I've been struggling with this for a week and a half. Time to ask for help. I have a VC++6.0 / MFC application which "hung-up" when the laptop it was running on suspended operation because of power management. The thing is, I really don't want to loose the data that was entered into the program but not saved. So, I have duplicated the problem on another laptop - all I get is a blank window frame where my program should be. I'm trying to use the Visual Studio debugger to "attach to process" and stop it (break). The call stack shows it's in NTDLL, but I can see my program's code space. How can I find out where my document's data is in memory? Ideally, I'd like to be able to dump it to disk, or even better serialize it. At the very least I'd like to inspect it as a class and manually view member data. Any ideas? Thanks!

Wouldn't it be easier to just handle the WM_POWER and/or WM_POWERBROADCAST message(s) and save your data accordingly?

True, but right now the immediate need is to not loose the data from this one instance of the running program. I'll worry about fixing the code later.
Thanks

I've tried two things, first is a process memory dump called cprocess at http://www.nirsoft.net/utils/cprocess.html[^].
The next is a project here on codeproject at http://www.nirsoft.net/utils/cprocess.html[^].
With a running process, using Mdump from codeproject in the link above, I could use the "find" feature to locate user inputted ascii text in a running process. I've yet to try it in a hung-up process. There's no native dump to file in Mdump, but on its own is useful for locating where in memory text is.

As you know, within a pe file, there may be a few icons; but the Windows Explorer shows just one of them in order to show the file to the user. Can you tell me please which ICON within a pe file is shown by the Windows Explorer?
Thank you masters!

Hi,
I'm using Visual Studio 2008 and seem to have a problem with the form designer. I'm new to MFC and want to create a project that allows me to use the form designer. I create a new MFC application form and all the code is created. When I build and run this project, there is a basic window with a few components. However, I can only seem to see the code for this application. Is it possible for my to open this in the form designer and manually edit the form in the editor rather than through code?
Thanks

If you have the Express Edition then no cookie for you: the visual resource editor is not included.

In VC2005 (and I guess it is similar with VC2008), you have to open the resource editor. On the left side, you have your solution explorer (which is listing all the files from your project). If you look carefully, you should see tabs at the bottom, click on the one called "Ressource View" (or Ctrl + shift + e). There you should be able to browse and edit your resources.

Ah, that's perfect, thanks. Would've preferred the easier WinForm methods of having it in the solution, but not complaining

Hello,
I'm communicating with a logic analyzer (HP 1660A) over RS232. I issue a command which tells the analyzer to print screen its display and send it over to the controller (my pc) through serial communication. I'm saving the result (which is usually abut 25kB) to my computer and I would like to view it as a TIFF or other format. The problem is that the response from the analyzer comes in PCL format, therefore suitable to be sent to a printer and printed directly, but not to be opened as an image. I have tried a few PCL to image converters to do the job, I found one which does it properly, however I've used the trial version and I am reluctant to purchase it. I've given you the background of my labour. I would appreciate any kind of help, a reference to the commands in pcl 1 and what should I do in order to extract the data and format it properly from the PCL file. I have no experience with PCL and image processing whatsoever, so please, give me a hand here. Thank you.
P.S. I've obtained the PCL file from the analyzer, both in C# and matlab... I have one slight problem in C# with the serial port control, some images have some uninterpreted characters in the image, when using the above converters. I say all these because I need an algorithm or some indications, no matter the programming language, so please feel free to post.

There are some commercial tools around to do this such as PCLTool SDK but I've never used them. (I resorted to photographing my scope's display to get images). Presumably this is the only format you can get from it?

I've tried using PCLReader, which is freeware, but it has a problem in that it strips about 3 characters from the right hand side of the image (I mean the entire right portion, for a 3 character width). The same issue I have with PclToImage from Oak. The only one that does the job properly is EscapeE from RedTitan, but, unfortunately, this is not free and I work on a school project.
The device accepts commands and queries. When I use a command, I can save the image in TIFF format on a floppy disk, but I am not to use the floppy too often, because it is the only storage medium on the analyzer, and also the boot device and it will break down very fast. So I must use a query, to send the image through RS232 to the pc and the only output type is PCL. Thank you.

I would like to open a URL file("http:\\A\\file.ext"), but I would like to find out if the file is actually there before opening it using ShellExecute. The error codes don't help much, because if the file isn't there, it would still open the browser, but won't display contents, but the error code will still succeed. I tried using ShellExecute( "Find" ) to find out if the file is there before I open it, but I think I may have used it wrong because it never finds it based on the err code (5) that I keep getting. Anybody have an idea of how I can do this ?
Thanks

Is that file on your local file system? If so, then simply try using FileExists[^] to check if it is there before trying to open it in your browser.

Hello,
no, its a web file. I just want to be able to open the file successfully...ShellExecute("open","http:\\www.gooogle.com"..) will return as successful even though it might not be there or no contents displayed.. I would like to check the valididty of the URL before opening it in other words.
Thanks

I believe ShellExecute itself will only report you if it could run the specified/associated application/command, and since you specified something starting with http:\\, it will run the associated browser and feed this to it, and since it CAN run the browser it will say "success", it doesn't care what the browser actually does with the URL. I doubt you can check if the URL is valid or not by using ShellExecute, you will have to either try finding some library or class or such that checks if an URL is valid or not for you, or you will have to do the check yourself. Of course i could be wrong...

INT WSAInstallServiceClass(
__in LPWSASERVICECLASSINFO lpServiceClassInfo
);
typedef struct _WSAServiceClassInfo {
LPGUID lpServiceClassId;
LPTSTR lpszServiceClassName;
DWORD dwCount; LPWSANSCLASSINFO lpClassInfos;
} WSASERVICECLASSINFO, *PWSASERVICECLASSINFOW;
Just a collection of WSANSCLASSINFO?
And the programmer needs to keep the array of WSANSCLASSINFO consistant
(hold some common attributes that make sense to the service class)?
It seems that the consistency is not promised, in another word, the inconsistency can't be detected
mechanically.
============================================
Here is a sample in the book,
the content of the array aNameSpaceClassInfo seems arbitrary, does it?
WSASERVICECLASSINFO sci;
WSANSCLASSINFO aNameSpaceClassInfo[4];
DWORD dwSapId = 200,
dwUdpPort = 5150,
dwZero = 0;
int ret;
memset(&sci, 0, sizeof(sci));
SET_NETWARE_SVCID(&sci.lpServiceClassId, dwSapId);
sci.lpszServiceClassName = (LPSTR)"Widget Server Class";
sci.dwCount = 4;
sci.lpClassInfos = aNameSpaceClassInfo;
memset(aNameSpaceClassInfo, 0, sizeof(WSANSCLASSINFO) * 4);
aNameSpaceClassInfo[0].lpszName = SERVICE_TYPE_VALUE_CONN;
aNameSpaceClassInfo[0].dwNameSpace = NS_NTDS;
aNameSpaceClassInfo[0].dwValueType = REG_DWORD;
aNameSpaceClassInfo[0].dwValueSize = sizeof(DWORD);
aNameSpaceClassInfo[0].lpValue = &dwZero;
aNameSpaceClassInfo[1].lpszName = SERVICE_TYPE_VALUE_UDPPORT;
aNameSpaceClassInfo[1].dwNameSpace = NS_NTDS;
aNameSpaceClassInfo[1].dwValueType = REG_DWORD;
aNameSpaceClassInfo[1].dwValueSize = sizeof(DWORD);
aNameSpaceClassInfo[1].lpValue = &dwUdpPort;
aNameSpaceClassInfo[2].lpszName = SERVICE_TYPE_VALUE_CONN;
aNameSpaceClassInfo[2].dwNameSpace = NS_SAP;
aNameSpaceClassInfo[2].dwValueType = REG_DWORD;
aNameSpaceClassInfo[2].dwValueSize = sizeof(DWORD);
aNameSpaceClassInfo[2].lpValue = &dwZero;
aNameSpaceClassInfo[3].lpszName = SERVICE_TYPE_VALUE_SAPID;
aNameSpaceClassInfo[3].dwNameSpace = NS_SAP;
aNameSpaceClassInfo[3].dwValueType = REG_DWORD;
aNameSpaceClassInfo[3].dwValueSize = sizeof(DWORD);
aNameSpaceClassInfo[3].lpValue = &dwSapId;
WSAInstallServiceClass(&sci);

In MSDN, it says:
A namespace provider is a locally-resident piece of software that knows how to map between the Winsock namespace SPI and some existing namespace (which could be implemented locally or be accessed through the network).
I'm not clear about some concepts:
1. Winsock namespace SPI (and what does SPI stand for here?)
2. some existing namespace
The concepts are too abstract to me, any sample?
Thanks very much.
