View 4 RepliesI was hoping someone could assist with the following coding; I am trying to search a very large csv file (approx 200,000 lines) for a user defined string eg "0100020789" and I essentially want to print all the lines that contain this to a text box on screen. Please not that the csv file does not have standardised column headings, each line is different. There would be approx 5 lines that contain the input string.
I am concerned with the v large csv i am using which will prob slow everything down, but then I thought if simple text pad application can search for a string in complete files with similar sizes like that and return a result in less than 1second, then it must be do-able.

View 1 RepliesI have the following problem where in VS2005 VB I am returning all text in a text file to a rich textbox for preview purposes. Once I have returned this I am searching for a specific word (sv_hostname) and I need it to return a different result (Server name Here)on the same line to a text box. For example: Test file contains lots of lines where one of the lines would look like this within the text file.
set sv_hostname �Server Name Here�
I want textbox1 to only show Server Name Here The user must then be able to modify this and append this to the text file/rich textbox.
My Code so far:
vb.net
Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click
Dim ServerName As String

Base class has one field to hold numeric balance value. With 2 methods that accept arguments for adding and subtracting the new input calculating new balance. Sub class has four fields dates, transaction, memo and amount.I have a deposit form, and withdraw form. Each time one transaction is entered it creates an object with sub class fields, then adds to the account collection. My problem is not understanding how to call the deposit/withdraw method and pass the current transaction amount back to the base class to alculate the new balance. Does anyone have any links to information/tutorials on how to perform something like this? As you can see with my code I have tried various different approaches without any success.

I'm using ASMX web services in VB.Net in VS 2005. I am calling a function method on the web service that returns a true or false value. This works fine if I call the the web method synchronously, but if I want to call the method asynchronously, the function returns to a sub and there is no return value; therefore, I can't tell whether the result of call is true or false. Is there a way to make an asynchronous call and still get the true or false result (perhaps using the userState Object)?
For Example:
Dim MyResult as Boolean = MyService.GetResult(10)
Dim MyResult as Boolean = MyServer.GetResultAsync(10)
This doesn't work the compiler complains: "Expression Does Not Produce a Value"
I have a directory that I need to search. The search will look for all files inside that directory and all the subdirectories. The filenames will output on a listbox. The problem is when I run the search, it returns all the filenames plus the full path.[URL]..I only want to show the filename and if possible, the file creation date.
Listbox output should be:

Filename3.xls File created on 2007-10-17

View 1 RepliesI have sucessfully written in excel VBA. The idea is to used the textbox1_change event to find a match in column A of table and once it finds the record, return the value of column B as label1.text. [code] In VB 2008 it's a lot different. I have set up the form the same way with the textbox and labels. I have made a dataset with (1) table (Table1) with (2) columns. Lets call them column A and Column B.I have added the dataset as a binding source to the form and also a table adapter. I also have a standardized query made for the dataset with a very simple SQL statement "SELECT Column A, Column B from Table1"..In order to get the user input to start searching Column A I assume under the textbox_change event i would put something like: [code] I'm getting a bunch of errors of course. Would somepne be able to give me some direction?
View 3 RepliesUsing VB 2008 with Access database I'm trying to make a search field (txtSearch), but I'm not getting success with code in the button (cmdSearch). I'm making this manually, not using the Query Builder, and the result will be displayed in a datagridview (added to the form dragging the table from the Datasource Panel). So, the datagrid is already populated (with no SQL). What code must I use for the cmdSearch, to return the txtSearch.Text (or part of it) in the Datagridview? I've tried this: "Select Product, Price, Quantity FROM tblProducts WHERE Product LIKE txtSearch.Text & '*'" (but it doesn't work).
