View 2 RepliesI need to write a program to convert in a textbox a number to its roman numeral and written english equivalent. I can write everything except how to get the program to recognize the numbers and convert it into what I need it to.
This is what I have so far, and I'm not completely sure if this is even right, but I can't figure much else out. I've talked to other people who know about this and they aren't sure how to go about it, and my book isn't a big help either.
I would really appreciate any and all help than anyone could give me. I just don't know what else to do and I've been stuck here for a few days trying to learn how to do this...

I'm trying to create a 'lottery machine', I've included the code i've been using below. I've got 7text boxes, ad numbers are between 1-49. I need to stop the duplication and to sort them in ascending order (1-49), i've tired a bubble sort but that hasn't worked, and a 'if, while' process, but i think it might be wrong! I know its a little pushy but i could do with this being sorted before 3pm friday 29 january 2009! I would be so greatful if anyone can even point me in the right direction as i am new to visual basic.

Now I would like to put a wait in after the line:
frames = GIFAnim.GetFrameCount(Imaging.FrameDimension.Time)
ImageAnimator.Animate(GIFAnim, AddressOf paintFrame)
This is so that the animation has time to play and stop and then the rest of the code will display the other picture and the numbers. Is this possible? I tried timer and sleep but I cant get them to work.

I am working on an internet cafe program for the desktops. This is how it works, the login files are stored on a ftp server in the form of txt files (E.G. USERNAMEpassword). The files are opened in the background of the program. Then once the login button is clicked, the two text boxes (passwords and username) will combine together and then in the background will look for the username and password as a single line of code.

P.S. I'm using a textbox.
I would like to know how to loop with textboxs. For example. I would set the text to "Hello" And the loop will send this...
-"Hello1"
-"Hello2"
-"Hello3"
I have tried many looping techniques but they all used listboxs and even modifying them I could not get it to work correctly.

View 2 RepliesI've made a temp converter and i'm looking to get some validation for it. I have looked online, but most do it in a way that i don't want.
I have 3 text box's, of which i only want numerical values and nothing else to be entered into the boxes. However, i would like the validation to run when a button is pressed (in this case, the calcualtion button). I would like a messagebox to pop up stating there is a non-numerical value entered into any of the boxes and for the calculation code to not run.
