[Dev-C++] help needed with calling dll from Visual basic

[Ni J. <ni_...@ba...>]

Hi, All.

=20

I am writing to ask for help from the Dev-C++ user community with the
problem of calling dll from visual basic.

=20

I wrote a dll by using Dev-C++ and the dll works fine with an interface
written in Dev-C++.  However, when I tried to call the dll from an =
interface
written in visual basic, I run into problem.

=20

1.	The dll contains a function with prototype shown below. It
concatenates the time to the string "name".

=20

Void reportTime (char *name);

=20

            I call the function in dll from visual basic by using the
following declare statement

=20

            Private Declare Sub reportTime Lib =
"c:\dlltest-4\dlltest-4.dll"
(ByVal name As String)

=20

            I get an error message "bad dll calling convention". =20

=20

2.	So I made some change to the prototype of the function in dll by
adding _stdcall as shown below.

=20

Void _stdcall reportTime (char *name);

=20

The declare statement is the same in the visual basic interface.

=20

This time, I do not get the error message shown above and I can tell =
that
the string "name" is passed into dll and the function can concatenate =
the
time to the string. However, after the dll returns the control back to =
the
interface, the string "name" in the interface does not reflect the
manipulation done in dll.  I do not know what to do.=20

=20

Thank you in advance for your time and help.

[Dev-C++] compile problems

[Noorez K. <dar...@ho...>]

When I tried to put all the parts for my library one directory deeper, the 
compile process didn't work! It froze while linking the static library

Thanks for reply.
I tried it. DevPak which can be downloaded by Package Manager is little 
old (DirectX was updated last time in october). What is more there is 
used the same trick with d3dx9d.lib and d3dx9d.dll (d3dx9.lib is absent).
Because it is out of date I hoped that this problem was resoled in meantime.

VS: [Dev-C++] GLUI x DEV-C++

[Petri K. <ke...@we...>]

Have you get the glui.h from here: http://devpaks.org/index.php ? (OpenGL
dir)

There they are in devpack formats (Tools/Package manager etc..)

I put glui, opengui and freeglut devpacks.

But then...even though there is glui.h the test program seem to need
<gl/gl.h>

Do you have that gl.h ?

Re: [Dev-C++] Strange compilation unit errors

[Scott S. <ssi...@sp...>]

Thank you for all the help. I added the return type, changed height to 
height_, and in a few places, changed a -> to a . I then had to do one 
cast, and now everything works fine so far. Thank you for your help.

Thank you for all the help.

Exactly. If you open the Dev-C++ help, go to Getting Help -> FAQ, and 
try to copy/paste the code, you'll have this problem.

Re: [Dev-C++] Strange compilation unit errors

[Per W. <pw...@ia...>]

First of all, you forgot to specify bool as return type for the LoadTGA()
member function.

Then you have also misspelled the some property fields 'height' instead of
'height_' for example.

One can try out Programmers-Town yahoogroups..It's sort of ok group with
not so high(approx-200-300 mails per month) traffic...

Hi All!
Do You know high traffic c/c++ mailing lists?
(IDE related, or ANSI, whatever)
I've subscribed a lot of lists, but I'm getting more mailing list
reminders, than any small idea of programming...
I've tried google, but methink it is much easier to create a list, than
to find a working one.
So the net is full of nonworking or _very_ low traffic lists.
You may send your tips in private, I will post my collection to the
dev-cpp list, if anyone interested...

Thank You,
Tibor

In the past I've discovered that copying and pasting source from web =
pages or other non-plain text electronic documents can result in the =
inclusion of non-printing characters.  Not sure if fred copied and =
pasted, but I'd guess that if he started with a clean file and typed in =
the code the errors would go away.

Re: [Dev-C++] mailing lists

[Per W. <pw...@ia...>]

The net is full of nonworking or _very_ low traffic lists because a lot of
people is doing exactly what you do: Creating a new list.

Most high-volume places aren't actually mailing lists but are either news
groups or web forums. They have so much traffic that you normally don't
want all posts sent out as mails.

Re: [Dev-C++] symbol unsure

[Per W. <pw...@ia...>]

Octal specification works fine, but more often hexadecimal is more
intuitive, i.e. "\x40" for '@'.

What was the question about the = operator?

using c strings, = assigns the pointer to a string, to the actual string
contents. Using the std::string data type on the lefthand side, = assigns
a new c string to the c++ object, i.e. calls the operator= method for the
std::string class object.

This is the syntax to write ASCII characters directy inside a string.
E.g. \097 should be equal to 'a'

But how can you use the = operator to Strings in Cpp?

I just copied both of the code samples that you gave and pasted them 
both into Dev-C++.  They both compiled and ran just fine.

However, the error message you're getting makes it sound like you've 
got a stray ascii character in the text file. Octal 204 is the =E4 
character (if that came across.)  I don't see that character in the 
examples you listed.  Are you sure the code samples are exactly what 
you're trying to compile?

Re: [Dev-C++] Window closes after Run

[fred m. <man...@ya...>]

Hello ,
This is a follow up with respect to my question about the execution window which closes after Run.
 
First, I am using Dev C++ (4.9.9.0) and I have Windows XP.
 
When I use :
 
#include <stdio.h>
int main(int argc, char **argv)
{
  printf ("Press ENTER to continue.\n");
  getchar (); /* wait for input */
  return 0;
} 
 
OR
 
#include <stdlib.h>
int main(int argc, char **argv)
{
  system ("pause"); /* execute M$-DOS' pause command */
  return 0;
} 
 
 
I get error messages (6 for the first and 4 for the second) which are : 
stray' \204' in program.
 
these messages are after the following :
in function ' int main(int,char**)'  which is not assigned as error.
 
thanks.

[Dev-C++] Window closes after Run

[fred m. <man...@ya...>]

Hello,

I have a problem related to the execution window (the Dos prompt window). When I run a program after compiling it, the Dos window appears for a milisecond and then it's gone. I have tried what is said in FAQ which is :

 // Q:  My window keeps closing, how do I change that ?

 // A:    You can do it this way: 

// #include <stdio.h>

// int main(int argc, char **argv)
// {
//    printf ("Press ENTER to continue.\n");
//     getchar (); /* wait for input */
//  return 0;
//  }

 //  Or this way: 

//   #include <stdlib.h>

//   int main(int argc, char **argv)
//  {
//  system ("pause"); /* execute M$-DOS' pause command */
//  return 0;
// } 

But I got error messages with "printf" or with "system".

Can you help me?

I didn't have time to hand-edit the Makefile, so here is the .dev file I

the project type to static lib.
