this is my first post in this forum! I guess my question is very simple. I just started with VB.net yesterday I want to search through a text string, and then count how many times a word appears. How do i do this? Is there some sort of function that i can use together with a loop of a kind?Something like the inStr(), just something i can use with mulitble appearences!
View 4 RepliesThe length of the previous words is exactly the same but the "truth length" it is not. I want to know if there is any way to find the truth length of a text string with different fonts The reason why I want the "truth length" is I want to make an rss scroll bar and when the first label "hiding all" in the right to send the next rss it in the left.
View 2 RepliesI have to find a string in a huge text file ( ~ 50MB) and then replace it.Since it's quite huge I tend to open the file and then read line by line, and then replace the necessary line(s) (rather than "readall" the file of course).My question is how to replace the whole line?Let's say I found the line that should be replaced . I know I can create a copy file and copy all lines into there ... but I'd prefer to replace the line in the original file rather than creating a copy instance.
View 5 RepliesI would like to step through each *.txt file in a given directory, open it, find and replace all, perhaps a thousand, occurances of a given string (e.g. "00/00/00"), then close and save file, and step to next one in the directory to do the same find and replace. I've been looking at filestream classes and regular expressions but don't see a clear way to do this.

I'm looking for how to set the error markers (red ! marks) in a Windows.Forms.Datagrid. After research I believe they appear after some validation routine, but how do I set these manually? E.g. If each row goes to a stored procedure I'd like to place an error marker whenever the SP returns an error

I have thios code that will load a php file (text file) into a sting via streamreader then its supposed to find and replace a portion of the text and write the changes back out to the file via streamwriter. I put my code together and after running it look at the file and it's unchanged. After looking closer it appears the problem is the find & replace operation I am doing on the string. Here is my code:

I have a wrapper class created around TextBox, and I want to find out if there is any way to test if the vertical scroll bar is at the beginning (the very top) of the text box and at the very end of the text box.Alternatively, I will be happy if only I can find out a way to check if a scroll bar is enabled or not in a textbox (note: it's not a RichTextbox).
By enabled, I mean that scroll bar is actually enabled i.e. you can use the scroll bar to scroll the control, not just visible (I know we can check visibility by GetWindowLong)
I'm adding a method to find and select text in my text editor. Everything worked fine, including the ability to find all instances of the text. My problem came when I tried to make it more user-friendly (doesn't it always?). Originally I had only a menu item with a shortcut( Ctrl + F) which invoked an input box.
Then I added a textbox and a button (similar to that seen in a web browser's Find() method) that calls the method in the same manner as the Find/Replace menu option and displays the desired text in the textbox. Everything works fine except that the text is not selected. I have MessageBoxes displaying the values of required variables in 3 places (marked ***FOR DEBUG ONLY***) to make sure that no values are being changed, but all variables are the same. The method still locates the text, but it is not highlighted.
I think it could have something to do with which object has focus. (When I click the button, the selected text loses focus?). But if I click everything with the menu items, it still works...

I have a little question about txt-files...This is the case: I am going to make a small software for editing particular parts in text files, so you don't have to do it by hand. In this program, i need to find several words in a text file and retrieve the text or number that is after the the "="-sign, and then replace that info. Then, I want to use the information it retrieves to add some text in the end of the file.
P.S. There are 36 differet words to search for, and some of them will occur in several places, so i want the data from those words that occur several times in an array. And the data i want to retrieve is AFTER the searchword and a "=", so i dont want the searchword or the equals-sign included. Can someone explain to me how to do this?
