View 6 RepliesHow To Maintain Scroll Position In DataGridView
Apr 1, 2010I was wondering if there is a way to keep the same scroll position in a datagrid view as the app jumps around to various rows (driven by the user selecting different timestamps or address). After the jump happens, the horizontal slider moves all the way to the right, but I want it at the same position as before the jump (or at lease go all the way to the left).
I have tried numerous things (datatable.AcceptChanges(), etc) but haven't been able to figure it out yet.

Launch App From Shortcut & Maintain Focus?
Feb 22, 2011I need to launch a mainframe login screen from a shortcut so that the target and start in paths are preserved.
Before I figured out that the 'target' and 'start in' paths were problematic I was calling the .exe from the server using the following code and then sending keystrokes to the mainframe login dialog:
Private Sub btnDB1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDB1.Click
Dim ProcID As Integer
[Code]...
...To launch the app from the shortcut, which works but I then can't call the process ID to set focus and send keystrokes to the login form.

Best Way To Maintain An Autocomplete / Suggest List Across Sessions
Apr 7, 2009I would like to maintain a list of all of the strings entered into a ComboBox across all uses of an application on a given PC, for use as the AutoCompleteSource for that ComboBox, i.e., I enter in "Fred" in the ComboBox, commit the data, close the application, reopen the application, reopen the ComboBox, type "F", receive the suggestion "Fred".Assuming I already have in place code to create and maintain such a list in memory and add new elements to it as they are entered into the ComboBox, etc., what do you suggest as the best way to save/load this data in between sessions?Possible complicating factors: This application will be deployed via OneClick deployment, and will search for updates online every time the application starts. I would prefer that if the application updates, the list still exists after the update has completed.

View 1 RepliesStrip First 75 Characters Of String And Maintain Words
Jan 28, 2011I am trying to strip the first 75 characters from various strings (sentences / phrases) and it seems right but I need to ensure that the now words are truncated in the process. Meaning that if the 75 character is part of a word it needs to fall back to the beginning of the word or nearest space..
I thought of stripping the entire string into separate words and then counting the length of combining the words and stopping when I reach the target but what do I do in the case when it is not a valid sentence just a bunch of characters jammed together. I thought of using grammar parsing tool libraries and parsing into tokens etc but that seems to over complicated.
if text.length() > 75 then
ctext = text.remove(text.length, 75) & "..."
endif
I put elipses at the end but using the above I also get the error:
does anyone have any better suggestions.
VS 2008 - How To Maintain Line Breaks In DB Column
Nov 30, 2011I am reading a field from my database that has line breaks in it and displaying it on an aspx page. I want to maintain the line breaks on the page. I believe this is more of a VB.NET issue than a DB problem. [URL]
So this is what I tried:
If IsDBNull(CourseHours.Value) Then
EventDesription.CourseHours = ""
EventDesription.CourseHours1 = ""
EventDesription.CourseHours2 = ""
EventDesription.CourseHours3 = ""
[Code] .....
I am pretty sure that CourseHours.Value contains the cr-lf's I am looking for. I attached a screen shot of my debugging session. When I query CourseHours.Value I see boxes or squares which I believe is signitying CR-LF. But my split is only ending up with one array element and it is a long string with all the course hours concatenated. What do I need to Split on?
VS 2010 Update Program But Maintain Database?
May 1, 2012using visual studio 2010. I have a vb.net application that needs to be updated periodically. The software stores client lists in a database for the user, but when the user reinstalls the program after I send them an updated publish, the client list database is replaced with a fresh empty database.
Is there a way that the user can reinstall the software without losing their current database?
I don't know if I need to somehow make separate publishes. One for an initial install to set up the database, and then one for updates that leaves the client database untouched? I don't know how to go about it.
