PtrToStringAnsi or PtrToStringChars? Where are you calling PtrToStringChars?

Mark,
I was able to resolve this issue.
The command line:
crReportDocument->Load(L"C:\\QpayReports_CR10\\Batch.RPT",OpenReportMethod::OpenReportByTempCopy);
The frist argument to Load wascalling thr PtrToStringChars.
Solution:
As with other MS products, Look elsewhere for the error instead of where the compiler complains.
Thx Madhu.

hi every 1, this is my 1st post and i hope you guys can help me with my problem.
this is my problem .a quistion and i dont know how to solve it:
(Word Processing) One important function in word-processing systems is type justification—the alignment of words to
both the left and right margins of a page. This generates a professional-looking document that gives the appearance of being set in
type rather than prepared on a typewriter. Type justification can be accomplished on computer systems by inserting blank characters
between each of the words in a line so that the rightmost word aligns with the right margin.
Write a program that reads several lines of text and prints this text in type-justified format. Assume that the text is to be
printed on 8-1/2-inch-wide paper, and that one-inch margins are to be allowed on both the left and right sides of the printed page.
Assume that the computer prints 10 characters to the horizontal inch. Therefore, your program should print 6 1/2 inches of text, or
65 characters per line.

Here are the core problems with your question
1 - it's obviously your homework
2 - it obviously requires you to do this manually, which would not happen in the real world. If we told you the APIs for text justification, your teacher would fail you
3 - if your teacher saw this post, and a reply with code, he would fail you
4 - if someone were stupid enough to sit down and do your homework for you, when your teacher realises you have no idea how the code works, he would fail you
5 - if we did your homework for you, you wouldn't learn anything, and you'd have to ask us again. Eventually, we'd all get sick of doing your homework ( assuming that your teacher didn't spot in class that you have no idea about any of the work ), and he would fail you
6 - the odds are low that your course is being taught in C++/CLI, so the odds are low that you were even able to find the right forum.
Do your own homework. Ask specific qustions if, after trying to do your own homework, you get stuck. The question explains how to do it. All it doesn't say, is what language you are using ( which, I guess you know, although I'll be floored if it's C++/CLI ).

OK, so you're working through a book, and it doesn't have the answers in it ? I'd abandon the book for another one.
core99 wrote: the quistion is are you welling to help?
Really, what you're wanting help with is of no value, you can get any text to justify just by callnig the right API. If you're looking for learning exercises, I'd choose them from a book that gives you the answers, if you don't have a teacher to check your work.

Thats great Graus, its a good reply. But shall I say you one thing, Americans dont use better English than British. May be, I am wrong in your openion, but they some times use wrong grammer than Indians too. Dont mind this is just my friendly reply. Thank you.

I'm neither, but I agree, the reverse is true. Where did this come from ?
indian143 wrote: but they some times use wrong grammer than Indians too
Perhaps rarely. It's more often that Indian grammar and spelling is the worst. But, it's to be expected, as English is not their (your) first language.

Do you know a normal Indian can speak atleast 3- languages. My few Saudi(I was working there) friends got stunned when I said this. India has 30+ scripted languages and 2000+ unscripted languages. Ok. Thank you. Sorry for the inconvenience.

I guess there's some irony in the fact that (as far as I know) until now, no american has
posted in this thread.

I am afraid that I cannot speak or write well enough to reply!  However, it is apparent our Indian friends do not realize that there are several dialects of English. The correctness of one dialect over another is only determined by political and economic factors.

You need to ask questions that will elicite the answers you seek. If you have a specific question on a very specific issue, we can help. We are not here to read your mind or do your Google searches for you. Sounds like you need paid professional help!

this is my work:
#include<iostream>
#include<fstream>
#include<cstring>
using namespace std;
int main()
{
ifstream fin("data.txt",ios::in);
if(!fin)
{
cerr<<"could not open the file\n";
exit(1);
}
int nward=0;
int length[nward];
char word[nward];
while(fin>>word[nword])
nword++;
if(nward==60)
length[nword]=strlen(word[nward]);
while(!eof)
{
int done=0;
int wordcount=0;
int counter=0;
while(!done)
{
counter+=length[nward];
wordcount++;
if(counter==60)
{
counter-=length[nward]-1;
done=1;
}
still i need to work on this code "you can see that";
and its not complete i hope you guys can direct me,comment and help any way you like;

Many people come here looking for answers but don't know how to ask a question to elicit the desired response. If you are one of those people, please read: http://catb.org/~esr/faqs/smart-questions.html[^]
This does not apply 100% to this forum but there are some good points that can be applied here.

 Good link!
One thing I can't figure out... i get the "I know I'm just a pathetic newbie loser, but..." but
are "hackers" good or bad?

Since I am an old fart, I can remember when a hacker was a "good" guy. The definition of hacker has shifted a lot over the years unfortunately. The link below is about how the meaning of hacker has changed: http://en.wikipedia.org/wiki/Hacker_definition_controversy[^]

Hi
I want to use the DDEML library for dynamic data exchange with some arbitrary server, so I've written a small class that does this. The problem is that this class is written as unmanaged C++ but I want to take advantage of the nice .net CLI form environment so what are my options?
Can I make a library in unmanaged VC++ and use it in my CLI project ? Or what is the best/easiest solution? What do I need to think of?
Btw. I've already tried to make just that class unmanaged (no /clr) in the same project but that didn't work - should it (I get a lot of unresolved external symbols)?
Thanks for any input, feel free to be specific because this is my first CLI project

Add the native class to your main project, just like normal - no changes needed. You can then instantiate the native class and call its methods from your managed classes. Alternatively, you can integrate the functionality of the native class directly into a managed class. You can access the DDEML library just the same as you would from within a native class. That's what makes C++/CLI so cool for interop!

I thought so too. It compiles ok, but doesn't link. Seems it can't find the library, which should be internal?

Added the command lines..

Seems like I've fixed it by just adding the unmanaged C++ class file to the project. The CLI didn't find the libraries for some reason so I added them myself:
kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib
probably didn't need all of them, but what the heck?

can we connect database through c and c++. if yes means how. if not why
s.pradeeba

|

yes.
Is this your question meant to c++/cli or Managed c++? If not you are in the wrong forum.
You are letting out some info:
What kind of database? (MySQL, MSSQL...)

|
|

Have you heard of google ? If not, why not ? If so, why didn't you search for this information yourself ?
Is this question about .NET programming ? If not, why is it here ? If so, how do you expect to use C in .NET ?
ADO and ODBC are two good starting terms for your google search.
