Hi folks,
I need (a Tool or a Hint) to convert programmatically a webpage (URL) to a thumbnail,
even using Internet Explorer as a parsing unit.
There's many tools over the Internet, but i figure out that it can be possible
using the GDI+ API's in the .net Framework.
Nobody knows how to perform this task?
Thanks i.a. to all that read this topic.

This is done in VB6.0
I have closed the application, the workbook and quited the excel application but the excel is still in memory.
Actually i have some macros in my excel .It might be creating the problem,i guess now.
and from one site i have seen that i have to ensure whether the excel has been saved or not (I am giving book.save in the code)
for that i did
while (not workbook1.Saved)
DoEvents
wend
But it didnt work...then,
I closed each and every workbooks by putting it in a loop.
But still excel remains in memory .I could open only if i have closed the excel.exe from the taskbar.Please help...
Thanks

can anybody tell me how i can communicate with the hardware through serial port in VB.NET.

What you send over the serial port will be VERY device specific.
How you send it will depend on the version of the .NET Framework you're using.
For .NET 1.0 and 1.1, you'll have to find a 3rd party Serial Port library (unless you want to write your own). I suggest searching GotDotNet.com for "serial port" to find one.
For .NET 2.0, you can use the SerialPort[^] class.
I don't have any examples for either of them. You'll have to do some Googling yourself.

Hi!
Trying to get the handle of the window (actual app, not textbox or other window) that was active before I clicked in my own win form? I've tried GetActiveWindow and GetWindow with the GW_HWNDNEXT and GW_HWNDPREV paremeters but I'm no expert using Windows API's and can't seem to get it to work:
'Get the next window handle.
Dim vWndActive As IntPtr = GetActiveWindow
Dim vWndPrev As IntPtr = GetWindow(vWndActive, GW_HWNDPREV) 'this line doesn't work!!
'Activate previously active window
Dim vClassName As String = Space(256)
GetWindowText(vWndPrev, vClassName, vClassName.Length)
AppActivate(vClassName)
I know this code doesn't work and may not make much sense but it's the stripped version of what I'm trying to do and I think you get the point.
(Ps. Using vb.net)

There is no function that will return the previously active window. AFAIK, the only reliable way would be to override your window's WndProc and look for the WM_ACTIVATE message. If the low order word of the wParam field of this message contains the WA_ACTIVE or WA_CLICKACTIVE message, the lParam of the message will contain the handle to the window that lost the focus.
Once this message is processed by your application, it's way too late to call any function to find out what the previous window was.

What are the list of events that get fired during the life cycle of a Win Form in .NET, I mean when it is created and destroyed.

Thats for Visual Studio 2005. Is it the same for Winforms in Visual Studio 2003?

No, that's for Windows Forms in .NET. VB.NET 2005 added the little note in the middle of the page, but the order of events has not changed in the Form class since .NET 1.0 was released.

Hi,
there are many articles[^] here on CodeProject showing how to do this.
|
|
|
|

Hey,
Thanks for the Prompt & precise reply.
But these all articles I have senn they are implementing the Single Column
Combo Box . WhichI have done already.
My problem is to embed the MultiCOlumn ComboBox inside datagrid
I have seen some multi Column Combobox User Controls Examples also
on CodeProject.com iteself.
But they all are not fully embedded with the wnforms datagrid.
your valuable suggestion are highly appreciated.
thanks a lot

You will probably will have to make this yourself. I would suggest you look into one the the articles showing how to add a normal combobox into the grid and try to exchange the combobox with one of the multicolumn comboboxes[^] already available.

Hey Robert,
Thanks again for this direction.
I will check these articles
& Try to implement
Thank you very much for this direction
thanks a lot

on the top-right corner of the form in pocket pc there is a close button, now i would like to disable it, so do not make it use to close this form, so how?what codes can be used?
thanx
go ahead...do best on my works....
|

Haven't tried it but in WinForms you would catch the Closing event of the form (or override OnClosing) and set the Cancel property of the given event arguments to true.
Probably its the same for pocket pc development...
|
|
|
|
|
You could set the forms ControlBox property to False although that will also remove the minimize and maximize buttons. If these aren't used then you're good to go.

Hi,
Uhm... Ok, I know I need to have a crash course in this whole Bit / Byte / Char thing, but I'm hoping as per usual, that the quickest and best way for me to learn this, will be learning by example...
I get a value from somewhere in memory (Handled by a IPC which, I have *nothing* to do with). Value: 0x3500 (Or rather, &H3500 I believe?)
How do I convert that back to, say a String? Or a Integer?
According to the associated documentation:
Version number:
The HIWORD (i.e. bytes 3306-7) gives the main version as BCD x 1000: e.g. 0x1998 for 1.998
The LOWORD (bytes 3304-5) gives the Interim build letter: 0=none, 1-26=a-z: e.g. 0x0005 = 'e'
The value is 4 Bits long. In (I presume VB 2002), this apparently works:
<br />
Version = Chr(Asc("0") + (&HF And (Shift(myModule.Mod_Version, 28, RightShift)))) & "." & _<br />
Chr(Asc("0") + (&HF And (Shift(myModule.Mod_Version, 24, RightShift)))) & _<br />
Chr(Asc("0") + (&HF And (Shift(myModule.Mod_Version, 20, RightShift)))) & _<br />
Chr(Asc("0") + (&HF And (Shift(myModule.Mod_Version, 16, RightShift))))<br />
I know I may be asking allot here, but I'm more after someone explaining to me HOW this work, rather than just giving me example code (though, a example or 10 would be good as well). I have THOUSANDS of these magical 'Bits' and 'Byte Array' offsets that I need to read, manipulate, and write... Some of them I managed to get right (mostly the ones that returns Byte Arrays), but most of them, is a major battle to me.
From what I understand, I know that I need to loop through all the Bits in the Byte - and convert the Bits to whatever I want (Strings / Integers / etc) as I go along... But... How?? 
Thanks guys / gals,
Hopefully I'll understand this all better in bit (or, should that be byte?)

How could I set values partially for the 2nd and third brach of the shown tree above and how could I know if the specific node is a child node of its root? and one more major question how could I check if any given text exists in the tree.

What???????????????? Values? What values?

Huh??? If a node has a parent, it's got a root too. If not, it is the root.
B Journey wrote: how could I check if any given text exists in the tree
This is a recursive routine. Given a starting node and the text to search for, you'll have to check each child node for the text. During the enumeration of the children, check each child for child nodes. If a child has children, the routine calls itself with the new starting node and the same text to search for. The routine will have to return an array of node objects (or whatever else your looking for).
