its not working
the below code works for me but Guffa told me that i should use PaintEventArs. If i using the following method to paint i should write the same code on Form_Resize.
is there any another method to show a stretched background image ???
Private Sub Form1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles MyBase.Paint
Me.CreateGraphics.Clear(Me.BackColor)
Me.Graphics.DrawImage(hImg , 0, 0, Me.Width, Me.Height)
End Sub

Use e.Graphics instead of Me.CreateGraphics.

I think I have an alternative way to do this which is more elegant
In the constructor of your class you can add this line:
SetStyle(ControlStyles.ResizeRedraw, true)
then from that point windows will stop sending small redraw to part of the control and assume the whole control needs to be repainted when resized.

Hi don't know if this will help but this is how I add up a column and show in a textbox.
Good luck
For Each NewTotal As DataRow In Me.HorsesDataSet.CHARGES.Rows
If NewTotal("TOTALCOSTFORSERVICES") Is System.Convert.DBNull Then
Else
Nos = Nos + CDbl(NewTotal("TOTALCOSTFORSERVICES"))
End If
Next
txtbxOverallCost.Text = Format(Nos, "£#,##0.00")

Dear friends,
I am getting gdi+ error when using .colordepth in any format (1L in int32, long or just 1L).
what to do?
Heres the code sample.
The error is on the same line.
But taking depth at 24L its working.
I wan't output with 1L only.
Thanks,
ThisEncoderParameters.Param(0) = New EncoderParameter(Encoder.SaveFlag, CType(EncoderValue.MultiFrame, Long))<br />
ThisEncoderParameters.Param(1) = New EncoderParameter(Encoder.ColorDepth, CType(1L, Int32))

This depends on how you're using this, but it looks like the ColorDepth parameter only works with GIF and TIFF files.
|
|
|
|
|
I have been trying this with tif images only.
But don't know why it don't take depth less then 24L
|
|
|
|
|
From what I've been reading, GDI doesn't support 1 bit color depth.

Hello All,
In my application i have to change child form text and label's visible property to false based on some condition like:
In my application MDI form is a startup screen and written the following code
if bvar = false then
dim frm as new frmchild
frm.label1.visible=false
frm.text="Hello"
end if
Presently i have written it in module because it has to be included in either a class or module as per requirement.
But, whenever i execute my application, the label still remains visible and also form text remains the same.
I am using dot net 2003.
anyone who knows, Please help at the earliest how properties can be changed at runtime.
Please provide some code if possible.
Thanks .

Pass the Form object to module when you call the Module.

Hi you need to hold the all object of the form. So
Create the all form object out of the mdi form load method and call module and pass each form object to the module.
Or if got any error messages then post here.

Access the items of Arraylist like myarraylist(0), myarraylist(1) and so on. Note Arraylist item will return object so you have to cast it into the correct object (2D array in your case).

Hello,
I am facing the problem in accessing the child form control property.
In my application depend upon certain condition , i have to hide some controls of some child forms.
I have created a module wherein writen a Public procedure to hide one of the child form's control
and call the procedure in MDI forms load event.
But, Whenver i am executing the application , code doen't take any effect and control still remain s visible.
Here is the code:
Module Mod1
Public sub HideControl(byval var as boolean)
if var=false then
Dim frmName As frmSearch
If frmName Is Nothing Then
frmName = New frmSearch
frmName.label1.Visible = false
End If
endif
end sub
end module
This is first way i tried.
Second way : I have defined a property for accessing the form instance and with this instance accessing the control as below:
''' global variables
Private Shared SearchInstance As frmSearch
Private Shared bSearchInit As Boolean
Public Shared Property DefInstance() As frmSearch
Get
If SearchInstance Is Nothing OrElse SearchInstance.IsDisposed Then
bSearchInit = True
SearchInstance = New frmSearch
bSearchInit = False
End If
DefInstance = SearchInstance
End Get
Set(ByVal Value As frmSearch)
SearchInstance = Value
End Set
End Property
Using this property accessing cotrol and setting its property in module as:
frmSearch.DefInstance.label1.Visible = false
None of the these codes seems to be working.
when i open that child form i still found that label visible.
Please anyone who knows the answer let me know, how to do it.
Please Give some code , its urgent as i am unable to proceed further.
Any help will be highly appreciated.
Thanks

I think you might be making things a bit to complicated.
This is how I would do it:
in the mdi set a property (shared one) to true or false (for further referance: b1)
then when you open the child forms in the contstructor (or load) check this property and set you're controls to visible or not.
child.label1.visible= mdi.b1(shared property)
...
if you also need to change the visibility of you're child forms while they already exist you can run thru them everytime the property is set:
public property b1 as boolean
get
return ...
end get
set (value as boolean)
for each frm as form in mdi.MdiChildren
if frm.gettype.equals(gettype(frmsearch)) then
dim f as form = frm
f.label1.visible = 'true or false
end if
next
end set
hope this helps
