I finally figured out why it's not working. To make my form look nicer, I set my grid's visiblity to false in design, and then set it to true once the entire form has loaded. However, there are certain settings on the grid that just don't seem to take effect if the grid is currently not visible. I guess tooltips is one of those items. (Other ones I've found are fonts/colors/etc.) So I guess I will have to loop through the grid again after I've set the grid's visiblity to true, unless someone else has a workaround for this issue???

the www web ?
The obvious way is to put it in a zip, and give people a link to the .NET framework.

I want to put my question in a more appropriate way.
I am really sorry for the way i put my question.
I am really new to the programming world.
So please pardon me.
I want to deploy it on the web and the user have to open it on the browser like explorer. Its basically a game sort of thing. I want the user to play the game directly on the web browser.
Could any one help me out on this?
Thanking you.

Hi
I need to save an Excel file as (Excel 97-2003)
For the code below, I have a reference to Microsoft Excel 12.0 Object Library, which I assume is for Excel 2007.
When I open a workbook saved as below, I get an error message saying the workbook is not in the expected format.
Previously I used a reference to Excel 10.0 which worked fine, but I cannot find that anymore when adding references.
I guess I have two choices:
a) How do I reference Excel 10.0 Object Library?
or
b) In the code below, what do I replace "FileFormat As Object" with to specify that the file must be saved as an older Version?
Private Sub ExportExcel()<br />
Dim xlApp As New Excel.Application<br />
Dim xlBook As Excel.Workbook<br />
xlBook = xlApp.Workbooks.Add<br />
<br />
'Write stuff to book here...<br />
<br />
xlBook.SaveAs("MyBook.xls", "FileFormat As Object")<br />
xlBook.Close()<br />
xlBook = Nothing<br />
xlApp.Quit()<br />
xlApp = Nothing<br />
GC.Collect()<br />
End Sub
|
|
|
|
|
Found my answer...
Use one of the Interop.Excel.XlFileFormat formats
Interop.Excel.XlFileFormat.xlExcel8 seems to work fine

Hi,
Let me explain step by step,
First: I have a file which gives details of a user as., FName, MName, LName, Address, TestDate, TestResult etc...
Second: I have to import this file and store it in Data Base. And assiagn a unique number to each user.
I am maintaining a Database where candidate details and test details are stored in separate tables using the unique id i created as the key.
Third: If this user to whom i had already assaigned a unique number, will take another test. And again the data is send in the same format (FName, MName, LName, Address, TestDate, TestResult etc...).
Forth: This file does not have any number or a unique field which can differentiate one user with other.
Fifth: In this case i have to only input the test details and not the candidate details as the user is already holding a unique id.
Question 1: How can i differentiate the users from one to another.
Question 2: How can i check wheather the user candidate data is already in the database or not. As generally different users do have same name and common addresses which are very irrelavent to check.

If different users really have the same name and the same address, then you don't have enough information to determine if a user already exists in the database or not.
Experience is the sum of all the mistakes you have done.

i created a new class (called clabel), inherited from label and in this class i override the label's-textproperty :
shared MyText as string
public overrides property text() as string
get
mytext
end get
Set(ByVal Value As string)
mytext= value
end set
end property
in my form's load-event i dynamically added now a number of these new custom-labels, like this:
dim i as integer
for i = 0 to 10
mylabel = new clabel
with mylabel
'size, location...
.text = i
end with
me.controls.add(mylabel)
next i
now i would expect to show each label in its text-property a different number, from 0 to 10.
but they all show the same (highest) number, in this case "10".
why?

It is simply because you are using a shared (static) variable MyText to store and return value of Text property.
Please know that shared (static) variable is a variable which has just one instance which is shared by all instances of objects.
Therefore text property of your all clabel objects will always have same value because they all are pointing to the same MyText variable, and this value will be value last set for MyText, which in this case if 10.
Declare MyText as a Private string variable and your issue will be resolved.
I hope this help  .

How can i convert an rgb image to an YCrCb image??? is there any builtin function for it in .net?? or any other easy way out?
(Jameel)

Where do you hope to use this image ? .NET ( and Windows in general ) can do nothing with it, so the framework isn't going to help you. You'd need to get a library for a format that uses YCrCb.

Hi,
there are some color model conversion articles on CP, here is one of the better ones[^] but I am not sure the one you need is in there.

I tried to use the following code to pass 1-D array value to 2-D array. This code works, but I wonder if there is a more efficient way to implement this. Thanks.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim i As Integer = 0
Dim DeltaGamma As Double = 0.3
Dim DeltaTapPoint As Double = 3
Dim DACArray() As Double = New Double() {1, 3, 5, 7, 9}
Dim NewArray(5, 4) As Double
Do While DeltaGamma > 0.1 And DeltaTapPoint > 2.0
For j = 0 To 4
NewArray(i, j) = DACArray(j)
Next
ProcessArray(DACArray)
i += 1
If i > 5 Then
DeltaGamma = 0.1
DeltaTapPoint = 2
End If
Loop
End Sub
Public Sub ProcessArray(ByRef array() As Double)
Dim j As Integer
For j = 0 To 4
array(j) *= 2
Next
End Sub

Don't think you can get more efficient than that. Unless you do some loop unrolling...
