View 1 RepliesDB/Reporting :: DataViewGrid Enter Key For Windows
Aug 16, 2009I am using VS2008 using VB. I have a datagridview sourced to a dataset. There are 5 fields mapped to the datagridview, three are read only. I am using the 'RowLeave' event to do some processing.
I am using the 'CellEnter' event to 'SendKeys" a tab in the read only cells. The question is simple: how do I allow the user to enter data into one of the 'editable' cells and change the 'Enter' key into a 'Tab' key, so that the data they entered is in the cell and I tab over to the next 'editable' cell, even if it is in the next row?

Nov 10, 2009I added a DVG to the form. Then I clicked on the small box and selected a data source through the design screen. I chose the connection and then the sproc to get the data. This all works fine. That was added in the Load sub automatically. I will make changes to the cells by code rather than allowing the user to change the cells themselves. Then I want to click a button and save the changes to the table. Everything I have tried does not work.
View 7 RepliesSearch A Access Db Via A TextBox1 A Button1 And A Dataviewgrid?
Feb 15, 2012I am trying to search a Access Db via a TextBox1 a Button1 and a dataviewgrid.My sql statement loks like this:
Select LastName FROM Clients WHERE (LastName LIKE 'TextBox1.text')
This doesn't work I have tried '" & "' around the textbox words I've tried '& TexBox1 &'. This I tried to learn from Data over forms video-- LIKE @LastName +'%' that really didn't work. If I use = "Bla bla" it will work but the LIKE word does not. Even a point in the right direction. I've spent many many many hours on this. And what makes me mad is I've done it somhow before even with a combobox as a variable in the SELECT "var" but anywayI'm wondering now if the LIKE statement isn't used in Access? and if the % wildcard is used in Access?

Saving Changed Data Before DataViewGrid Selection (Row) Changed?
Jan 20, 2010on my Form I have a DataViewGrid and some textboxes with a save button (they are filled with additional data of the selected row).Save is disabled first, when I change something in the textboxes the save button is enabled.When the user changes a gow in the grid, I want to ask before changing the grid row, if he wants to save (if the button is enabled).I am using RowEnter but this is too late, then the selected row already changed (and my textboxes already got new data)...What event can I use to ask if I should save stuff before the user changes a row?Something like BeforeRowChanging with a chance to cancel changing the row?

File I/O And Registry :: Opening A Text File Into Multiple Text Boxes Using Loops And Arrays
May 20, 2009So I'm in the final stages of finishing a program I've been working on for nearly a year now, and this is basically my final hurdle. The Save dialogue is working beautifully, with 'flags' in order to switch it over from the regular input into text boxes to the Listbox input protocol.
However, I'm having a *** of a time getting it to take lines from the text file and put them in the proper text box. Here is an example file:
Quote:
SHOWNAME
CALLNAME
BREED
[Code]....
So with the sample file I provided above, in the textbox named callNameText would appear "SHOWNAME", and so on and so forth. With this build, I get a NullReferenceException on the "Me.Controls(strboxNames(i)).Text() = strAllText(ati)" line.

Scan A Text File To Determine If It Is A Text File And If It Contains Any Non-ASCII Characters?
Jan 27, 2012what would be the optimum code in VB2010 that check a file to determine:
1) is it a text file, and
2) if it is a text file, does it contain any non-ASCII characters
Note that LF, CR, and EOF would be expected, and should not be flagged. I can think of 3 - 4 ways to do it, but there may be a 'best' way in terms of simplicity and speed.

View 4 RepliesCreate And Write To A New Text File From An Existing Text File?
Sep 2, 2009I have a very large text file about 4 million lines that I would like to separate into several small text files based on the strings contained in the first column of the text file. I want to open the large text file, choose the lines that apply, create a new text file with a name that has a number at the end of which will match up with the value in the first column of the text file. I want to then copy the applicable lines to the new small text file, save and close it. I'm not sure how to go about doing this after opening the large text file and using the readline method. What if the folder does not exist? Do we have to create it? I want this procedure to be general, as there could be up to 25 million lines in the text file.
