here?
View 2 RepliesIs it possible to create a loop using a string I am writing a program and I need it to output 3 letters ahead of the letter you input for instance if you input a then it outputs d and if you input u it outputs x, and also the same with capital letters A then D U then X and so on. I have writted the program the only problem is that when I input X I want it to output A but it outputs [ instead I need to create a loop where when I input X it starts the alphabet over again, and I need to know if it possible and if so how will I go about doing so.

I have a this program I have to write but I have no clue where to even start.New Years Ball Drop?Design a program that replicates the Times Square New Year�s Eve ball drop. You can use a picture from the Internet of the ball you wish to use.Functionality Requirements:
-The ball will take exactly 30 seconds to move down the pole
-Need a timer to count down from 30 and reach 0 when the ball is at the end of the pole
-The timer will randomly change colour every few seconds
- When the ball has finished descending, the text �Happy New Year!� will display on the screen
-Need a button on the form that, when clicked, stops the ball drop and timer (so screenshots can be taken). When the button is clicked again, the timer and ball drop should resume from where it left off.
