View 2 RepliesIs it possible to declare a variable using the text of, lets say a string, as the name?If u dont get it im looking for something like;Dim Var + string1 As PictureBox..In the code "Var" is the start of the name and "string1" is the end of it so if string1 was "Hello", the picturebox would have been named VarHello.

How to improve my code. Im the worst ever at OOP programming. The main reason is i dont understand how i can pass variables between subs/functions e.t.c. I've read up on overloading operators but i dont feel that i can grasp it. If someone has any comments or any simple examples on improving my ability i wouldnt mind hearing them ^^
This is what i have now. Attached project (with "graphics") without .exe files and all code is also below. Also an image of what it looks like below.

I'm trying to export a listbox (lets call it Listbox1) to excel 2007 and I'm having some trouble with it.

Need to get code to read all cells from row2 from excel worksheet1 and move into 2 dimensional array (rownum, colnum). I looked at forum for hours and its SOOO more complex that I need that I'm sure my confidence as a vbs person thinking this .net vba is simple
View 3 RepliesI have a little issue. I need to be able to concatonate the Row1 with Row2 to another/row/table, and the start again on the 3rd row, Join Row3 on Row4 .. and so forth. The issue i have is that there is no relationship between Row1 and Row2. The only common thing is that Row2 is part of Row1. Can this be done? (Can be done with either by SQL SERVER, SSIS or ASP.NET VB) Below is a sample output of the data in column1 (single column)

I got a textbox with lets say 3 rows of text
1.Hello
2.My name is
3.Simon
And i got a listview that is on detailed...When i press a button: for each row listview item add.So the listview items will be 3 items, 1 item per row in the textbox thats on multiline.
Basically I need to make a program that lets a user browse and choose a folder, then I need a box that the user can then select the files to work with, then with the selected files I need to put them into a zip file. I'm trying to use a list view box but having all kinds of problems using the data in it.
View 2 RepliesI am currently converting a 90s VB6 application to VB.NET. While testing I came across something curious.A Modal form by definition will prevent users accessing any other form in the application.This I discovered is not always true as I have a Modal form displayed which allowed me to access its owner form's Menu.Searching MSDN I could find no mention of this feature. So I thought I would share it:Click Button 1 on Form2 and Form1 comes back to life!
View 12 RepliesI am facing a rather odd problem right now. If you fellow this : Best place to put key or password used for encryption? i was looking at a way to encrypt data. Using RSA seemed to be a good choice. However we have a problem since my requirements are thoses fellowing...Client must have a file encrypted in order to determine if the software is activated.
That actually mean that the client must read the encrypted file.. but the problem is that we actually need the private key to be there which isnt a good idea since some poeple could start making their license file using that key. The activation server encrypt the data file which are sent back to the client and then the client save that file.
Client must have a file encrypted in order to determine if the software is activated.Client sent user data to the activation server in unencrypted/encrypted form. That doesnt matter. Sure it would be better encrypted at this point.The activation server check that data and then determine if the client can be activated.If the client can be activated then the server send the encrypted form of the license file.. but the problem appear now.. there is no way to deencrypt the file on the client if the private key isnt on the client which would be pretty insecure!
I'm trying to make a hash calculator (For testing now)
I know that MD5 is a 1 way(Meaning that there is no decryption for it, yet)
now I was wondering if SHA-1 is a two way. Also, is there any other hashing method that are 2way?
reason is that I want to convert a long string (Lets say 550 chars) into something lower (From 550chars to something lower then 550chars)
I can use a Key, but every possibility will give me bigger length then the actual string.

counter = 0
Do until counter = 10

I have the following linq statement to go through a dropdown menu's sub items and get what items are checked: vb Dim UnselectedItems = From xItem As ToolStripMenuItem In tsiSelectObjects.DropDownItems Where TypeOf xItem Is ToolStripMenuItem AndAlso CType(xItem, ToolStripMenuItem).Checked = False
I get this error tho: Unable to cast object of type 'System.Windows.Forms.ToolStripSeparator' to type 'System.Windows.Forms.ToolStripMenuItem'. As you can probably guess i have ToolStripMenuItems and separators in there
However the AndAlso should short circuit in the case where the item is not a ToolStripMenuItem and it doesn't seem to be doing so (as TypeOf xItem Is ToolStripMenuItem=false in this case)?
i have a listview box full of items, image below:

I have to create an application that lets a user enter as much grades he wants. The grades are between 0 and 100 and they can't be negative. Whenever the user type -1, the application is done and it shows the average of the grades, the lowest and the highest grades.I absolutly have no idea where to start but i must be using loop/do/while.
View 4 RepliesI have a little situation and i am not sure of the best way to do it.
- My program lets the user select a folder
- From that folder i need to select all .png files
- One by one i need to load them into a picture box, await a button press and then go to the next image.
The above that i have typed in red is where im not sure what to do. The other steps i can do.
I know how to do what is in the subject already, but I want to do it a different way than what is stated in the subject. What I want to do is be able to create multiple items with different names and then load the names into a listbox. When I select the item in the listbox with the name, such as Item1, it will put the text from the control named Item1 into a textbox.
I am clueless as to how I could accomplish this. What I am doing is adding Items to a menustrip's dropdown Item, then adding items to the dropdown items. So I would have the item collection such as:
One
Two
Three
So I could choose the item in the listbox with the text "Three" and I could load several properties of the item Three. Such as Three.text, Three.Tag, and Three.Name. And I could also edit these. And then when Three is chosen in the listbox, I could add sub items to it.
So it would look like this in my perspective(Although the code would not work)
Dim tsmBookmarks_SubItem As New ToolStripMenuItem
(Listbox1.selecteditem).DropDownItems.Add(tsmBookmarks_SubItem)

I'm trying to make a program that lets you type "A" in a text box then it plays an audio file.
My code is: If MaskedTextBox1.Text = ("A") Then
i am making a game in which the file stream gets a certain file(lets say a.txt) and it reads it, if it has certain values stored in the file it returns boolean(this is a function), then a sub procedure writes to the file using a streamwriter and a filestream using the same file. I am having problems, sometimes visual basic says that another process is using the file, this is before i closed the filestreams and the streamwriter or streamreader, then it gives me errors when i close the files, it tells me that it can't access a file that is already closed, i thought the filestream gets the file and lets the streamreader or streamwriter read or write to the filefound out the problem?
