View 4 Repliesi have wrote a program that allows users to open and save text files etc and it all works fine. All i was hoping to find out is if it is possible to specify the initial folder you are taken to when using the OpenFileDialog. This would be useful as the users only open and edit files from one folder which takes quite a bit of drilling down to to find.

I am looking for ways to retrieve data from textfile and save it into access database. Currently, I am doing a attendance record project. I need to save the attendance record which is given in a text file to the database. The version of VB i using is VB 2008.
The content of the text file look like this:
E010,2009/06,06/29/2009 7:44:45AM,06/29/2009 15:00:55PM,JUR

In My Form I have "DataGridView1" and Button1 "Save as Word file" button2 "Open from file"
View 2 RepliesLet's say I have an edit view that is strongly-typed to a table called "MyData". The view has multiple tabs, each with several different fields from the table. For performance, the data is only loaded when the tab is viewed, so if you only edit a field on tab 1 and submit the form, the data for tab 2 will not be loaded.
The problem I'm running into is on the submit. I'm doing the typical routine of finding the existing record in the database and updating the passed values:
<AcceptVerbs(HttpVerbs.Post)> _
Function Edit(ByVal data As MyData) As ActionResult
Using dc = New MyDataContext
[Code].....
However, this method doesn't know which tabs were loaded, so if the tab with "desc" on it is not loaded, this method thinks the user blanked out the "desc" field, and sends NULL to the database.
How can I construct this so that only loaded fields are sent to the database, and unloaded fields are ignored?
I'm writing a forms application. I'm adding a piece that allows you to double click on a row of a datagridview control to open a new form with more details. These additional details are pulled from a database, which takes a bit of time to finish.If I run the DB query from the form's load event, the form doesn't show up until everything in the load event has completed, which can take several seconds.I want the form to show up instantly when you double click, and all of the fields to be populated once the data is ready.Is there an event I should be using other than Load?
View 6 RepliesI have about 4000 objects of a class, each object with 20 members/variables, integers and strings, total about 80000.
I would like to save these to a file, and read them back into objects when the program starts up.
How would I do this in order to keep track of each variable? I was planning to have each line in the file representing the variables of 1 object. Hence 4000 lines. But basically I'm just looking for the easiest way to save and retrieve this data. Should I first convert the objects to an array of strings?
I have the following code to retrieve a string value from the registry.
Dim retval As String = String.Empty
Try

The problem is that if sValue doesn't exist, it generates a ManagementException. I want those errors ignored because I don't care if the value doesn't exist, it's entirely possible and acceptable. How can I "accept" those errors but display all others?
I know how to get a list of files in a local Windows machine's specific directory:
Dim dirInfo As DirectoryInfo = New DirectoryInfo("C:Temp")
Dim fileListing() As FileInfo = dirInfo.GetFiles()
But how do I use this class for a mainframe system where user ID, password and 'change directory' command are needed?
When I attempt to just access the server without credentials and just do the Windows version and use the syntax "\server_nameAUTO:RPTS.", where 'AUTO:RPTS.' is the mainframe directory name I get the following error: "The given path's format is not supported."
When I just use '\server_name' I get: "The UNC path should be of the form \servershare."

View 4 RepliesI'm using VB.NET in Visual Studio 2008 in a Vista 64-bit OS. I'm trying to find an easy way (there must be one) to quickly retrieve from the registry the application file name and path to use in a Shell command to open a particular file. Specifically, I want the user in my app to be able to click on a PDF file and have the app open that PDF file using the application associated with PDF file types - Acrobat Reader, for example. Anyone have any suggestions as to proper coding & syntax for the following sequence?:
(1) Get name of .exe file associated with .pdf file type (most likely from the HKey Root Classes hive)
(2) Get path for the .exe file
(3) Shell("[pathname]appname.exe filename.pdf")
I've spent a couple of hours looking through the forums and haven't found what I'm looking for.
