Why do you need the bitmap as an intermediate step ? That's the step that is going to make this very hard indeed.

i quite weak but i hv unreasonable idea it gives me error...error given was Error

<br />
With Me<br />
if btnlogin.Text=true then<br />
.LOGIN_OUTTableAdapter.InsertQueryEmp(.Login_DateDateTimePicker.Value)<br />
.LOGIN_OUTTableAdapter.Fill(.Definition_dbDataSet._LOGIN)<br />
else<br />
.LOGIN_OUTTableAdapter.InsertQueryEmp(.Login_DateDateTimePicker.Value)<br />
.LOGIN_OUTTableAdapter.Fill(.Definition_dbDataSet._LOGIN_OUT)<br />
End If<br />
end with<br />
from query
INSERT INTO `LOGIN/OUT` (`Log_No`, `LogIn_time`, `Login_Date`, `Emp_ID`) VALUES (?, ddMMyyyy, HHmmss, ?)
datype i'm using is data/time
can any 1 help me correct it...thanks in advanced

this is the error given..

That error says that you didn't supply a value for a parameter.
Looking at this code, it wouldn't work, even if it did compile. Your if statement doesn't make any sense at all.
if btnLogin.Text=true then
You comparing the Text property of a button to a boolean value?? Why?? Does this button actually say "true" on it when you click it??
I would highly suggest picking up a beginners book on VB.NET and working through it. You're missing some very basic (VB.NET 101) type concepts, and it's limiting your ability to write code and out ability to help you fix it.

actually tht is a part...my question is ragard once user enter their password..the datetimepicker will automatically store into database..
Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLogin.Click<br />
<br />
Dim Emp_IDDataRow As DataRow<br />
Emp_IDDataRow = Comdataset.EMPLOYEE_DETAIL.FindByEmp_ID(txtID.Text)<br />
<br />
If Emp_IDDataRow IsNot Nothing Then<br />
If txtPass.Text = Emp_IDDataRow!Password.ToString Then<br />
MessageBox.Show("Login Successful!", "infor", MessageBoxButtons.OK, MessageBoxIcon.Information)<br />
With Me<br />
if txtPass.text=true then<br />
.LOGIN_OUTTableAdapter.InsertQueryEmp(.Login_DateDateTimePicker.Value)<br />
.LOGIN_OUTTableAdapter.Fill(.Definition_dbDataSet._LOGIN_OUT)<br />
Else<br />
(part below for logout)<code><br />
.LOGIN_OUTTableAdapter.InsertQueryEmp(.Login_DateDateTimePicker.Value)<br />
.LOGIN_OUTTableAdapter.Fill(.Definition_dbDataSet._LOGIN_OUT)
End If
End With
Form2.Show()
Else
MessageBox.Show("Invalid Password!", "Error", MessageBoxButtons.RetryCancel, MessageBoxIcon.Error)
End If
Else
MessageBox.Show("Invalid ID", "ERROR", MessageBoxButtons.RetryCancel, MessageBoxIcon.Error)
End If
this maybe can show more..thanks
error given me was

The error is correct, you are not supplying the function with the Emp_ID parameter.
In your code you are only passing a value to the Log_No parameter:
Member 4442916 wrote: .LOGIN_OUTTableAdapter.InsertQueryEmp(.Login_DateDateTimePicker.Value)
In your function you want two parameters to be determined:

I have a problem I have added a command to my crystal report that calls a stored procedure and should turn a number. I have also added a parameter to that procedure to make it dynamic. The problem I am experiencing is that when I bind this result to an unbound field the parameter doesn't change. It is static. And results in an error of having to Verify the Database to update the report. Is there another way I can do this. Is this a glitch with Crystal....

anyone can help me how to operate some code if the text in the textbox change, i want to make the auto send code but i didn't know, so i decide to make send code in textbox code, the situation is when the text in the textbox is change then the code will be operate..
please help me..

have u tried text_changed event...
is the ocde being changed by some internal process i.e. any function...if yes then that function can trigger the event you wanted..

I Wrote The Following Code But It has An Error
Function Fun(Of T)(X as T,Y AS T) AS T
Return X+Y
End Function
The Error Is :
That Operator + Is not Defined In Type T 
''''
Ok But How Can I Make A generic Method To Make A + Math Operation For All Numerical Types
I love Peace And Programming

This isn't going to work, and it's completely useless.
You can't do what you want to do using a generic method. You're not constraining your Types to only value types. The addition operator is not defined for all possible types that you're allowing (which is basically everything), so you'll get this error. The problem is that you can't use the Int32, Int64, Byte, yada, yada, yada, value types as contraints because they are all structures, not classes. You can only use classes and interfaces as Type contraints, and only classes that expose a parameterless constructor. Structures do not following this rule, so they can't be used.

I thought there was a constraint you could use that specified that the object offered mathematical operations ? Will where T: struct do it ?

All the base value type inherit from ValueType (obviously), but I couldn't use ValueType in the constraint at all. It's a MustInherit class with no parameterless constructor. I couldn't find anything that limited the possible types to "math only" implementors, or anything that would describe a type as being one.

Hi,
I have an app that retrieves and calculates a lot of data. The whole process may take about 20 minutes. To prevent the user from thinking that the app has crashed, I added a progress bar, and to give the user a better idea of the progress, I make the form's title bar display a percentage.
The problem is that at pretty much any percentage the form no longer updates itself. The application keeps running, no problem, but the progress bar and percentage in the title bar get stuck, which effectively defeats the purpose.
Can anyone tell me why this may happen ?
Cheers,
Johan

The UI will not respond so long as there are other things to do... looks like all this is in the same thread, maybe you can do your process in a separate thread?

Thanks for the response.
The funny thing is though, that it does work for a while. At the moment the UI freezes, the app is retrieving data from a database with a succession of datareaders. In other words it is repeating the same task over and over (with different parameters each time ofcourse).
If we consider your theory, why does the UI not freeze right away?

Your description of the problem reinforces my theory  You usually find that the UI becomes unresponsive when there are repetitive tasks...

The UI thread is busy doing all of your operations. It would appear that every once in a while, the thread is freed to process the Window's message pump, thereby processing all the WM_PAINT messages for the window, which means you get to see your progressbar and window title updates.
So long as the thread is busy doing other things, these paint messages do not get processed, thereby looking like the application hung.
You have little choice but to move these operations to a seperate thread and have this processing code fire off progress messages every once in a while. The UI thread will be able to process these messages immediately, while your processing thread does it's job. You may want to look into using the BackgroundWorker class make this process easier.

Hello,
Is there a way to define a function that have an optional parameter whith value = today as following:
private function f(optional d as date =today)

Thanks

Yes, VB.NET does support this. I don't use VB.NET, so you'll need to google for the syntax.
