Hi
I wan't to be able to get a filetypes icon, preferably the position in the system image list, and the description string. Is there any API for this?
OBS! I know that I can use SHGetFileInfo, but then I must supply filename. I need it on extension basis.
I prefer to be anonymous.

I think you can still use the SHGetFileInfo, but you have to specify the GFI_USEFILEATTRIBUTES flag in the uFlags argument, this way the function does not access the specified file, so you can pass a bogus file name with the extension you want.
If this does not work, you can still look for all the informations you want in the registry......
Good luck!

Thanks a lot! It worked perfectly except for the icons for directories!

My app uses Shlwapi.dll which I would like to include with my installer.
I understand this is part of IE.
Is there a redistributable IE I can include with my installer incase the user does not have this DLL?

I think with things like this, you must redistribute IE.
Yes, you are groaning with the displeasure of it all.
Seems that that is the way MS like it. A damn good way of
ensuring that everyong has IE on their machine

Thought as much 
So, where do I get hold of a redistributable IE setup file for inclusion on my CD?
I cannot find a full version for download anymore - only a setup which downloads components from the net.
I need a full self contained setup for IE.
Also, anybody know of any legal issues which apply inorder to redist IE?

Have downloaded the full version of IE many times but not for a while so my memory is sketchy. I can't remember exact button names but think I can fudge my way through.
When you download the setup.exe stay connected to the Internet, run setup.exe. Click your way past the force agreement section, you should then be presented with a screen with the choices of Minimal or Typical installation (mutually exclusive Radio Buttons). Select Minimal (as this is also custom) click Next, on this screen select everything (or what is required) BUT before clicking Next look for another button on the screen (I think at the top). This is something to do with associations or some crap, in the ensuing dialog select download only don't install (something like that) and sit back and relax as it is a ~60 MB download.
I have a fattish pipe to the net at work, if by extreme chance you happen to be in the Sydney Australia area send me an e-mail I can download it for you and burn it to CD.

Thanks... Serves me right for not reading the install options fully!
You are right, choosing minimal allows you access to an advanced section which provides support to download rather than install. Perfect, thanks.
Still don't understand why MS couldn't just let you download the full thing directly like you used to be able to!
Oh well, thanks for your kind offer of the download BTW but I'm in the UK. Fortunately we have ISDN-128 at work so I guess their phonebill will just have to take a small hammering
Who knows, it might encourage them to get ADSL installed!

Hi
I'm using the WriteFile and ReadFile WINAPI to write/read from a COM port periodically.
The protocol is : first wirte to a port and then read the response from a port (=device). The write operation occures every 50 msec at least.
Every second attempt to call WriteFile fails and GetLastError returns ERROR_OPERATION_ABORTED. Then I use PurgeComm to clean a port after the failure. The next call to WriteFile succeedes, ReadFile succeedes, and the next try to write is cancelled and so on.
Does anybody know what can cause this error?
Thanks
Natalie

I don't have a direct answer as to the cause, but you might want to look into overlapped IO in a situation like this - creating a file with FILE_FLAG_OVERLAPPED allows simultaneous reads and writes, and gives you a more windows like async type of operation.
Takes a little more work to set up - there's good stuff on codeproject to help - (pj naughter's class may use this approach, or both - not sure) - but once you get it going its nice - polling is soooo passe...
And don't be scared by the docs - overlapped io is available for COM devices on win9x.
Just a thought.

Hi all,
I'm using ADO for accessing a MS Access database file in a DLL. I then use this DLL in my application. The problem happens when I try to start any NT service (for ex, IIS Admin Service) and my application at the same time: my application seems to hang forever. I put some debug logging and find out that it get stuck in a function _RecordsetPtr->Open(...), I then try to use _ConnectionPtr instead, it also get stuck in _ConnectionPtr->Open(...). I am very confused and I don't know what's going on. Have anyone encountered this problem before? Please help.
Thank a lot,
Rocky

I'm looking for a way to create a texture using a .tif file in DX8. Jpgs and bmps are no problem, but I need the alpha component of a .tif file. I tried using the D3DXCreateTextureFromFileEx() function, but I can't seem to get it to work properly.
Any help is appreciated,

Hi,
I would like to know if there is a limit number of transactions we can do when using DDE by including <ddeml.h>.
I am writing an application to read cells from Excel. This application will read more than 20.000 cells in a spreadsheet. The application starts working well, but after reading about 2000 cells, it crashes and I need to restart the computer because nothing works anymore.
The application is a dialog based app and works like this:
DdeInitialize(&idInst, (PFNCALLBACK)&DdeCallback, hInstance),
APPCMD_CLIENTONLY, 0);
//Setup HSZs for Service and Topic
hszService = DdeCreateStringHandle(idInst, szServerApp, CP_WINANSI);
hszTopic = DdeCreateStringHandle(idInst, szTopic, CP_WINANSI);
//Connect to server app
srvHndl = DdeConnect(idInst, hszService, hszTopic, NULL);
if(srvHndl == 0L) {
AfxMessageBox("ERROR", MB_OK|MB_ICONSTOP);
return;
}
else
{
//. . .
// This code is inside a loop that will get the cells
strcpy(szSendStr, "R");
strcat(szSendStr, lineNo);
strcat(szSendStr, "C1");
testData = DdeCreateStringHandle(idInst, szSendStr, CP_WINANSI);
retData = DdeClientTransaction(NULL, 0, srvHndl, testData, CF_TEXT, XTYP_REQUEST, 5000, NULL);
retD = (LPTSTR)DdeAccessData(retData, NULL);
DdeUnaccessData(retData);
DdeFreeStringHandle(idInst, testData);
//. . .
}
DdeUninitialize(idInst);
Thanks a lot for any help

Hello,
Im new to Programing, this maybe a dumb problem but Im beating my head aginst the wall.. I am trying to nest quotes into a string.. this is what I have tried..
CString strServerName;
CString strRemoteExecute;
strServerName = m_strServerList;
strRemoteExecute = """Remote Execute""";
if (m_bRemoteExec == TRUE)
WinExec("wviewnt -t"+strServerName+" -c"+strRemoteExecute,SW_SHOW);
From a command line to execute the wviewnt.exe you need to use quotes around the command, for example:
wviewnt.exe -tServerName -c"Remote Execute"
Any help would be appreciated..
Thanks

I'm afraid that this just won't work, as you have found. To input special characters into a string, the character \ is used. This bit me a fair bit when I first started, because I always forgot that to put one slash into a string I needed to put two (\\). The first tells the compiler that you're about to specify a character that is otherwise unavailable, and the \ is unavailable because it is in charge of this task. So to put a new line into a string, to for example put two lines into an AfxMessageBox, it's \n\r ( newline/return combination ). And to put in quotes, it \"
Like this:
CString s = "\"this is a quote\"";
AfxMessageBox(s);
