Thank You! I find the error is the linker setting is not to be set the lib dependancy.

Where I can download spy++? I can't go to msdn because something is blocking my Internet Explorer from accessing any website related to microsoft. I'm using Visual C++ 2008 Express Edition
thanks for any question or answer

Hi,
Spy++ is distributed with all other versions of Visual Studio except the Express Edition. As far as I know its not available for free download. There are probably some good alternatives on the internet if you search.
You could however install a trial of a full version of Visual Studio 2008 [^] and Spy++ will be available in the installation.
Best Wishes,

But I have a nasty problem. I can't open any website related to microsoft or related to anti-virus. But I will download the trial version of Visual Studio 2008 via my mother's computer. Thanks

You might want to get a good anti-virus there.

About the trial version, it's too huge to download, and I don't have a fast internet connection, and I can only download 1GB of data per month.
|
|
|
|

Something that came up with a quick Google is this[^], which claims to be the "Compact equivalent of Spy++ with visual interface, versatile & easy to use"
Good luck.

I've been using the DeflateStream and the GZipStream for a while and recently I found out that both streams produced an excessive amount of data when compressing data.
Here is my question: Is there a bug in the compression algorythm?

ant-damage wrote: produced an excessive amount of data when compressing data
What are you compressing? The LZ77 algorithm can actually create MORE data depending on what your compressing.
ant-damage wrote: Is there a bug in the compression algorythm?
No.

I'm compressing a binary file. it is a 678KB file, and after compressing all bytes of it with DeflateStream I've got 1MB of data. I used the zlib compression library on the same file and I'v got a smaller file with 671KB.
I searched around the web and I found out that it's possible that the DeflateStream algorythm has a bug, and generates too much data compared with the original file data.

Did you mean compressing with GZipStream? Because... DeflateStream does not do compression.
ant-damage wrote: I searched around the web and I found out that it's possible that the DeflateStream algorythm has a bug, and generates too much data compared with the original file data.
The GZipStream class does not check for incompressible data. Yes it is possible to create more data.. this is the nature of the algorithm. I guess it would be better if the GZipStream class detected that it would be unable to compress the data. Classifying it as a bug is debatable.
I agree with you that the GZipStream class should be smart and detect this situation.
Best Wishes,

Yes it does, if we are to believe the documentation[^], compared to GZipStream it leaves out the CRC and things like that.

I have found that the results are better when you use the biggest possible Write (so buffer first, then write it all out at once). It's slower of course, but for some reason this implementation gives really poor results on small writes.
Such a big expansion seems excessive though. It can only happen due to crappy implementation, since the Deflate spec contains an escape mechanism to store uncompressed data with only tiny overhead, but then this implementation is not known for being good in any way.

Hi Guys this is my first post on the forum (Despite being a long time browser), i hope you can help me.
I am attempting to create and display a modeless form within some C++ code. It works fine when the form is displayed as a modal form using ShowDialog(). However when i use Show(), the form is displayed but with black spaces where the UI controls (Label and Button) should be. You can see that there should be something there but there isn't?
I'm guessing it may be somekind of threading issue? As in the main thread is attempting to create controls on a different thread?
Has anyone come across this issue before and if so how did they get around it?
Thanks

Hi,
whatever language you use, you shouldn't use multiple threads accessing controls on a single form; this[^] may be useful for you.

Hi Luc, thanks for the quick reply...
I'm aware that i shouldn't be using multiple threads to access controls on a single form, and as it stands i'm not intentionally doing this. My question is, is the modeless form being created in a new thread automatically (hence it's ability to return immediately from the call) and if so is this the reason why the controls aren't being displayed properly?
I've spent a fair while researching this and am not having much luck, i'm primarily a C#/.Net developer ans am having a little bit of difficulty with the C++ side of things at the moment.
Regards

A form is created in the thread that executes some kind of Form form=new Form(...) statement, and that is independent of how it will be shown (modally/modelessly) later on. So you look at the code and you'll know.

You did not show any code, you did mention threading. How can anyone but you answer that question?

I have the same question. When I Google I see .NET unit testing, and C++ unit testing, but I don't know if any of those will work for Managed C++. Anybody have success with a particular suite? (Hopefully open source)

Learnt what? We are not mind readers here.
What are you trying to test, your own program? If so then only you can decide what needs to be tested.

Hi,
In the strCommand I am having 2MB of Data and when i am trying to split with the new line it was throwing error.(to loop through all the data)
But it was working for minminum (ie 50 KB of datas like 0's and 1's).
How to over come this error? Very urgent.. Below is the code...
CString strCommand; // Holds 2MB of datas like 0's and 1's...
System::String* strDataReceived = "";
strDataReceived = strCommand;
__wchar_t split __gc[] = new __wchar_t __gc[1];
split [0] = '\n';
String *strSplitCommand[] = strDataReceived->Trim()->Split (split);
Please help..
Reg,
Subbu
