I just finished putting the first 6 datagrid controls on my form and i went to go test it and got this build error: Error 4 Value of type 'String' cannot be converted to 'System. Windows.Forms.DataGridViewTextBoxColumn'.C:SoftwareForm1.vb 1425 19..When the line generating the error is this Me.Name = "Form1".where it has the "Form1" portion underlined in blue.This is a weird error because that line was made by the IDE to say the name of the form and has nothing to do with 'System.Windows.Forms.DataGridViewTextBoxColumn'.I tried saving my progress and restarting the IDE with no luck..Now I cannot even access the form in designer mode,One or more errors encountered while loading the designer. The errors are listed below. Some errors can be fixed by rebuilding your project, while others may require code changes.The designer cannot process the code at line 1424: Me.Name = "Form1" The code within the method 'InitializeComponent' is generated by the designer and should not be manually modified.
View 5 Repliesi made a program in which you put in a number like 10, and there are 10 cards. If you put in a number like 23, here is a possible output -
Card #1 - 3
Card #2 - 20
the rest 0
etc, where all the cards values adds up to the number you submit (the values displayed will be random)
The thing is, when i do a number below 10,000, it will come up as one card equaling that number and the rest equaling zero. If i do it a number 10,000 or larger, it will split it like it is supposed to.

interestingly, if you put in a break point, it works like it is supposed to!
What is going on? And why does it matter the size of the number for it to matter?
When i get home i'll edit this with screenshots.
When i was making my program, i went to import Shockwave Flash Object and AxMedia Player, But they were not there. I know a way of restoring them, Dll's but, however i cannot find the DLL in the folder. Can someone either give me the location in an example "/vbexpress/*****" Or can someone give me a download link to the DLL so i can do that, aswell? I think the download link would be the best.

It's all gone quiet since Edit 19ish and @Chris reinforcing the issue with a good example (thank you Chris). I'll make the question a little easier (and attempt to tidy up all of the above), can anyone prove this is not an MS bug or similar? It seems to be something under the hood is not correctly wired up for VB.Net with regards to Nullable Structures and Events? However, all other cases using the Nullable Structures does appear to work?
I'm trying to add a string to a listbox if there is none exact string existed inside, but it turns out a very weird error. Look at this.
On form_load, I have this:
AddHandler Server1.OnUserLoggedIn, AddressOf HandleUser
And then,
Public Sub HandleUser(ByVal username As String)
'Here, you handle adding the text to a text box.
Me.Invoke(New PrintMessageDelegate(AddressOf AddUser), username)
End Sub
[Code] .....
The output is when I connect the first client, it works fine. But, when I try to connect the second client, it prints out three times both the listbox1 item and the txtDisplay. It's like get caught in loop, but I have tried other kind of loops like for each and other string comparison too, still work that way.

I have code that adds 0.25 to textboxes each time + is pressed, and subtracts it when - is pressed. This is the
[Code]...
I don't know of any better way to have it handle each textbox, hence the long string.Anyway, these boxes are populated from a database and this code seems to work fine if there is already a number in the box. If the box is empty and I try incrementing it, I only get the actual "+" or "-" in the box and it locks my whole form out. Clicking other textboxes doesn't activate them, and my buttons press but do nothing. I can't even exit the program with the "X" in the upper right. As far as I can tell that's how to replicate it anyway.
I am capturing a few system command messages (namely minimize/maximize/restore). Inside the WndProc override I am trying to change the form's Me.ShowInTaskbar value but it is causing weird behavior in that minimization and restoration does not occur properly.Can anyone think of a reason why changing this property would interfere with this? The reason I don't really want to post code is because duplicating the effect takes a bit of code/setup. My initial thought was that changing the property's value is somehow sending another windows message and canceling the one I am currently manipulating. I realize this is a little vague but it's a shot in the dark.
View 1 RepliesI have in a menu a ToolStripTextBox where the user can enter a CASE NUMBER to FIND. And I have a ToolStripMenuItem below that says QUICK FIND - clicking this will find the case you put in the textbox. Tabbing out of the textbox puts you at this TOOLSTRIPMENUITEM so that ENTER on the keyboard will trigger the FIND. I want to make it so that pressing ENTER while still in the textbox will trigger that same TOOLSTRIPMENUITEM action. Do I have to trap keypresses or is there a more natural way to accomplish this?

I set the visibility in each leaf element as per the permission given in DB. But I want to set visibility=false in case all the leaf elements are set to false.

I'm trying to add functionality to my application to let user define "custom actions" in one of the context menus.Essentially, these would be command lines that can be executed against remote machines.I've got the code to add the menu items working but I'm not sure of the best of storing the data related to the menu items. At the moment I'm using a Specialized.StringCollection in the project settings but this only allows me to store a single line (i.e. the command line).This means that the text of the menu items is whatever command line the user has defined (not ideal).What I would like is to have a "friendly" name for the menu item (e.g. Start Notepad) and have that associated to notepad.exe.What's a good way to store this data so that I best dynamically build the menu items every time?

View 3 RepliesI want to create a regex to find words which have capital words in between them. Can anyone please tell me how to find it?For example: I went to a school forEducation and then didn't study.I want words like forEducation. I think we use [a-z][A-Z] to find all alphabets but can't really find it. I am thinking along the lines of merging the above two options, but then how is it going to check for capital alphabets? Also I wouldn't want to select any words which have capital letters in the start, because they are valid.Reason : This is occurring because of scraping text from online websites and they have no proper formatting. I get these words as text and want to replace them.

View 23 RepliesI am adding characters to a RichTextBox one character at a time and setting the format of that character after it is added. The following code is a distillation of the actual code but reliably repeats the problem I am having.[code..]
While that is odd to me and unexpected, where it happens in the code is even stranger. By stepping through the code, prematurely going to the End Sub and then displaying the form, I was able to determine that when i = 3 and the line "Me.RichTextBox1.Text
= Me.RichTextBox1.Text & "S" is exceuted, the color of the first two "S" are changed from Blue and Red to all BLUE.
I do not understand.a way to add characters to a RichtextBox and set the formatting of those characters?
This example is just color. I the real project I am setting Size, Color, Bold and Italics. I do not know if the solution to this color problem will affect the other formatting information.[code...]
