Hi all,
I facing a problem with listview now, now I have data in the listview, when I click on the header of the column1, the search key will be point to column1. Mean that user will search what ever data in column1. When user click on the column2 then the search key will point to column2 no longer in column1 at all. For example, I have 3 column in my listview, 1) Employee No, 2) First Name 3) Second Name, when user click on the header of Employee No, user only can search for employee no not for first name and second name, by the way, user click on the header of first name, the user sure only can search for first name, and no more for employee no and also not for second name. Can anyone help me on this? Thanks.

HI,
Is there way to have the progress bar works according the loading percentage of another application opened from my application?
Thanks.
|
|

No. There is no information that is returned by the system's loader at any time, let alone anything useful for a progress bar.
Your other application would have to expose something like this, but can only do so after it's loaded, started, and initializing itself.

Actually, I just need an indication that the application has loaded. If this is the case, is there any way to do it?

What does that mean? If you talking about the application initializing itself, then yes you can. All you have to do update the ProgressBar in your applications initialization code.
If you're talking about a progress bar while the application is being loaded from disk, then no, you can't. The system Loader doesn't provide any feedback at all. Your ProgressBar would go from 0 to 100% in one step.

Sorry, but I don't really understand what you mean by application initializing itself.
Actually, I just want my application to know when the other application has loaded, so I can make that application the active application at that instance and use sendkeys method. So I thought can set a condition if the progressbar is 100% then I can proceed with Appactive and sendkeys methods. I don't know whether it's appropriate, please advice.
Thanks

As far as the application being loaded is concerned, it's when the next statement after whatever your using to load the other app executes.
But that's NOT when the other app finishes initializing and doing its own startup stuff. There's no way to tell when that's done. The only thing you can do is write a routine to look for the title of a window in that application every so often.
A ProgressBar isn't going to help you at all...

Good luck! Using SendKeys is not the most reliable way to controlanother application. The best method is if the application exposes a COM object model.

Hi thanx fr ur reply. Actually the date(Date Of Birth) is entered by the user and then we have to check the format. if the format is false then we have to prompt the msgbox says "Invalid format".
Is there anyway to do it.
Help me
Thanks

First from a user stand point I would much rather be able to enter a date in any format and have the program format the date as it wishes. As a user I don't want to have to keep up with Program A uses this date format Program B uses this format.
What I would do is
<br />
If IsDate(Text1.Text) Then<br />
Text1.Text = Format(Text1.Text, "m-d-yyyy")<br />
Else<br />
MsgBox("Invalid Date")<br />
End If<br />
But if you insist on doing what you are doing you could do the following
<br />
if text1.text <> format(text1.text, "mm-dd-yyyy") then<br />
msgbox ("Invalid Format")<br />
end if<br />

Hi everyone,
I was wondering if anyone out there knows of a way to compare a datable to another datatable in VS 2003. I would like to compare the two datatables to see if any updates were made to a datatable. Is there a better way than looping through all the records within each datatable? thanks
|

To best of my knowledge VS 2003 has no such facility, however, there are quite a few third party applications you can use to compare sql database, and some of them also let you generate script to synchronize both copies.
Sql data compare from http://red-gate.com/ is one such example.
Hope this helps.

Thank you Asif for your reply. I guess I will have to find another method to compare two tables.

Hello,
When my combobox loads with the dataset, my textbox control shows only the first record. How can I set the code below so that as I pick a customer name from the combobox, it also shows the same customer name in my textbox?
<br />
Me.cboSelectDealer.Enabled = True<br />
Me.TblCustomerTableAdapter.Fill(Me.CustomerDataset.tblCustomer)<br />
<br />
Me.cboSelectDealer.DataSource = CustomerDataset.Tables("tblCustomer")<br />
Me.cboSelectDealer.DisplayMember = "Cust_Name"<br />
Me.cboSelectDealer.ValueMember = "ID"<br />
<br />
Me.txtCustomerName.DataBindings.Add(New System.Windows.Forms.Binding("Text", Me.CustomerDataset, "tblCustomer.Cust_Name"))
Thanks in advance,
Rashar
