I need to check the current date and month to see if they are only 1 character long (1 - 9 - January to September) and if so I need to insert a 0 before the value in a string.Now the code I have been using is Len(Now.Month) which for some reason is returning 4 even though the current Month is February (thought this would return 1).I I use Len(Now.Month.ToString) it comes through as 1, which is what I want.

[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.

View 3 RepliesI 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 2 RepliesI was getting weird results when doing multiple splits on a string, so I decided to make a simple test to figure out what was going ontestString "1234567891011121314151617181920"If I wanted to get whats between 10 to 20 in Javascript I would do this:var results = testString.split("10")[1].split("20")[0]Which would return 111213141516171819However when I do this in VB I get 111Split(testString,"10")(1).Split("20")(0)It seems the 2nd split is only recognizing the first character no matter what I put.
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 6 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?

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...]
When i was making my program, i went to import Shockwave Flash Object and AxMedia Player, But they were not there.

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.

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.

View 5 RepliesI 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.

This is all done through the website, but when I search for ProductID 331 and click on it, it goes to the error page that says Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
It doesn't make any sense to me that the website would error with only this one product. This is the statement I am using. Does anyone know why 1 product would be causing this error?
