Copy From, Erase, Then Paste Back Into The Clipboard?
Jul 26, 2010I have to automate a program that is outside of my control. The way I'm doing this is to use SendKeys.SendWait("keys") to the other program. The problem is, there are multiple fields that might be active and no way to select a single one with confidence. The fields are all different lengths, so my solution is to copy something really long, copy it to the clipboard, and look at the last character that made it though, so I know which field is selected in the other program. This overrides the clipboard, unfortunately.

Erase Or Write ID3v2 Tags To MP3s?
Jan 14, 2011I already have code to read ID3v1 and v2 tags. That's not the problem. I open an IOStream, locate the ID3v2 header and pull the bytes out. Handling unicode was a bit of a sod, but I got it working.
What I don't understand is how to remove an ID3v2 tag or write one out. ID3v1 is easy - just truncate the file, then append some bytes. Simple. But ID3v2 tags don't have to be at the start of the file, do they? It's conventional, but by no means mandatory. If I just crop the entire ID3 out of the file, and close the gap, will that work? And then, to write my own tags, should I just write the bytes to the front of the file? Or do I need to update other bits of the file so the player will know where the audio data has moved to?
Also, do I need to use unsynchronisation? How can I tell if I need to?
I've looked on CodeProject; I've googled; and I've read the specification on id3.org - which, by the way, is less than clear! For example, it says that the "Extended header size" can be 6 or 10 bytes in length. So um....how am I supposed to know which one? Is there some magic way of determining how many bytes this value is being stored as?

View 2 RepliesVS 2010 Painting When To Draw/erase Snap Lines?
Oct 6, 2010I have started to work some more on my 'shape editor'. If you're not familiar with it,ust imagine the Visual Studio form designer: a 'canvas' (the form) with a bunch of 'shapes' (the controls) that can be selected, moved, resized, etc. I have just finished implementing snapping between shapes and the canvas boundaries. But now I am having some slight issues with painting the snap lines.Just FYI: this is what I mean by snap lines:The blue lines that indicate that the 'buttons' are snapped to each other, and a purple line indicating that button1 is snapped to the boundary.
My shape editor is based loosely on jmcilhinney's 'manipulating GDI+ drawings' codebank entry, and a central idea in that post is to only draw what is necessary. In other words, when I move a shape I could re-draw the entire canvas, but it is much faster and smoother to only re-draw the old and the new location of the shape. Since nothing else has changed, I don't need to draw the rest. So, I simply invalidate the old bounds and the new bounds, and even with a lot of shapes all moving simultaneously it still feels very smooth.

Use .next (random Numbers) To Randomly Select Something From A List Of Numbers But It Can't Repeat The Number?
Aug 16, 2009So how would I use .next (random numbers) to randomly select something from a list of numbers but it can't repeat the number?I could do:
dim num as integer
dim r as new random
num = r.next(1,5)
if num = 1 then
elseif num = 2 then
etc.
That wouldn't work because it would repeat.If I donwload someone's game can I disect it in VS? :0 I tried going to open project, then I went to the folder and clicked open. It brought me inside of the folder so I tried to open the game but there is no form1 there. It says the games name then .exe in the explorer-like thing in the top right?Also, how would I have a value or something in a label and access it from a button.
Example:This is in a label.
Dim number as Integer
number = 0
Then in the button do
Label.number = 0
How would I do something like that? I want to use that a lot as I did in a different language.

View 1 RepliesBox - Conversion Error - User Enters 6 Numbers In 6 Different Text Boxes - Displays The Larger Of Those 6 Numbers
Oct 4, 2011I am making a program, where the user enters 6 numbers in 6 different text boxes, and it displays the larger of those 6 numbers. But I also want to make it where if the user enters a string value (like S for instance) in the text boxes, it gives an message and says "please enter the numbers again" and the user gets to enter the 6 numbers again. But when I do try to do that, it gives an error message saying conversion from "w/e the user entered" to Double is not valid. If the user just enters the numbers, it works fine. However, I am trying to make it if the user does enter non numeric value, it gives a message window and the user can reenter the numbers again.
Here is my code Example
CODE:
This is where I am trying to use IsNumeric to show a message if a user does not enter a string so the user can renter the numbers again, but when the user does enter a string value (say in textbox 1) it gives me an error message saying conversion from "S" to 'double' is not valid.
CODE:
Then right here this is where I have my series of ifs statements, this part works fine, it displays the largest numbers of the 6 textboxes every time. Error free.
CODE:
And do this with variable number 2, 3, 4, 5.
I know there are easier ways to do these with arrays and stuff. But I am not there yet. I am still learning about ifs and stuff.
Program To Randomly Select Numbers For A Bingo Caller - Prevent Reversed Numbers Being Selected
Mar 6, 2011I have just about completed a .NET project to write a program to randomly select numbers for a Bingo caller. Over the last month or so Ive learned a lot about .NET but heres something that I consider to be odd and maybe one of you guys can offer an opinion.
One of the features of calling Bingo in a small local club is that callers often use little sayings to accompany certain numbers, I expect youve all heard of (say) All the sixes, clickety click for 66 or 5 and 9 the Brighton line for 59 etc. My little program gives an option to incorporate these with a prompt for the caller that can be edited outside of the program. One of these conventional sayings is used when a number is reversed 12 followed by 21 or 45 followed by 54 for example, when the caller might call (say) 1 and 2, one dozen, number 12 And the other way round 2 and 1, twenty one.
So, I programmed in a bit of code to detect this and to over-ride whatever might otherwise have been the quote with And the other way round and set about testing it. Ive been through literally dozens of full 90 calls watching for the occurrence of a reversed number, spent a few hours doing it, and not once has it occurred which is to say the least, unusual.
So, Im wondering about the Rand Function, could it be that it isnt possible for a reversed number to be selected? Just so you know, I randomly pre-select the order of all 90 numbers, I fill each of the 90 elements of an array with a random number first checking that the number selected hasnt already been stored, if it has, I just get the next random number (and check that too of course), but I cant see how that could prevent reversed numbers being selected, especially in light of the fact that frequently it's not the 'next' number that's used.
