I have managed to make use of the DwmExtendFrameIntoClientArea in Vista/7 to extend the glass effect into a form. However I cannot get this to happen on a form which is set as an mdi container. The glass portion just doesn't draw any more - it appears white. Note I'm not talking about the children inside the mdi parent, but on the actual main form itself.
Does anyone have any suggestions on how to get this working?

Anyone ever tried to get additional areas of glass on an mdi form?

Have you tried the sample that MSDN[^] provides? There are also some handy "How to" links on the bottom of that page

Hello All,
Is there a way to change the background color of single word in textbox. I know it can be done in richtextbox, but i am looking for textbox.
Thanks

No way. Use RTB.

RTB is heavy for my scenario, i was thinking whether can be done by overriding OnPaint/WndProc?
Thanks

You can paint anything you want on any Control you choose, so the Form itself, or a Panel, would be fine. Why still use a Label if it doesn't do what you want? You still need to tell it somehow which parts need which colors.

What do you think base.OnPaint(e); would do for a Label?

text should be selectable.

I don't think OnPaint() contributes to selection.

You can't do this in the TextBox control. However, you could create your own control that derives from TextBox and override the Paint method to do whatever you wish. Of course you'd have to come up with some way of specifying which word(s) have different colour backgrounds. Seems like a lot of work when RichTextBox already does this.
while (e) { Coyote(); }

Hi
I have written a small UserControl that, at the moment, only overrides the OnPaint event without anything else. However, the content I am drawing in the control is sometimes larger than the display-area itself, so I want to implement scrollbar-functionality that allows the user to scroll if the content does not fit the screen.
I have googled a bit for this topic, but can not find any good information, and my book only tells me how to draw UserControls, not how to implement scrollbars. Any ideas where I can get started with this?
Appreciate any help

Hello.
1) Put your UserControl in a new Panel.
2) Set the AutoScroll property of the Panel to "true".
Enjoy

i have created function in class file.
Public Shared Function dsCntrctET() As DataSet
Dim sqlCntrct As String = "Select * from CNTRCT_ET where CNTRCT_ID=" & CISCNO
Dim cmdCISContract As New OracleCommand
Dim daCISCntrct As New OracleDataAdapter
Dim dsCISCntrct As New DataSet
Dim cmdCISBuilder As New OracleCommandBuilder
Try
With cmdCISContract
.Transaction = myTransCIS
.CommandText = sqlCntrct
.Connection = cnCIS
End With
daCISCntrct = New OracleDataAdapter(cmdCISContract)
daCISCntrct.FillSchema(dsCISCntrct, SchemaType.Source)
cmdCISBuilder = New OracleCommandBuilder(daCISCntrct)
With daCISCntrct
.TableMappings.Add("Table", "CNTRCT_ET")
.Fill(dsCISCntrct)
.SelectCommand = cmdCISContract
.InsertCommand = cmdCISBuilder.GetInsertCommand
.UpdateCommand = cmdCISBuilder.GetUpdateCommand
.DeleteCommand = cmdCISBuilder.GetDeleteCommand
End With
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
Return (dsCISCntrct)
End Function
it returns dataset that i can use for getting value from table.
but while saving data, i have to use dataadapter for da.update(ds,"table") and ds.acceptchanges.
this i have to use in multiple forms as this data comes from 3rd party so i dont want to write this in every form . so i thought how to return data adapter and dataset from the same function. as i wanted to use daCISCntrct and dsCISCntrct.

Ummm...it doesn't work that way. This is part where YOU write the code. We'll help when you run into a specific problem. But, noone is going to write your code for you.

< this contains the original Lounge post and content of material I deliberately left out of the Lounge post : feeling it was more appropriate here >
Hi,
I'm delighted to see that Jeff Anderson his taken latest version of AlphaForm[^], which was being sold as shareware, and now made it available to us, under the Code Project license, free !
I've created a "stress test" example of using Jeff's code that will move quite smoothly with virtually zero flicker, at run-time on an older system with no graphics card (i.e., using motherboard/CPU integration of all rendering) : PIV single core, 2.93 mhz, XP Pro SP 3, VS Studio 2010 beta, FrameWork 4.0, which I consider excellent since the load on the CPU for calculating the non-rectangular clipping regions must be high.
This example uses a .png bitmap saved in PhotoShop CS 4 as 24-bit .png with transparency, size 800x600, which includes one main content area, and two other content areas which are disconnected from the main content area (i.e., the form has non-overlapping areas of transparency : contains "holes") : inside this form there are two torodial areas cut-out from the main content area through which the underlying WinForm can be shown, and on which controls to be used at runtime can be placed. The source graphics (the complete images, source and the image mask files) I have optimized down to under 500k total using very valuable hints and tips found here[^]. I suspect further optimization is possible (particularly on the mask image, and I am experimenting with that trying to find the optimum level of reduction possible).
You can see the source image I'm using here[^], and the clipping mask image here[^].
These images are based on an excerpt from an image[^] in the public domain shown on Wikipedia, they are not original. The image is from a detail of a bronze frieze dating back probably a least 2000-2200 years ago, at Sarnath in India, showing the teacher born as Siddhartha of the Sakyas, and later known as Gautama the Buddha, giving what has become known as the "turning of the wheel" teaching that is believed, by Buddhists, to have "set in motion" (in a non-singular way [from the Theravadan Buddhist point of view]) the insights and practices that have led to what we now know as Buddhism. I was in Sarnath in October of 1975, and had a wonderful time there, even saw a live deer in the park !
If I reach the point where I feel I have enough mastery of Jeff's code that I can modify a few things, and have something substantial to say about using that modified version, or feel I have something useful to add about how to optimize use of it (or its source graphics files), I'll do a brief write-up, and post a link to it here (the WinForms forum) : hope you might do likewise if you use it and modify it.
So, thanks Jeff !
best, Bill
