I have a Datarow array but now I need to show each row in a windows form so that the user can look through and find a suitable entry. Ideally the form would be like the DataView display with a BindingNavigator to go through the entries one by one. I have searched everywhere for some indication of how to do it but to no avail.

View 1 RepliesI'd like to see how others might handle this scenario and perhaps provide some comments on this particular solution for handling null values. I have run into a situation where my application requires data from an ancillary source that cannot be altered/changed, which of course means dealing with poor database architecture and implementation! In this case, my app is running into errors when attempting to set some form controls (textbox) to values from a single ADO.NET DataRow. Perhaps I should be handling this when attempting to set the controls? Not sure, but here is the current way this is done:
View 7 RepliesA VB routine assembles a string of email addresses. It is sent to the clipboard with
Clipboard.Clear
Clipboard.SetText Atext
Where Atext is the address string The email client is opened with
lRet = ShellExecute(hWnd, "open", "Mailto:", vbNull, vbNull, SW_SHOWNORMAL)
At this point, when the email client is Outlook, the clipboard doesn't show what was added to the Windows clipboard above regardless of whether we use a left click in the BCC box or a CTRL-V.

View 1 RepliesI have two datatables with similar structures that I want to make one existing row to be updated from another datatable.
For example, "tableA" has three columns: "one", "two", and "three"; with "one" being the primary key...
and "tableB" has three columns as well: "one", "two", and "three"; with "one" being the primary key.
Say there is a row on tableA that is different than a row on tableB (with a matching primary key). What I wanted to do, as efficiently as possible, is to take the that row from tableB and replace the one on tableA so it'll be modified.
I'm not sure if there's an easier way of doing that instead of using loops for setting the row's items.
I had created a windows forms application in vb.net. It contained several windows. Now the users of that application are telling me to display all in one main form. They want to see all the details in one form. I had implemented MDI but they want something like tabs. On different tabs different forms should be displayed. How shall I implement this.

I have a program that uses two forms. The program opens to the Main form, and the user can navigate to the other form from the Main form through use of a button. Here's the way I've currently written it: When the Main form loads, it declares and instantiates the other form during the load procedure. When the user presses a button, the second form is displayed by means of the ShowDialog method. On the second form, there is a Return to Main Screen button which closes the second form, bringing the user back to the Main form.
So, here's the structure of the code:
Code:
Public Class frmMainForm
Dim frmSecondForm As New SecondForm
Private Sub btnSecondForm_Click(blah, blah, blah) Handles blah, blah, blah
[CODE]...
Here's my reasoning: Originally, I wrote the code so that a new instance of the second form was created every time the button was pressed. The problem was that whatever data was displayed on the second form, previously, was lost when the user returned to it a second time. Since the user would be switching back and forth between these forms, frequently, I needed that data to persist.
What is the best practice for accomplishing this:
1) Declare and instantiate the second form on program start, as I have done, and use the button simply to show the form?
2) Declare and instantiate the second form each time the button is pressed but maintain the variables on the Main form and pass them ByRef to a custom constructor for the second form? Is this even possible?
3) Something else?
Im trying to create a stopwatch in one form and another form show my progress bar using a combo box for mins and seconds to show the progress bar on form1 1
[Code]...
I am trying to use a progressbar to show on main form and then finish when next form is loaded, I have got this code.
1. When I click on button, it must open next form, but the next form must only open when the data in my list box has been loaded from Access Databse. When I run my program, it only shows the progressbar and don't open the next form.
Main form code:
Public Class Main
Dim PB As ProgressBar
Private Sub main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub

This was a guess, after looking at the Form.ShowDialog method in reflector.My question is, is there a managed call I can make to acheive the same result, and what does a button click do that other clicks don't?
ETA: The problem does not occur if I open the form using a key.
This is a database app where I am trying to check for possible duplicates and give the user the option to keep the new record or assign to an existing record.In form1 the user will enter data into a textbox. I use this information to build a bindingsource.filter. Then I call another form (form2.show()) to display results to user and get user response. This part all works correctly.
The problem is that as soon as form2.show() executes, I loose the contents of the textbox - and it appears that I am no longer in the bindingsource.addnew() method.

I am writing an app that will produce a slide show from a specified directory. The idea is it will ideally include Images, Video clips (via Windows Media), URL's (held in a text file), PDF documents and power point presentations.
Images and media clips aren't an issue. At present I am looking at displaying specified web pages. I am aware that I can use
System.Diagnostics.Process.Start("http://webinta/Pages/Home.htm"
to open a browser window, but I want control of that as after a specified amount of time it needs to close so I can display the next image (media clip, url etc).
