in the keydown event of a textbox (textbox1) as text is typed in i want it to "knock off" items that dose not include the text in either colum 1 or colum 3.How can i do this ?
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles richTextBox1.TextChanged
'code goes here
End Sub
How can I remove items if the listview colum 2 contains a certain word?
example
Col 1 Col 2
John Hired
Joe Fired
Bob Fired
after clicking a button it would remove the all the Fired items so both the person and the fired would be removed.
In the following code, a selection in excel is selected. All of this information is then transfered to The DestFile. In this case the DestFile is Firm_ATC0.asc. I would like the program to put all the information from the A colum in the Firm_ATC0.asc file, and all the information in the B column in the Firm_ATC1.asc file and all the C column to go in the Firm_ATC2.asc file ect.Basically every time the column increments by 1 the Filename it is going to increments by 1.There are A to CV Columns selected in this example, and I think that is 99 columns and therfore there are Firm_ATC0.asc-Firm_ATC99.asc. Currently the information only goes into the one file.

A program that would usually take me a few hours to make i am on day 5, 4 and a half of which have been trying different ways to get it to update, and not one of them will post the information back to the SQL 2000 database I am actually going insaine.
The best i can get out of it is this error.

My data comes back with 4 places on the end

I don't believe there will ever be a point where the last two are anything other than zeros.

I'm trying to include a few text files in my project. These files are read and used to make decisions in the program. Ordinarily, I would just set the file path and open the file via StreamReader, no problem. However, this application now needs to work on other computers and I want to include the text files in the application directory. I've researched two ways to do this:
1) Include the files as resources and reference them via my.resources.
I've gotten this to work ok, except the files are opened as strings upon starting the application. They are fairly large files, which I imagine is taking a lot of unnecessary memory. Also, StreamReader wont work with these files as resources,
or at least I can't figure out how to. My application is already based around using StreamReader so I don't really want to change this.
2) Include the files as additional items. I know how to do this too, but I can't reference the files programmatically.
Can I use a resource text file via StreamReader or how would I reference the files if they're included in my project directory?

I'm using IO.File.ReadAllLines(FileName) to read all lines from text file to array of strings at once. Problem is, text lines include ANSI characters above ASCII value 127 (Scandinavian letters e.g. "Ä" (Ascii 196), "ö" (Ascii 246) and "é" (Ascii 233). Array is build up nicely, but all chars above ascii value 127 are not shown right. How can I use ANSI character set with .ReadAllLines to correct this problem? In VB6 with "Open Filename For Input As #1 / Line Input #1, txtLine" there wasn't any problem.
View 1 RepliesWhen I publish my program I get no errors, and then when I install it on another machine it says it gives me the error that it can't read the txt file that it stores data in. If I hit continue it also fails to read the database. The database file is stored in the bin/debug folder and I told my program to include it when I first added the data connection. Anything I can do to have these included so my program can run on other machines?
View 6 RepliesFor a class project I am thinking of doing a Spelling Bee game. I would like to have a button that will place the word in a sentence, and a button that will give the definition. Are there .txt dictionaries out there with this information? I've checked a few places like WordNet but I didn't see a dictionary that also includes sentence info. My other concern is using custom classes. I don't have a lot of experience creating classes, and I really want to become more familiar with them, so it is important that I integrate them into this project. What would be a logical way using classes in this project? Maybe a 'word' class?
