Got Tortoise SVN, downloaded the source set.
When compiling the Linking step fails... (see below)
My guess is my wxWidgets configuration/installation is messed up. 
I'll try again, any suggestions?
**NWNX4 GUI project seems to be missing(?)
Cheers

Do you have the Platform SDK set up and configured as described on the VS Express page (assuming that you are using Express) ?
MessageBoxA for example is a Win32 function.
The GUI project is missing, because it is not ready yet.

Your compilation may fail if you haven't disabled the Post-Build Event. To do this:
Right-click on each project, select Properties, select Configuration Properties, select Build Events, select Post-Build Event, and toggle Excluded From Build to yes.

No, I want the Post-Build Event, this copies the files to the 'dist' (distribution?) folder. This bit's working fine.
I've reinstalled C++Express, wxWidgets and vsSDK. Still the same issue.
Standard Windows calls (to libraries) are failing when called via wxWidgets libraries. I'm pretty sure this is a problem with my wxWidgets setup - was there anything special you tweaked when setting this up?
I've tried C++Express & Full VStudio2005 - both with the same results.

If this is still happening in a few hours, I can take a look -- but this sounds really familiar from another project I've worked on. Is there an option to enable/disable 'use default libraries' at the project level?

Hmm, since you mentioned wxWidgets: Did you compile the libs yourself ?
Because if you downloaded the libs\ directory from the repository, you already have what you need, and can skip the wxWidgets part.

Tried Both...
I had assumed you had all that was needed in the 'source' already.
That didn't work...
OK. Got it... at least something I can live with...for the moment...
Drive dependancy. 
Normally I have my work on my 'development' drive "D:\..."
--Installed everything on my 'test' machine to the "C:\" drive (and no problems)
Nothing I can see uses absolute file paths, but there must be something buried in wxWidgets somewhere.
So... here's a tip.
Export the source to a folder on your "C:\" drive - to avoid problems.
Cheers

That's strange indeed then...
--I'll investigate further... but I've got something that does work 
so I'm happy with that for the moment.

What steps did you take in order to solve the compilation problem ? I don't even know what platform you are using... a little more info would be helpful.
Also, there is a guide on making wxWidgets work with Visual Studio: http://www.wxwidgets.org/wiki/index.php/MSVC_.NET_Setup_Guide

| Posted: Sun Jan 14, 2007 9:15 Post subject: Trying to return a value... and the data encoding changes |
|
|
I'm writing a pluging based on sqlite3.
| Code: |
const char* PWData::DoRequest(char *gameObject, char* request, char* value)
{
wxLogTrace(TRACE_VERBOSE, wxT("* Plugin DoRequest(0x%x, %s, %s)"), gameObject, request, value);
<snip>
wxLogTrace(TRACE_VERBOSE, wxT("* Value found"));
size_t bytes = (size_t) sqlite3_column_bytes(sqlStatement, 0);
wxLogTrace(TRACE_VERBOSE, wxT("* "));
wxLogTrace(TRACE_VERBOSE, wxT("* Value Length = %d"), strlen(value));
wxLogTrace(TRACE_VERBOSE, wxT("* Value Size = %d"), sizeof(value));
wxLogTrace(TRACE_VERBOSE, wxT("* Value Data = %s"), value);
wxLogTrace(TRACE_VERBOSE, wxT("* Result Length = %d"), bytes);
const char* pCol = (const char*)sqlite3_column_text(sqlStatement, 0);
if (pCol)
{
nwnxcpy(value, pCol);
//nwnxcpy(value, pCol, bytes);
}
else
{
nwnxcpy(value, wxT(""));
}
wxLogTrace(TRACE_VERBOSE, wxT("* Value Length = %d"), strlen(value));
wxLogTrace(TRACE_VERBOSE, wxT("* Value Size = %d"), sizeof(value));
// wxLogTrace(TRACE_VERBOSE, wxT("* Value Data = %s"), value);
wxLogTrace(TRACE_VERBOSE, wxT("* ")); |
Trace: (TRACE_VERBOSE) * Value found
Trace: (TRACE_VERBOSE) *
Trace: (TRACE_VERBOSE) * Value Length = 1024
Trace: (TRACE_VERBOSE) * Value Size = 4
Trace: (TRACE_VERBOSE) * Value Data = ........................................(1024 of them)
Trace: (TRACE_VERBOSE) * Result Length = 32
Trace: (TRACE_VERBOSE) * Value Length = 4
Trace: (TRACE_VERBOSE) * Value Size = 4
Trace: (TRACE_VERBOSE) *
It's a pretty simple
my result is the correct size,
my value is a pointer(4bytes)
--when nwnxcpy executes it appears that it is copying the 4 bytes of the pointer into my value *not what I want.
Note: I've commented the 2nd Value Data.
This works the first time, but whenever I execute it after nwnxcpy() my entire application no longer recognises UTF8 encoding.
While I'm not proficient in C++, I'm a bit perplexed why a 'follow the example' bit of code is not working for me, let alone the weirdness of losing UTF8.
Any help getting sqlite3_column_text() and nwnxcpy() working together, they don't work together by default, would be much appreciated.
Cheers

What does wxLogMessage( value ) say? Scratch that.
This could be a problem:
| Code: |
void Plugin::nwnxcpy(char* buffer, const char* response, size_t len)
{
size_t size = strlen(buffer);
...
|
Instead of strlen( .. ), sizeof( .. ) perhaps? |
