Search & Replace

[Sensimillia]

What I want to do is this. The user will specify the file. The program will specify what to search for and the user will specify what to replace it with.

Is there any way that I could access the windows api to use the search & replace feature with an open file?

well, if u want to replace a string in a text file, why don't you open the text file and read line by line. then you can search the string you want in that line and replace it with the string you want to replace. after that close the text file...

1) Open TextFilePath For Input As #1
2) While EOF(1)=FALSE
Line Input #1, data
Replace(expression, find, replacewith[, start[, count[, compare]]])
wend
3) Close #1

Get what I mean?

Thats my problem. How would I just replace 1 line without loading the whole text file change the line and then saving the new text file.

Is Replce and actual command.

Is there an overwrite command that can find a specific line.

If possible I really think that Search & Replce API would be best.

And Remeber this a really large file so the whole thing might not fit sufficantly into variables all at the same time.

Ok well it looks like replace is an actually command. Thankz.

Can you give me a link to more info on this particualr command?

for some reason the search bar does not work on my comp :0(

Replace is a real function in VB. The syntax as I written there :
******************************************************************************
Replace(expression, find, replacewith[, start[, count[, compare]]])
The parameters are as below :-
1. expression - Required.String expression containing substring to replace.
2. find -Required. Substring being searched for.
3. replacewith -Required. Replacement substring.
4. start -Optional. Position within expression where substring search is to begin. If omitted, 1 is assumed.
5. count -Optional. Number of substring substitutions to perform. If omitted, the default value is –1, which means make all possible substitutions.
6. compare -Optional. Numeric value indicating the kind of comparison to use when evaluating substrings. See Settings -section for values.
*****************************************************************************
1) Open TextFilePath For Input As #1 'this really open a text file (replace the TextFilePath with actual path)
2) While EOF(1)=FALSE
Line Input #1, data 'this will retrieves data line by line from the text file as long as the file in not EOF
Replace(expression, find, replacewith[, start[, count[, compare]]]) 'do the replacing here
'save it and do whatever processing you need
wend
3) Close #1 'this will close the text file after you use it.

What actually do you want to do with a ChooseColor API and FindReplace structure?
The ChooseColor function creates a Color common dialog box that enables the user to select a color.
FindReplace is simply a types and I can't see any connection between those two.
