I just tried a search for P2LTCH with google, finding the following block of code here.
void
toggleLed(unsigned char ledMask)
{
#define P2LTCH 0xFF5E /* The address of the I/O register. */
asm {
mov dx, P2LTCH
in al, dx
mov ah, ledMask
xor al, ah
out dx, al
};
}
Reading through this, I thought of your asm statement - In the code you showed using round braces, you used the asm keyword. Later you showed some code with curly braces, however I see that in the seconds code snippet you have used the __asm keyword, instead.
If you haven't already, I'd try the syntax used in the above snippet. I've a very hazy memory that somewhere I read that the __asm keyword is a MS thing. Dunno, too lazy to check. 
Though I do note that in Code::Blocks, asm gets syntax-highlighted, while __asm doesn't..

Actually that is the same I am referring, O'Reillys' book. But it doesn't work for me. Seems to me that my compiler is not support this.
I appreciate your help all the time...

Woooooah! Hold on just a minute. Did you say you're trying this code in mplab?
That code is obviously x86 inline assembly, yet I though MPLab was for embedded devices - i.e mainly PICs.
Looking at your compile log, it seems remarkably similar to the exerpt I just gotfor the HiTech C compiler, as shown below:
Executing: "C:\Program Files (x86)\HI-TECH Software\PICC\9.80\bin\picc.exe" --pass1 C:\Users\enhzflep\Documents\mplab\proj1\..\main.c -q --chip=16F84A -P --runtime=default --opt=default -D__DEBUG=1 -g --asmlist "--errformat=Error [%n] %f; %l.%c %s" "--msgformat=Advisory[%n] %s" "--warnformat=Warning [%n] %f; %l.%c %s"
Error [317] C:\Users\enhzflep\Documents\mplab\proj1\..\main.c; 5.5 "(" expected

Error [314] C:\Users\enhzflep\Documents\mplab\proj1\..\main.c; 15.1 ";" expected
********** Build failed! **********
In that case, I think the problem is something else - i.e No, this compiler
(a) won't accept the asm keyword (but you can easily make functions in asm files then link them together into your program)
and more importantly (just now)
(b) won't build programs that you can run on your PC - I'd have expected to see the code snippet in concern built using VS or GCC.
Though, perhaps I'm just missing something?

This is true (about the double underscore, not your memory).

I reread your original message and it seems you are using MPLAB to build this code. I suggest you check the documentation for your compiler to find out exactly why it complains about this. Are you sure this compiler supports the __asm or asm keywords? You may also be better using the MPLAB forum to get an answer to your question.

Yeah, seems to me that the compiler I am using with the MPLAB is not supporting the syntax. I am searching on the documentation at the min.

You need to terminate the __asm block with a ';'
e.g.
__asm
{
mov eax,0
mov ebx,10
};
Also note that you MUST preserve (push/pop) any registers you use within an __asm block.
Another thing to note when using 'out' instruction - you may trigger an exception because the Windows OS allows only a few 'out' addresses accesses directly like that from user mode programs (ring 3).
If I remember correctly only tho old LPT ports are accessible.

I tried the same too, but no luck.

I don't have a big picture about this in my mind, since I am new to embedded systems yet. However, that information could be a value added. Thanks a lot.

I found the solution my self by referring the MPLAB documentation. Inline assembly need to be wrapped as follows.
#asm
#endasm

Currently I am notifying all the open documents like below.
for(POSITION pos = pDocMgr->GetFirstDocTemplatePosition();pos;)
{
pDocTemp = pDocMgr->GetNextDocTemplate(pos);
for(POSITION postemp = pDocTemp->GetFirstDocPosition();postemp;)
{
pDoc = (CMDITabsDemoDoc*)pDocTemp->GetNextDoc(postemp);
pDoc->Notify(somedata);
}
}
But now I only want to notify to the active document. Which function is available to get the active document?
Note : If there are 4 tabs and tab2 is open and I am having focus on some other dialog then also it should return tab2 as active tab. However if application is minimized then it should return NULL or some other indicator.

You can use CFrameWnd::GetActiveDocument.
This returns the document attached to the currently active view.

I'm still having trouble writing a Mime list to the Metadata file for IIS on 5.5 and 6.0. My Default Documents was working, but stopped, not sure when I broke it.
I can write the Virtual Path, the asp.net Script Maps, Read write permissions.
The default Docs is the LPWSTR pszDefaultDocs[], and the Mime is pszMimes[].
If anybody with Metadata experience can just take a look at it, perhaps it just something real small I missed.
The last time I worked on it, the Mime array write said I did not submit a safe array. The metedata element type for Mimes is a string array. The element type for default docs is just a string.
LPWSTR pszMimes[] = {
L".application, application/x-ms-application",
L".deploy, application/octet-stream",
L".flv, video/x-flv",
L".manifest, application/x-ms-manifest",
L".msp, application/octet-stream",
L".msu, application/octet-stream",
};
dwNumber = sizeof(pszMimes)/sizeof(LPWSTR);
VariantInit(&var);
hr = ADsBuildVarArrayStr(pszMimes, dwNumber, &var);
if (FAILED(hr)) goto CLEANUP;
if ( SUCCEEDED (hr )) {
hr = pADs->PutEx(ADS_PROPERTY_UPDATE, bstr_MimeMap, CComVariant(var) );
}
VariantClear(&var);
LPSAFEARRAY psaMimes;
psaMimes = _create_W3SVC_MimeMap_Array();
VariantInit(&var);
LPWSTR pszDefaultDocs[] = {
L"index.aspx",
L"Default.aspx",
};
dwNumber = sizeof(pszDefaultDocs)/sizeof(LPWSTR);
VariantInit(&var);
hr = ADsBuildVarArrayStr(pszDefaultDocs, dwNumber, &var);
if (SUCCEEDED(hr)) {
hr = pADs->PutEx(ADS_PROPERTY_UPDATE, bstr_DefaultDoc, var);
}
VariantClear(&var);

Well I fixed the DefaultDocs, had the keyname wrong, and I reformatted the pszDefaultDocs
So thanks Fixed.
LPWSTR pszDefaultDocs[] = {
L"index.aspx, default.aspx"
};
dwNumber = sizeof(pszDefaultDocs)/sizeof(LPWSTR);
VariantInit(&var);
hr = ADsBuildVarArrayStr(pszDefaultDocs, dwNumber, &var);
if (SUCCEEDED(hr)) {
hr = pADs->PutEx(ADS_PROPERTY_UPDATE, bstr_DefaultDoc, var);
}
VariantClear(&var);

Well after a day and a half, I can get the pointer, pull the values from the key if there is a key, I can create a new key, and populate the data,
but I can't figure out how to put my data in the safe array.
the PutEx will write the safe array, I just need to get data in it.
My Data
L".application, application/x-ms-application",
L".deploy, application/octet-stream",
L".flv, video/x-flv",
L".manifest, application/x-ms-manifest",
L".msp, application/octet-stream",
L".msu, application/octet-stream",
VariantArray va(cVariants + 1);
SAFEARRAYBOUND saBound = {cVariants, 0};
SafeArray sa(VT_VARIANT, 1, &saBound);
VARIANT varArray;
VariantInit(&varArray);
V_VT(&varArray) = (VT_VARIANT | VT_ARRAY);
V_ARRAY(&varArray) = sa.psa;
for (i = 0; i < cVariants; ++i) {
hr = SafeArrayPutElement(sa.psa, &i, &va.pa[i]);
RETURN_ON_FAILURE(hr);
}
hr = pApp->PutEx(ADS_PROPERTY_UPDATE, bstr_MimeMap, varArray);
hr = pADs->SetInfo();

Hello,
Im using Win7 64 bit,visual studio 2008.
When i build my application i chosse the Win32 option at the top of the vs2008 menu and i compile the project and what i get is:
I can run the application from the vs2008 environment but at the build directory i dont get the exe file.
But when i try to build under x64 option the buld procces doesnt work.
Any body knows what is the problem?
Thanks.

You cannot run the application in the build environment unless the exe file exists. Take another look in your directory tree.

We need more details to be able to offer a suggestion.

Please check the project settings.
Under the project properties>Configuration Properties>General>Output Directory option you will see where the output file is getting created. This setting just might not be there when you are trying to run the project with the X64 option.
Can you please provide more details or fire a search based on the filename on the directory where you expect the exe to be present?

Additionally to what Richard said, if you are working under windows, MSXML[^] might help you to parse XML files.
