I've trying to google a little bit but didn't find an explanation for the above error.

Hi David.

Thanks for your help,but this warning is not my problem...
I know that my problem is the errors below(LNK2001)...I just can't find the call for invalid_parameter_noinfo.
According to MSDN(relating LNK2001):

When compiling with /MD, a reference to "func" in your source becomes a reference "__imp__func" in the object since all the run-time is now held within a DLL. If you try to link with the static libraries LIBC.lib or LIBCMT.lib, you will get LNK2001 on __imp__func. If you try to link with MSVCxx.lib when compiling without /MD you will not always get LNK2001, but you will likely have other problems.

All the libraries in the solution,as well as the executable, are being compiled with /Md option(i.e runtime library is a multhi-threaded DLL).
In the linker option I specified the linker to ignore LIBC,LIBCMT and MSVCRT default libraries.
But still,I get those error...

Anything?

Thanks again,
Best regards,
Eli

Hi David,

I removed MSVCRT.lib from default libraries ignore list and it's working just fine.

Thanks again,
Eli

This explains the fact.

error LNK2019: unresolved external symbol __imp___invalid_parameter_noinfo

This means program calls invalid_parameter_noinfo() but no symbols around libraries.
If you did not call this function directly, some libraries (guess MFC?) call it.
You can try goole with keyword by invalid_parameter_noinfo.

Creating bitmap from scratch using GDI and convert to raw memory data

GingkoBiloba3-Jun-09 3:37

Hello,

Please could somebody help me about the following :

I need a simple way to create a bitmap from scratch in memory, draw something in it using some GDI functions (like LineTo, Polyline or TextOut), and convert the result in a 2D byte array, for using in a home made raster device.

The result needs to have only 2 colors (black and white), although it can be useful to have intermediary grayscale in order to be able to stretch or shrink the bitmap and choose the transition level between black and white.

No file nor any resource nor any window should be involved, everything has to stay in memory. No compression is needed either.

Language is C/C++, *without* MFC.

I tried using CreateCompatibleDC, CreateCompatibleBitmap and GetDIBits, maybe this is still what I have to do, but now unfortunately I get only inconsistent results.

Is there somebody here who already made something like this ?
Best regards,

Gilles

C++ MySQL Column Names

Hi Guys

I have a problem which has got me beat and would appreciate any help in either finding a solution or even a 'pointer' to a solution.

The problem is I tend to use a lot of MySQL for various jobs. Normally I would use either PERL or PHP to acces the database and both do a grand job. More recently dusting off my C++ skills I decided to approach the MySQL from a C++ angle. Now I can connect to a MySQL DAtabase, run a query and retreive the data from the query results. What I would like to do is to get Meta data about the fields from the query. Name, datatype that sort of thing. Now this is easy in PERL or PHP but I've tried several methods with c++ and to date no success. What I have found is poorly documented and without the correct parameters the whole thing goes nowhere
There is no specific reason for needing this and no urgency just I would like to see if it can be done. Any help will be warmly appreciated.

Thanks in advance

It would probably help you to know the units that 'date_time' represents - is 1243930978 the number of seconds from some epoch? Or what? Do you know?

Oh - and as I've suggested to you before - post to the correct forum, where they know about Managed C++/CLI
