hi CPIans
I am struggling with a WebService Project.
I am explaining the issue.
I have created a web services which process ASP Pages. Whenever a client connect to my service I am creating a thread for handling its request. In this thread, I am calling VBScript Engine component for execute ASP Page.
Here my webservice is used as a gateway. In side my ASPPage I am creating XMLDomDcoument and HTTPRequest Object . I have listed here the Code
Processing flow
1. Loading XML Content from Request Object to XMLDOMDocument
2. Opening our DataCenter Server’s ASP Page by MSXML2.XMLHTTP Object
3. Sending the XMLDOMDocument by MSXML2.XMLHTTP object
<!--#include file="dataCenter.asp"--><br />
<% Set objXMLDocument = CreateObject("MSXML2.DOMDocument")<br />
dataCenter=dataCenter & Mid(Request.ServerVariables("URL"), InStrRev(Request.ServerVariables("URL"), "/")+1) & "?rt=GWAY"<br />
Set objHTTPRequest = CreateObject("MSXML2.XMLHTTP")<br />
objXMLDocument.load(Request)<br />
objHTTPRequest.open "POST", dataCenter, False <br />
objHTTPRequest.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"<br />
objHTTPRequest.send objXMLDocument<br />
ret = objHTTPRequest.responseText<br />
Response.Write ret<br />
Set objXMLDocument = Nothing<br />
Set objHTTPRequest = Nothing<br />
%>
Everything working fine for some time (likely1 hour or 55 minutes ) (it is varying for each server) After that , My Script engine is throwing a Error like
“ Failed to Create Object CreateObject("MSXML2.DOMDocument") “ 
After restarting my webserice, ii working fine and come to same status as mention above
While running webservice , every execution of ASP , handles are increase gradually
I have question on this issue
1. Whether it is VBScript Engine Issue 
2. Whether it is MSXML2.DOMDocument Issue
Thanks in advance

We have an application, say A which is used to start some other applications (B,C,D). That is when A starts, it also starts B,C and D. Now if any of B,C or D has been started manually, A should not start these applications. I would like to know whether we can implement such a scenario using mutex.

Yes you can use a named Mutex. If the creation fails with already exists then don't start the app. You will have to use separate names for each app (B, C and D).

I am writing this program where I read in a line of text.
I am able to enter the text just fine and it stores okay, but then when I go to prompt user for another entry (such as an integer) I get an infinite loop because it is waiting for a valid entry.
example:
cout << "please enter a string of characters.";
cin.getline(tempstringgoeshere, BUFFER);
int selection = 0;
while(selection < 1 || selection > 5)
{
cout << "Please make a selection:";
cin >> selection; // DOES NOT LET ME ENTER ANYTHING HERE - GOES PAST
}
Suggestions?
Thanks,
G

Its probably because in the first getline the BUFFER is too small or the user is entering a string whose length in bigger than BUFFER.

I think. In this case, it will go in to loop for characters only.
Might be problem with overload of operator >> with int parameter. It is not handling char properly.

Hello,
i have an question to, why dont use cin directly like this:
cin >> tempstring; // 
with best regards
break;

What is the value of BUFFER and how many characters are you entering? You'll quickly find that tempstringgoeshere is not large enough. Use a string type instead of a char type.

Unless your input is an array of strings then use cin>>tempstring otherwise
use cin.getline(tempstring, MAXBUFFERSIZE, '\n'); this function takes 3 parameters, and the last one is the delimiter i.e. when to signal the function to return.

You can write one. Also, a Google search on "directshow filter rotate video" may point you
to some helpful sites.
At what point in the filter graph do you want to rotate?

I have a file, data.dat, that contains a memory map that is used in an other software solution written in an other language. The file contains information in the format:
Address1 0x0000
Address2 0x1000
Address3 0x2000
Address4 0x3000
...
I need to access this file in runtime from my program written VC++ Express. I would like to include the data.dat-file like a resource file when buildning my program. My question is:
How do I include this file as a resource-file and how do I access the file and read information from it? Code examples would be greate.
Best regards

Add the file as a custom resource.
Then use FindResource, LoadResource and LockResource in that order.
This will give you a pointer from which you can read the data.

Thanks for the reply,
Unfortunately I can't find what namespace to use or what files to #include to get access to those functions? Do I need .NET framework 3.0 installed?
Thanks in advanced

Hi all:
I just got 120 (GetLastError()) from GetCurrentDirectory() on WinME, that means the API doesn't implemented. Is there any other reason this call may fails? and any other substitute?
|
|

Are you sure GetLastError returned 120? The documentation says GetCurrentDirectory works on Windows ME too. Here[^] the link is. (See the requirements section there). Use FormatMessage and display your error right there.

Yes, I noticed the requirement section, and that was what make me wonder. I try to append the API with "::" but to no avail so far.
But I did see the two functions exported form Kernel32.dll from WinME:
GetCurrentDirectoryA and W

Can you please post the code?

TCHAR tszSetupDir[MAX_PATH] = {0};<br />
GetCurrentDirectory(MAX_PATH, tszSetupDir);
|
|
|
|

Note that if your project is unicode aware, then the unicode version of this function,
GetCurrentDirectoryW will be called. You will need MLU (Microsoft layer for unicode) installed on your Windows ME machine.
PS: If you don't care for unicode, you will have to make an explicit call to
GetCurrentDirectoryA

Exactly, GetCur...A works! Thanks a lot.

I would strongly suggest not to use ANSI version of a call in a unicode project. Install MLU and use the Unicode version. The major harm in getting it done this way is that if the path contains unicode characters, this call will fail again.
