I did some research (mainly in the Drawing namespace) about animated GIF files and I know you can see how many frames are in the specified GIF using the GetFrameCount method, however how I can access each frame directly/loop through them one by one. This is my first time trying anything like this and I can't seem to find the right methods, classes or information. I'm not even sure if this is possible using the .NET framework.

I have been developing an application for quite some time now. I have decided to create an mdi parent form to hold all the windows I have done so far. Is there an easy way to implement the mdi parent/ child associations rather than to go and declare them each one individually.

View 4 RepliesIm trying to work out how to do a project called pig latin in vb.net 2003... so far I've gotten it to work for a single word. If there are spaces it still acts like there is only one word with the rules (ex: monkey stuff = onkey stuffmay) I know that i have to figure a way to seperate the string up if there is a space and do the rules for pig latin for each word and then make it show up in a message box but I'm stuck... as soon as i can get it to split I have to calculate the number of words starting with a variable and percent of said words and so on which shouldnt be hard with an If Then statement

View 2 RepliesI have defined 5 variables T1, T2, T3, T4, T5 As Double and set them all = 0. On a form I have a enter information button. Each time the button is pressed I want to assign a different variable, to a text box input. For instance, If I enter 1 that will become T1, and then if I enter 2 and press the button again, that value becomes T2.
I have tried
If T1 = 0 then
T1 = textbox.text
End if
If T1<>0 And T2 = 0 then
T2 = textbox.text
End if
I have tried to use 'else' statements and all kinds of things like that to no avail. I can get the first two variables correctly assigned but three is impossible with my current understanding. Is there a way to do this, or do I need 5 buttons, so that I can control which variable is assigned? To be correct my intent is to create an observation with three variables each time the button is pressed.
For example, the first button press will result in three variables being assigned a value other than 0; they are T1, B1, and R1. I have just begun to understand the concept of arrays and am wondering if that may be the way to go in this situation. I was just going at this in a newbie way I'm sure and trying to handle each variable type individually, and figure out all the T* variables and move onto the B* variables.
I have 42 RichTextBoxes (RTBs) and I would like to add my ContextMenuStrip to each of them (which I have already done), but the problem I am having is when the application is running and the ContextMenuItem "Copy" for example is clicked, I can only make it copy the context of one of the RTBs, when I would like it to copy the contents of any individual one. So as I mentioned, I have 42 RTBs, but I am having trouble getting the contents of the focused RTB. The below code is just copying the 1 RTB and when I Copy on another RTB, it copies the contents of RTB1.
I originally started out with like so, but is just for the one RTB and when I add more than one in the code below it's even more of a disaster..
Private Sub Copy_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Copy.Click
RichTextBox1.Copy()
End Sub
I tried using this, but I was not sure how to add the copy function into it:
Private Sub Copy_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Copy.Click
Try
For Each itm As Control In EnumerateAllControls(Me)

View 11 RepliesI made an application that writes to a text file in csv format, and on another tab, there is a listbox where the user can click the "View Report" button and it will display the information from the text file in a list box. Right now, I am really pleased with it because I was able to use "split" to get all of the separated values on there own individual lines.Now I am wondering, is there a way that I can display one entry at a time in the list box, and then maybe implement "previous entry" and "next entry" buttons so that the user doesn't have to scroll down through the entries to view them, they can just hit next entry and it will go to the next line in the csv text file and display the information from there? I have tried doing it a few different ways, here is what I have so far for the "View Current Report" button:
Private Sub btnViewCurrent_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnViewCurrent.Click

I've been racking my brain trying to figure this out. I've done a ton of searching but I can't find what I'm looking for. Right now my program gets a image file, converts the image to 4 colors (Black, Red, Yellow and Green), then converts each pixel to a number for that color.This works great, but now I'm trying to do this for an animated image, but I need to be able to loop through each frame, but I haven't been able to figure out how to access each frame of the image.
