I would like to be able to search any record that is mark with a checkbox to show up in my search screen when I do a search: [code] The problem that i am having is that now that I have added the code to my project to search for the checkbox field in the search screen and if I leave everything blank and click on the the search button I get no record found. I expected to see all that data, since I have nothing selected. Now if I click my checkbox, as soon as I click on my search button I see that two records that I have added for my test.

For example:

' rValue now has the XML string <indracio fire height=23, width - 6>
/* This is the string that I want to search. Replace the words "indracio fire" with the word "lucion time"

I have a 133 Mb file which contains almost a million records. Currently, a user loads this file into KEdit (a great editor for working with large files) and changes occurrences of a dollar sign $ to blank and takes negative numbers represented as such with parentheses and changes that to a negative sign. That is, (5000.23) would become -5000.23. So the leading ( becomes a - and the trailing ) becomes a blank. I believe the only occurrences of ( and ) are around the numbers I want to change, so I don't have to worry about changing something that should have been left alone. Using VB.NET in Visual Studio 2008, is there a "painless" way to do this other than reading the file one record at a time and searching/replacing and writing the record out? While not really painful, I am worried about how long that will take (to run, not to code ). Is that a valid concern?
My long range goal is to automate many of the routine file preparation tasks my users do. We get an input file from 15 clients. The file can be in any format the client has chosen to give us, and it is our burden to reformat any errant fields into an acceptable format for insertion into our database.
I've figured out a way to load a php file and then search and replace if it contains one of the following:[code]Is their a way where I can load the the php file and also load a txt which contains the string i want to replace, so the exe dont actually save the txt.Replace. This way the user of the app can define the contents of the search and replace and it wont run out of memory.
View 1 RepliesI got some code that im try to make search and text file and replace it. The code im using to replace it with is whatever the user entered in txtURL.text. Here is what i have
Dim strFile as String
Dim result as String
strFile = "C:\test.txt"
oRead = IO.File.OpenText(strFile)
result = Replace(oRead.ReadToEnd(), txtURL.text, "1F.php")
oRead.Close()
Is this writing it back to the file also....I think that might be the problem, not sure..
I am writing a program and I have the Read Function all written out. I need to have the write function. I think is I copied and pasted from the Read function I wrote.
I was able to Mass edit This:
Reader.Position = (&H)
NumericUpDown281.Value = Reader.ReadInt16()
Reader.Position = (&H)
NumericUpDown280.Value = Reader.ReadInt16()
Reader.Position = (&H)
[Code] .....
And there is at least 370 NumericUpDown's. Is there any way to search/find/replace all in one instead of typing:
Find what: NumericUpDown320.Value = writer.WriteInt16()
Replace with: writer.WriteInt16(NumericUpDown320.Value)
Each individually?
The write function will only write properly this way:
writer.Position = (&H)
writer.WriteInt16(NumericUpDown66.Value)
And not this way:
writer.Position = (&H)
NumericUpDown319.Value = writer.WriteInt16()
Is there a way to look in a textbox for some text1 and then if its there, it is replaced by text2?

I'm a bit of a noob at this and finding that all my research that's led me to wanting to do things right for data integrity are making it a bit more complicated on the front end.
Presently I have a Form in which I have two DataGridViews that I'm populating, each with it's respective stored procedure.
What the form is for is for linking rows from the one DataGridView (I'll call it DGV1) to a different one in the other DataGridView (DGV2).
Now to facilitate the ease of doing this for the user I want to both have the dgvs fully populated so that if the user wants they can just slide on through and manually select the rows in each they want and then there'll be a button to select which I'm planning to then use another stored procedure to then insert this connection between these two items into the database.
Another thing to facilitate this is a search bar. I want them to be able to type in something and have the datagridviews both navigate to where their selection is as well as selecting it so that it's then ready to be bound to the selection in the other.
What I'm wanting to know, and having a hard time figuring out, is how do you get such a search function to work on DataGridViews that I have bound to these read only stored procedures? How do I search and select within the DataGridView? And then how would I go about using the selection from two different datagridviews and putting those as parameters in the stored procedure that I wanted to use to then record the relationship in the database?

If not found it should give a msg.'Both the tables are linked on CustomerID.
