I often think of classes and modules as "global" variables or variables you can use any where in your solution/project. can you make global timers? I basicly want to make a farming like game but the plants will grow based on a timer. So if the player closes that form the timer needs to still tick. So can I make global timers so the timer would not have to start over if the form is closed and reopened?

View 1 RepliesI have (using some examples) created a program which reads from a file, encrypts the content and writes it to a new file. The file can then be reopened in the program and decrypted.Now I am trying to adapt the program to split the file into pieces as specified by the user whilst it is been written to the hard drive. This also works, but when the files are read and decrypted the original file seems to be corrupted. I have been testing it using a JPG which turns out viewable, but is distorted. However the filesize is the same as the orignal after the encryption/decryption process. [code]
View 3 RepliesI am trying to make a program that will compare 2 documents. Idealy what this program would do would be to let the user define key words that he/she is looking for then hit the compare button and have those key words higlighted in both text documents. So far I have 2 button that paste stext into eather box and button that says compare this is my current code for the compare button
If tb1.Text = tb2.Text Then MsgBox("compatible!", MsgBoxStyle.Information) this works great but it only works if the text is exactly the same I just want it to pick up on words that are the same in eather box and eather A. show a message box that tells the words that are the same or better yet B. have them highlighted. I want to do this as simply as possible so if we have to leave out the key words thats ok. I am a big noob and don't know too much about VB (although I came up with that basic code myself thats about all I can do XD) so please bare with me.

How can I set my labels to align on the right even when they have diffrent lenghts. I have a set of labels which are occuring next to each other and also underneath each other. The problem now is that they always align from the left within the label row,but I need them to align on the right as they are showing sums from other rows.

View 2 RepliesI am using the FormLayoutPanel for the first time and I am not able to figure out what is going on.On the form, I have a label that can grow and shrink because the content can change. The text includes the name of the client and that name can always be different lengths in regard to characters. I also have a grid on the form.
As you will see from the attached image, the form that has the FormLayoutPanel on it is showing small and not showing the content of the form. The form is indicated via the green arrow.In regard to the FormLayoutPanel, I have set it up in the following way:
Three rows, one column.The label is in the first cell, nothing in the second cell and the grid in the third cell.The TableLayoutPanel is anchored top, left, bottom, right.
Autosize = True
AutoSizeMode = GrowAndShrink
The Label in the first cell is anchored top, left, bottom, right TextAlignment = MiddleLeft
The grid in the third cell is anchored top, left, bottom, right and also Dock = Fill

I have a datagridview created for my windows app in 2005 and I'm not sure how to get it to grow and shrink, depending on the number of rows that are displayed. The form contains several filters for the user to use in order to get their desired recordset displayed in the grid and therefore, the size of the grid will be constantly changing. How is this usually handled?
View 10 RepliesAny explanation why a EXE in VS2005 would grow from 9MB to 17MB.
