Trying to create a program that accepts a square array size 4 by 4. Then it should print the totals of the rows and columns. I started with a form and made text boxes and created a print button. I made it so that numbers can be input into the boxes. When hitting the print button, it should print the totals of what was input, however, it isn't doing that. Is there a different way to write the array code so that it will print it? Should i not have text boxes but rather have labels with fixed numbers set in them?

View 18 RepliesThis was an experiment to see if I could create a fake array using generics instead of using an array. I decided to try it, because I may use it if I find any advantages to using it over an array. it works, I am just asking for a second or third opinion, have I screwed anything up, or is there an easier way to accomplish this? If I use it, it will be for a 2D game I am creating, and is used to draw the 2D screen graphics, placing an image based on what image identifier is located at what coordinates. The value stored in the fake array is an integer that disignates the graphic to draw and whether it is passible or not, i.e. 0 = a floor image, 501 = a wall image that is impassible (any image number > 500 is impassable) The Class definition:

View 2 RepliesI have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?

View 20 RepliesI am very very new to VB.NET and would like to ask a simple question. I want to create a vb.net program and allow visitors to a website to download this program. However, I prefer not to have visitors download a zip folder. I would like to have a program that just gives a prompt to save in a selected folder, once the saved file is selected it prompts the person to download, and then when finished prompts the person to run the program. The reason is twofold:
1. I don't like the extra step involved with unzipping the file. and 2. I don't like the visitors having to look for the "main" file program within the new downloaded folder. So is there any way to have just one file for others to download without having it in a zip folder?
I want to create an array of an array (or arraylist of an arraylist) to hold strings.I want to fill an array1 with string values Then add this array to array2. - but only taking up 1 row in array2 e.g something like array2(index)=array1 Then clear array1 then loop through this again with different data, and add it to the array2.so will end up with something like
array2(0)... contains a collection of array1 data
array2(1)... contains a collection of different array1 data
.. and so on
i think i need to make new instances of array1 each loop, but not sure.I dont mind if it uses arrays, or arraylists, or lists, or structure of arrayslists?
I'm trying to create a program that installs required .dll's for a program due to a clean install..What I need to do is Get a value in the registry and use it for the program files path.. but I've noticed some pc's don't have the same configuration because of the version the user is using. Anyway This is what I have so far:[code].....
What I'm trying to do is find a registry key called "SoftInstallPath", if found I need the end of the path to goto the new directory(new_dll) not the old one (dll).. and if "SoftInstallPath" cannot be found.. I need it to find "ProgInstallPath" and use it instead and do the same thing.By the way I'm using Visual Studio Professional 2008 on a Vista x86 machine.Also error I keep getting is: Warning 10 Function 'FixPath' doesn't return a value on all code paths. A null reference exception could occur at run time when the result is used.
