Yes，there isn't MSJAVA.DLL in my PC. I place MSVCR80D.DLL in the folder where the target DLL exist, dependens report error opening file(MSJAVA.DLL). How can I resolved this problem when using VS2005.My DLL can't be load both in Release and in Debug.

Hi all,
Just trying to hardcode a file path into a CString variable but result ignores backslash (I believe it may be interpreted as control character?).
e.x.
CString Path;
Path = "..\dir1\dir2\filename.ext";
result for path is "..dir1dir2filename.ext"
Also, another nagging string issue I have never understood is a compile error I get when I try to concatenate string literals -
Path = "abcd" + "abcd"; //causes a compile error, "cannot add 2 pointers
My compiler (VS 2005) is set to use Multi-Byte Character Set.
I once tried to research unicode v.s. Multi-Byte Character Set and I could not make heads or tails of the significance.
Thanks for any tips.

'\' must be escaped (repeated since it is the escape character) in a string literal, change to
Path = "..\\dir1\\dir2\\filename.ext";
al2500 wrote: Path = "abcd" + "abcd";
'+' is not the concatenation operator for string literals, you should change it to:
Path = "abcd" "abcd";
or
Path = "abcd";
Path += "abcd";
or
Path = CString("abcd") + CString("abcd");

Well, you should ask MS to change the documentation [^], [^] and, above all, persuade the compiler of ...

Apologies, you are, or should be, right. I really need to stay away from MFC questions.

Thanks guys,
I also realized that hardcoding a path(even relative) is stupid and in fact I could not get it to work. I found the following superior method that I had used elsewhere-
char acPath[256];
if ( GetModuleFileName( NULL, acPath, 256 ) != 0) {
* ( strrchr( acPath, '\\' ) + 1 ) = '\0';
}

Unicode is usually a 16-bit (sometimes 32-bit) encoding of a character set. Multi-byte character sets (e.g. UTF-8) are encodings where each character is represented by one or more bytes. In each character the left most bit(s) of the first byte indicate how many bytes make up each character. In the ASCII set of characters in the range 0x00 to 0x7F each character is one byte long. There is some useful (and well explained) information here[^].

Hi:
I am migrating from VS 6.0 to VS 2008 and I am stuck on this error.
error C2679: binary '>>' : no operator found which takes a right-hand operand of type 'const char [13]' (or there is no acceptable conversion)
It is occurring here:
istream & operator>>(istream &stream,IOwnship &object)
{
//## begin IOwnship::operator>>%.body preserve=yes
char tempStr[80]={0};
UINT16 temp16;
stream >> (ISimObj&)object;
int i;
for( i=0; i<IOwnship::NUM_EXPENDABLE_SLOTS; ++i){
stream >> object.m_expCount[i] >> temp16;
object.m_expType[i] = (ExpendableType)temp16;
}
stream >> temp16; object.m_fuelType = (FuelType)temp16;
for(i=0; i<NUM_FUEL_TANK_TYPES; ++i){
stream >> object.m_fuelQty[i];
}
UINT32 malfID;
UINT16 malfStatus;
UINT16 moreMalfs;
stream >> "Malfunctions";
for(stream >> moreMalfs; moreMalfs; stream >> moreMalfs){
stream >> malfID >> malfStatus;
object.m_malfStatusMap[malfID] = MalfStatusActType(malfStatus);
}
I have included:
#include <iostream>
using namespace std;
This works fine in VS 6.0.. any help would be greatly appreciated

You are trying to read from stream into a constant, I don't think this will work; and even if it did it would serve no purpose.

I am programming a console application that plays .wav files. I have set the members of the WAVEFORMATEX to the values of the read file. As a try, I set the lpData member of the WAVEHDR member to the buffer where the file was read into and the dwBufferLength to the size of the file. I have also prepared the WAVEHDR structure. This plays the file when I call the Sleep function for some seconds (Not the best approach) after calling waveOutWrite. I have read that files should be played using double buffering approach but I don't know how this is implemented. I used a callback function in the waveOutWrite function and I am also able to trap WOM_DONE and WOM_OPEN messages.
Please I need help on how this double buffering sheme is implemented. I have read that when one buffer is being sent, the other is being prepared but I don't know how to do this. Some tutorials may help to get the idea.
Please help me.

Hi
Is it possible to use Google Map in a MFC application? I want to read in the roadway map (traffic network) data.
Is there a sample for it?
Thanks,
Zhen

I don't think so, but read here just in case.

I have seen an MFC application that uses Google Map to load roadway map into the application's window. The program is a custom made highway information system. That means it is possible to do it. However, I don't have access to that program, therefore, I can't show you how they did it.

Could you tell me a little more about the highway information system? like any information related to it. Name? web pages?
Thank you so much,

I guess you could always embed a web browser control in your MFC application and navigate it to Google maps

Hey guys, i am having problem in putting the str i want to search for using find().
I have a text file which hold data like this :
"ewcwecwcdwecwewewe"<eddwdwwee>""d"dsdad"d""dd ewfewfwe"wewe"
What the problem is , i want it to search for "d". the issue is , when i put it into the code below
string.find( ""d"dsdad"d"" , 0) ;
what happens is that , it is unable to read the variable to search for properly as it contains "" also.
thus, it will just "dsdad and miss out the d and ".
what can i do to solve this problem?

I don't konw if you meant this.
But try \" for every quote you need to search for.
Example:
string.find( "\"\"d\"dsdad\"d\"\"" , 0) ;
Should find ""d"dsdad"d"" in the string.
Greetings

The outline of the problem:
I have an exe which will be displaying the status of various pieces of remote equipment in the form of icons and screens.
The remote equipment is NOT defined at this stage so I want a DLL which I can NAME in a setup file, load, and which has a standard interface to my main exe. The interface (at the moment) is 'load', 'giveMeStatusIcon', 'updateStatus' (largely so I can force the change of the status icon), 'showStatusScreen'
The basics of loading a DLL from a name, getting the interface, calling the functions above all work. I can on my 'exe' screen show the returned status icons - these icons are resources in the dll and returned as icons for my exe to display
The problem comes when I ask it to show the status screen. This screen is defined in the DLL resource, and thats the way I want it - I don't want my exe to have to worry about what is in that DLL screen, what it does or how it does it. The DLL gets called, loads the dialog resource ok, but the DoModal call causes an assert - the DLL is not a CWinApp so DoModal can't apparently work.
I guess one possible way is to stop creating a DLL and create an EXE, start that and setup some inter process comms to deal with the communication. But I would much rather stick to the plan of using a DLL.
Does anyone have any suggestions?
Note I do NOT want to write all possible remote device DLL's now and start putting .h files in my exe, I want to stick to the basic idea of having these as items I can develop next month, next year, or whenever and use frmo my exe via loading of a dll file with a fixed API (at least to my exe) at run time.

What is the assert you get, and why are you calling DoModal() on something that won't handle it? Assuming your DLL is pure Win32 then you should be able to do this without any problems using the DialogBox()[^] function.
