[↓] [vPodans] # short notation of this error: [↓] [vPodans] Get-ErrorMessage 5 Access is denied. Even though the script won't handle any Win32 errors, but, most of them — definitely and this function will be included as a part of my upcoming PowerShell PKI module update.

This is the version of ErrorString I used in a network-based application. My original assumption was that any code that is listed on this page can be converted to a description using FormatMessage as a system message. Error code short (low bytes) part. Although, I'd disagree with your both approaches, ovidiucucu, proposed in your last post. 1.

It tells what the application-level error is, what file was being considered, and the description of the error code. When the error is something that needs to be displayed to the user, you can use my ErrorString function to get a nice CString. Today's topic is described in the post header :) I guess most of you have encountered with some application/system issues. In fact I was going to suggest writing an error handling class with a static method that was pulled out into a common library to do this sort of thing.

However if he does, he may notice that testing for range INTERNET_ERROR_BASE to INTERNET_ERROR_LAST before calling FormatMessageFromHMODULE doesn't save too many CPU cycles since most of errors will be WinInet errors For example void CSampleApplication::Lookup(const CString & name) { LPMYINFORMATION Somevalue; ...do some computation...

This is at best useless and at worst harmful. This is rarely, if ever, of value, and as far as I can tell, having worked in three other major operating systems that supported a FormatMessage equivalent, this seems to arise But to sneak this by the compiler, an explicit (LPCVOID) cast must be written. [19] This is the 32-bit error code that will be checked against the error table(s). [20] This However, this function additionally can produce text messages for network errors.

Just for your information, if you want to get the error text while debugging, place in the watch window of the debugger the request @ERR,hr This is a screen snapshot of WINHTTP.DLL also works and returns exact same error descriptions. Originally Posted by ahmd 2. For that matter, what file?

Also WinHttp error messages are located in WINHTTP.DLL and not WININET.DLL. check over here While I called a WinHttp before, GetModueHandle("winhttp.dll") will work and Commander Data will be even more happy because of saved CPU cycles. Perhaps you did not expect this error and don't really know what to do when it occurs, but your tech support people could waste hours trying to track down a problem we have called a WinInet function, so wininet.dll is already loaded).

Arjay, maybe you can write a static FormatMesageEx function that handles all system error codes from that page above? Do not optimize 2. Don't know why...

The reason I started using LoadLibrary instead of GetModuleHandle is because the latter didn't work for me.

I also would not be worried about the overhead of an additional function call. Originally Posted by ahmd 1. I'm sure there'll be many people who can benefit from it in their code. Even some error codes/messages are the same, there is not guaranteed that all are the same.

I missed it. Not the answer you're looking for? Does profunda also mean philosophically deep? http://discusswire.com/wininet-error/wininet-error-997.html This is a simpler implementation than the code for WinSock, because the WinINet module is already loaded.

The API call will allocate the buffer, and store the pointer to this buffer in the location pointed to by this parameter. In this case, we revert to formatting a simple string. [22] Due to what is poor design, every message gets a \r\n (CRLF) appended to the end of the message. The file cannot be opened. You got it!

I was expecting something like ERROR_INTERNET_DISCONNECTED. share|improve this answer edited Aug 12 '13 at 8:09 Cody Gray 147k23279371 answered Jan 29 '10 at 2:22 Shog9♦ 109k28184217 1 wow didn't know this! –Matt Joiner Jan 29 '10 Related 0Why is wparam changing if i use same message, with same paras?0Adding to HIMageList failing, cannot figure out why1Why WinAPI FormatMessage fails, always returns false0C++ WinINet FtpPutFile Error 120031WinInet request I don't understand why do we have to write something that must have been implemented by the makers of the OS a long time ago, but nonetheless...

However, do not remove the FORMAT_MESSAGE_IGNORE_INSERTS flag. Hopefully my script resolves this limitation by adding a reference to the wininet.dll library when it is necessary. The time now is 06:16 PM. In the cases of component specific errors (like the wininet error), you'll need to consult the component documentation.

Your tech support people will be greatly aided. Yesterday I wrote a PowerShell script that will convert Win32 error code to a readable text. I verified this by using the dumpbin utility on WSOCK32.DLL, and got the following: Microsoft (R) COFF/PE Dumper Version 8.00.50727.42 Copyright (C) Microsoft Corporation. Note that even if you think the message code is of no use to the user, display it anyway.

So it must, when that flag is specified, by a pointer-to-an-LPTSTR, and to sneak this past the compiler, the explicit (LPTSTR) cast is required.

Here is a known limitation, this function doesn't handle network-related errors (that are defined in wininet.h header file).
