I would like to develop a very simple question-answer program whereby there is a user form with a label which contains the question, a text box where the user enters the answer and a button that the user clicks to change to the next question. This should be rather simple but I would like to have about 500 questions in the end (will be slowly adding more questions).

View 9 RepliesI recently made a simple pseudo-encryption program that changes each character into another. It is capable of encrypting and decrypting a string. This can also be done to any text file as well. The characters range from ASCII 32-254 (This on it's own may be an issue because of #127 being DEL).
Because I believed my own coding may be at fault, I attempted this with Triple Des with identical results.For Triple Des, the requirements for en/decryption was:
Encrypt: String to Byte
Decrypt: Byte to String
And to change them either direction, I used UTF8. I also attempted ASCII and UTF32, but I don't know what I should do. I am considering dropping this but I want to learn problems like this because I am currently in college and haven't started my core classes for programming yet and want the head start.
The point where I have come into a problem is attempting to do this to another file type like an image. I looked at the results from encrypting then decrypting and the results were similar, but it seems file encoding must be the culprit.
Im learning Visual Basic 2010 on my programming class and we reached the part of file handling. Here i tried to make a simple program that can create a text file with the content of what i type on the textbox, basically i create the file if it doesn't exist, and if it already exists i append the content to it. Once the file is saved i can read it using the "Open" button. Unfortunataly, whenever i try to create the file, the compiler gives me an error saying that it cannot modify a closed file, although i've followed up the execution instruction by instruction and i can't find the error.

Im trying to create a program with a simple gui that enables me to search for and select parent folders containing child folders containing multiple files and then validate those files based off of constants i set per child folder and file.
Example
User selects Parent FolderX
Parent FolderX > (ChildFolder1 ( Constant for ChildFolder1 says open file 4 ) > File 4
Compare multiple strings of text in a specific order based off of file name to constants i have set for that named file Then continue to ChildFolder2 ( Constant for ChildFolder2 says open file 16 ) > File 16 Compare multiple strings of text in a specific order based off of file name to constants i have set for that named file If there is any constants not read in one of the files after all have been checked, return msgbox with a notification and write .txt log with child folder and file names to specified directory?

View 4 RepliesI want to distribute a fairly simple program developed on Visual Studio 2008. I have tried to use the publish features in the IDE. It creates a folder with various information and stores it on my fileserver.When I try to install the program on another computer I get a lengthy message about the need to install Powerpack 9. 0.0.0 So I go back to my dev computer and edit the publish information.

I said in a thread this week that I would set out to construct a program using the WMP component and this time, unlike in my last one, it is set up to allow any folder to be chosen. It's safe, even if the user chooses a folder with no .mp3 files in it, but it's goal is to look through all folders/subfolders, find the .mp3 files, get the path and the meta information about it, then show it in a listview.
The user has a few options such as playing the first song when a list is loaded, setting it to shuffle, etc., and all settings are saved automatically. Also, when they choose a folder to use to get their music, the next time around it remembers this also (although this latter one is done by saving the path to a text file so that you can, optionally, edit that before you send it out -- without having to change the code to do it).
I have it looking at events so that no matter what they change (click for the next song, change the volume, change one of the checkboxes, etc.), it will re-focus the listview so that the song presently playing is highlighted.[code]...

I'm a unviversity student and for an assignment we have to make a simple project where the user specifies a shape and a color, and then the shape is drawn in some kind of space. So like they choose circle, green, and in this blank space on the form a green circle appears, pretty simple. Anyways we have some kind of msdn alliance thing where we can download Visual Studio for academic purposes, so I downloaded Visual Studio 2008. I spent about an hour going through the tool box trying to figure out what could possibly allow me to draw stuff in it, and I'm really not sure what it could be. On some online tutorials it said something about a function on picture boxes like picturebox.Circle(100,100), 100, vbgreen or something similar, and when I tried making a picturebox and writing this code nothing worked. My friend told me to use a 'canvas' but neither of use know how to actually find such a control (its not in the toolbox).[urls]....
