That really depends on HOW you're allocating the memory.

I need to impersonate the user to logged in to the system .The process of impersonation should be like this

1) The user will input the username to be impersonate and passwd

2) There will be a dummy user in the system .

3) I need to read all the privilages for the inputted user

4) Then the dummy user will be logged in to the system with all the

privilages of the inputted user

The purpose of this is whether i inputted administrator or guest user ,the logged user will be dummy with the admin/guest privilges

Can any body tell me how can i achieve this

The whole thing should be worked in winNT series and winXP series (including vista )

Its a servie application

And for what reason, might I ask, would you want to impersonate a user?
Forgive me if your intentions are good, but this sounds like a question better asked at http://www.offensivecomputing.net/[^]

Unfortunately there is no similar Data Grid Control in MFC!? So there is no way to code a similar approach in Visual C++ / MFC.

If you would need such a control for MFC have a look on

http://www.codeproject.com/KB/miscctrl/gridctrl.aspx[^]

or

http://www.codeproject.com/KB/MFC/UltimateGrid.aspx[^]

In case you needed the code in Managed/C++ this is the wrong forum. Roll eyes | :rolleyes:

I'm sorry but you cannot translate this print approach to plain C++, since the infrastructure isn't there. Maybe this article will be helpful http://www.codeproject.com/KB/printing/printingmadeeasy.aspx[^] or even better just do a search on MFC and print.

So long,

In properties, there's a member 'border' - it can take various values resizing, dialog frame, none, thin. check it.

Hi all,

I would like to write program, hardware info - like cpu-Z(it's realy great tool!).

I tried WMI, but I wasn't able to get memory type (DDR,DDR2), frequency and other things.

What should I focus in?

Could you help me?

Thanks.

WMI is useful, but accesses a HUGE number of classes, often with names that don't seem to accurately describe the information that is available. If you have, WMI CIM Studio[^], that utility is the best place to start looking for the information. This is available as the WMI Adminstrative Tools download for Windows XP[^]
For instance, when you start WMI CIM Studio, you want to view instances of the Win32_PhysicalMemory class[^] on your computer. Read down the page of the documentation until you locate the property, MemoryType.
This information is often reported by the device driver (in this case), and may not be available, depending on how the driver is implemented.
Once you know the information is available it is a simple matter to code the WMI query, but locating it initially, especially if you don't even know where to look can be very time comsuming.
Read through the documentation that comes with your Visual Studio version for the Win32_classes, this can be helpful.
This MSDN Code Example demonstrates How To Get WMI Information From Your Local Computer[^]

Thank you for reply,

I know Win32_PhysicalMemory class, there is the MemoryType property. But on the Windows XP prof. with sp2 I wasn't able to get proper MemoryType-DDR2, it returns unknown memory type. I tried it on 100 machines. I also had a problem with memory speed(it depends on hardware I think).

Cpu-Z returns corect result(memory type and speed).

Does it exist another solution?

Thanks.

Ah,...I was wondering how many queries you'd already tried. That's the problem with WMI, it often doesn't produce the results you need. But, it's the logical place to start.
I went over to the CPUID Developer System Information SDK site[^], and I got the impression that they did alot of research into the various hardware capabilities. The promotional material at the site states: "At the core of the CPUID kits is a powerful hardware detection engine based on a kernel-mode software driver".
Also, "CPU-Z benefits from a great support of the hardware industry, resulting in the best source of information and a quick reactivity in the support of latest technologies.'

...This is WAY BEYOND WMI,...

I agree. I had the same problem with my laptop sound card. Neither WMI nor the registry contained any useful information at all, except the trade name and manufacturer of the device.
I happened to run into this article: What Every Programmer Should Know About Memory[^], it might give you some ideas (although it just concerns memory hardware).

Handling script errors in webbrowser & IOleCommandTarget Implementation

Samir Lahad4-Jul-08 23:19

4-Jul-08 23:19

Hello,

I have a Dialog application derived from CDialog. I've added a Webbrowser control[^] to the dialog.
I want to handle scripting errors that appear when certain URLs are opened.
I read this article about the subject "How to handle script errors as a WebBrowser control host[^]"

I don't know how to implement Iolecommandtarget interface and how to add "Exec" function. I read this article[^]
Should I do the steps mentioned in the article with the CDialog-derived class? What should I do after that to include Exec method?
I am missing the connection between the second article and the first one.

Regards,

Sam

Get started with C++ for simple GUI apps

Hi, I want to build simple GUI Applications/Utilities with C++ on Windows. Please let me know which free softwares can I use. I don't want C++.NET ( I know C#) just plain C++. C# is good but requires .NET runtime, which increases runtime memory usage, and I guess so would be the case with C++.NET. So I want to build in C++; fast and less memory usage.

Thanks

Please excuse my lack of knowledge (and stupidity). MS Visual Studio is one huge bundle. I need something under 50 MB. I checked Turbo C++ explorer which also is above 300 MB. There must be tools available which are

Free
have IDE
Small Package
Allow building Windows GUI Apps

Thanks....
