问题 Here's my scenario: I have a program which produces debug output with OutputDebugString() which maybe contains messages indicating bugs. I want to run this program inside daily build and automatically listen to debug output, parse it and report suspicious output. There're several examples of such listener implementations, for example this one. They all do the same - listen to a system-wide event and then read data from a file mapping. The problem is this protocol allows for only one instance

Is there a Unicode alternative to OutputDebugString?

问题 OutputDebugString() is native ASCII, which means it convert the input Unicode string to local string before call the ASCII version OutputDebugStringA() . Is there any alternative to OutputDebugString() which supports Unicode? 回答1: OutputDebugStringW does internally call OutputDebugStringA , so Unicode characters that cannot be represented in the system code page will be replaced with ? . Oddly enough, the OUTPUT_DEBUG_STRING_INFO structure the debugger receives from the operating system to

问题 This has happened to me on more than one occasion and has led to many lost hours chasing a ghost. As typical, when I am debugging some really difficult timing-related code I start adding tons of OutputDebugString() calls, so I can get a good picture of the sequence of related operations. The problem is, the Delphi 6 IDE seems to be able to only handle that situation for so long. I'll use a concrete example I just went through to avoid generalities (as much as possible). I spent several days

问题 Is there an NSLog declaration in the Delphi OSX units. I failed to find a substitude for OutputDebugString in a Firemonkey application. The final solution looks like this: /// <remarks> /// Output debug string. Output debug string can be seen in Delphi /// View|Debug Windows|Event Log or with 3-rd party programs such as /// dbgview.exe from SysInternals (www.sysinternals.com) /// </remarks> procedure ODS(const Text: string); begin {$IFDEF MACOS} // http://stackoverflow.com/questions/12405447

Bypass OutputDebugString in Delphi 7?

由 亡梦爱人 提交于 2019-12-20 00:00:43
问题 I'm wondering if it's possible to bypass the OutputDebugString? I'd like the OutputDebugString output showing up in DebugView and not in the internal Delphi Event Viewer window. But i can't find a way to tell Delphi not to swallow the OutputDebugString. Any ideas? regards 回答1: That is not possible. OutputDebugString sends string to debugger (as its name suggests). There can be only 1 active debugger per process. You run your application under Delphi - Delphi got the messages, since its a

问题 I've some "rogue" OutputDebugString call in my application which prints out "T", but I can't just locate it. Is it possible somehow to set breakpoint on OutputDebugString -function and see where it is called from? I'm using Delphi 2009. 回答1: How many calls to OutputDebugString are there in your project? You can use the "Find in Files" dialog to find them all, and if they aren't too many, there shouldn't be a problem. Otherwise, you could - of course - use a search and replace and replace all

How can I receive OutputDebugString from a service?

由 ↘锁芯ラ 提交于 2019-11-29 09:26:50
I'm trying to catch all OutputDebugString messages (including those from services) using the following code. It worked fine until I migrated to Windows 7. The problem is that since Windows Vista services are running in the low level Session #0, some people say that it's impossible to catch them and some that it is. What do you think? Is it possible to modify the following code by increasing some rights to be able to receive OutputDebugString messages from the Session #0? In other words; is it possible to share DBWIN_BUFFER in the session #0 with Session #1? I would say it should be possible

How to view output of OutputDebugString?

由 谁都会走 提交于 2019-11-28 08:34:39
I want to use OutputDebugString() in my application and then have the option to show it in a separate viewer when the application is deployed in the field. That is to say, I don't want to have to change a flag and rebuild my .exe to turn debugging on and off. Googling around, it seems like DebugView should handle that, but neither it, nor TraceTool show any output from this code. unit Unit1; interface uses Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics, Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls; type TForm1 = class(TForm) procedure
