[Dev-C++] ado and database access

[Derek C. <der...@ho...>]

Hi

I have just started using dev c++ v4.98 and am experiencing problems 
connecting via ado to an access database using code that previously worked 
under visual studio 6.

The code I have used previously is:

#import "c:\program files\common files\system\ado\msado15.dll" \
// This code comes from : www.geocities.com/mokarrabin
#include <stdio.h>
#include <windows.h>
#include <iostream>


using namespace std;

int memscan(void)

{
    int istopped =1001;
	int flagged=1001;
	CoInitialize(NULL);
	char storeVal[100];
    try
        {
        _RecordsetPtr pRst("ADODB.Recordset");
        // Connection String
        _bstr_t strCnn("DRIVER={Microsoft Access Driver 
(*.mdb)};UID=admin;DBQ=data.mdb");
        	 // Open table
        	pRst->Open("SELECT * FROM tblProg", strCnn, adOpenStatic, 
adLockReadOnly, adCmdText);

        	 pRst->MoveFirst();


            	 while (!pRst->EOF) {




		          strcpy (storeVal,(char*) ((_bstr_t) 
pRst->GetFields()->GetItem("prog_process")->GetValue()));




					 pRst->MoveNext();
            	 }
            	 pRst->Close();

        }
        catch (_com_error &e)


            {
            filewrite((char*) e.Description());
        }
        ::CoUninitialize();
		return 0;
    }

This however generates to many warning and refuses to compile.
Any alternative ideas would be appreciated.

Regards

Derek

I'm reposting this to the list as I'm unsure...does it compile when not 
going for win32 ?

Re: [Dev-C++] WinMain@16 linker error, help needed

[Daniel G. <sp...@ho...>]

WinMain error? you need a winmain function, the entry point to your program, 
do you have that?

WinMain parameters are ifferent I think.

[Dev-C++] WinMain@16 linker error, help needed

[NBarnes <nw_...@ya...>]

 Hello, all,

 I am having some trouble getting Dev-C++ working to compile my current
project.  The compile goes fine, but I get one linker error that reads:

C:/DEV-CPP/lib/libmingw32.a(main.o)(.text+0x7f):main.c: undefined
reference to `WinMain@16'

 There are several references to errors like this one that I've found
through Google, including several useful looking ones at:

 http://cygwin.com/faq/faq_4.html#SEC92
 http://www.cygwin.com/ml/cygwin/2001-01/msg00612.html
 http://www.bloodshed.net/dev/faq.html#winmain
 http://sources.redhat.com/ml/cygwin/1999-05/msg00352.html

 However, none of these links quite speak to my problem.  Several
refer to adding a main() function to my program, but I already have a
int main(int argc, char *argv[]) {} function, and adding a int main()
function doesn't seem to help.

 One of the other major solutions involves tweaking one's linker
command line options.  How does one do this in Dev-C++ 4.9.7.8?  The
screenshot shown in the help file for the Project Options box does not
correspond to what I see in 4.9.7.8, as my version doesn't have an
text box where I can change the linker options.

 In short, I'm confused and could use some help.  Thanks to anybody
that can take a few minutes to give me a hand.

                                                         NBarnes

[Dev-C++] Trying to be the Devel

[Eugene K. <erk...@ho...>]

Hi evry1
Can any1 plz point me in th direction of sum downloadable source projects 
such as th 1's in the Dev-C++ Examples folder?

Iv found the study of them to b far more educational than any books or tut's 
iv read. i.e. you can change stuff, recompile, && see wot happens.

Iv also found 'sniplets' very handy but outdated. are there any other 
libraries you cood recomend?

Thanx & happy easter.

Eugene

Re: [Dev-C++] custom toolbar

[vitamin <vit...@nc...>]

If you want to show your bitmaps in your toolbar button
NOT use CreateToolbarEx() function
and NOT use SendMessage(hToolbar,TB_ADDBITMAP,(WPARAM)3,(LPARAM)&tbab);
ONLY standard toolbar buttons can normal execute.

I tried many times, and got no error, no warning, and only close
application.
I think that the commctrl.a maybe is old.

Only imagelist can run.

And need to add #define TB_SETIMAGELIST (WM_USER + 48)  in your commctrl.h

void ToolBar::CreateToolBar(void)
{
 _tbhwnd=CreateWindowEx(WS_EX_DLGMODALFRAME,TOOLBARCLASSNAME,NULL,
         WS_CHILD|WS_VISIBLE|TBSTYLE_FLAT|CCS_ADJUSTABLE|CCS_NODIVIDER,
         0,0,0,0,_hwnd,NULL,_hwnd.GetInstance(),NULL);

 HIMAGELIST hImage;
 HBITMAP hBitImage;
 hBitImage = LoadBitmap(_hwnd.GetInstance(), MAKEINTRESOURCE(IDTB_BMP));
 hImage = ImageList_Create(16, 16, ILC_COLOR32| ILC_MASK , 12, 1);
 ImageList_AddMasked(hImage, hBitImage, RGB(255, 255, 255));
 SendMessage(_tbhwnd, TB_SETIMAGELIST, (WPARAM)0, (WPARAM)hImage);
 DeleteObject(hBitImage);
}


void ToolBar::InitToolBar(void)
{

 tool_bar_buttons[0].iBitmap=0;
 tool_bar_buttons[0].idCommand=CM_FILE_NEW;
 tool_bar_buttons[0].fsState=TBSTATE_ENABLED;
 tool_bar_buttons[0].fsStyle=TBSTYLE_BUTTON;
 tool_bar_buttons[0].dwData =0;
 tool_bar_buttons[0].iString=0;

 tool_bar_buttons[1].iBitmap=1;
 tool_bar_buttons[1].idCommand=CM_FILE_LOAD;
 tool_bar_buttons[1].fsState=TBSTATE_ENABLED;
 tool_bar_buttons[1].fsStyle=TBSTYLE_BUTTON;
 tool_bar_buttons[1].dwData =0;
 tool_bar_buttons[1].iString=0;

 // and others


SendMessage(_tbhwnd,TB_ADDBUTTONS,17,(LPARAM)(LPTBBUTTON)&tool_bar_buttons);

}

Re: [Dev-C++] custom toolbar

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

First, if the toolbar was created with CreateWindowEx, you must send a
TB_BUTTONSTRUCTSIZE message before the TB_ADDBUTTONS.

Second - note the similarity of an array and a pointer. &myarray[0] is
same as myarray, i.e. a pointer to an entry. &myarray is a pointer to a
pointer to an entry. Should you really take the address of tbb as last
parameter of SendMessage().

[Dev-C++] custom toolbar

[Vlada D. <dj...@im...>]

Hi, everybody.

Here's another problem I'm having. I'm trying to create toolbar with my own
bitmap images, so I did the following:

1. I painted one 48x16 pixel bitmap using Paint, which should contain images
for 3 toolbar buttons
2. Defined ID for bitmap resource in header and added a line in .rc file
(ID_BITMAP BITMAP "image.bmp")
3. Finaly, I wrote a code to create toolbar.

--------begin code------
INITCOMMONCONTROLSEX icx;
    icx.dwSize=sizeof(INITCOMMONCONTROLSEX);
    icx.dwICC=ICC_BAR_CLASSES;
    InitCommonControlsEx(&icx);
    HWND hToolbar;

    switch (message)                  /* handle the messages */
    {
        case WM_CREATE:

hToolbar=CreateWindowEx(WS_EX_CLIENTEDGE,TOOLBARCLASSNAME,NULL,WS_CHILD|WS_V
ISIBLE,0,0,0,0,
                        hwnd,(HMENU)ID_TOOLBAR,g_hInstance,NULL);
             if(!hToolbar)
             {
                MessageBox(hwnd,"Couldn't create toolbar","Error",MB_OK);
                return 0;
             }

SendMessage(hToolbar,TB_BUTTONSTRUCTSIZE,(WPARAM)sizeof(TBBUTTON),0);

            TBBUTTON tbb[3];
            TBADDBITMAP tbab;



            tbab.hInst=g_hInstance;;
            tbab.nID=ID_BITMAP;
            SendMessage(hToolbar,TB_ADDBITMAP,(WPARAM)3,(LPARAM)&tbab);

The program compiled, but when I start it, I keep getting "acces violation"
message. I tried using a debugger, but it wont even start (or I dont know
how to use it). When I comment out the line where I send the TB_ADDBITMAP
button, the program works, but without images on buttons, so I suppose
there's something wrong about that .
Can somebody give me some advice what could be wrong, or direct me to some
link about using Dev-Cpp debugger?

[Dev-C++] Pair highlighting, suggestion for improvements

[Anders B. <And...@te...>]

Yes, the pair highlighting feature does kind of work... I admit I did 
not test it so carefully before complaining, but it is still, in my 
opinion, not ideal the way it is now.

First of all, why do I need to press <- when it would be simpler to just 
highlight the ( when I type the )? Ok, if I type ( then ) I need to use 
<- to fill in the contents of the (), but if I type ( then a+b then ) I 
don't.

Second, if I pass through my code with the cursor, it highlights all 
pairs, and it becomes impossible to see which is which.

Third, although the highlighting immediately disappears if I type 
something, it does not disappear when just passing through the code 
using the cursor keys, until I select a region or it goes off screen due 
to PgUp or something.

All these issues would be solved and the feature of matching pairs 
improved if a simpler procedure was implemented:

Just highlight the matching {[( when the corresponding )]} is pressed 
(or passed over with the cursor) and then remove the highlight 
immediately once the next key is pressed, whether this next key is 
alpha-numeric of navigational (arrows, home, end).

Finally, maybe one could improve the colors of the pair highlight? I use 
the Borland color scheme, and the pairs display as white text on white 
background... Would be nice if it is was included in the syntax color 
preferences, so one to change it.

Re: [Dev-C++] using of libs

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

Because the compiler dont looks around in your library path and picks
up file at random. The only exception is that most object file formats
allows the compiler to add a reference to a standard library that the
linker should use. A lot of cimpilers uses that to specify that the linker
should pick up the standard c library.

The linker uses the library path to locate the library files that are
mentioned either in your project, or that are specifically mentioned in
the object files. Including a header file and calling a function from a
library will not add information about a library in the object file. It
will just add the name of the function.

[Vlada D. <dj...@im...>]

Hi!

This is my problem: I'm trying to create a dialog for my app, but I got
stuck in the first step. The compiler gives me the "parse error" and I can't
figure out why. It's in the line beggining with STYLE

-----begin code------
#include "resorource.h"

The IDD_DIALOG, IDC_LIST1,IDC_EDIT1 and IDC_BUTTON1 are all defined in the
included header file. I'm using Dev-Cp 4.9.5.0  and Win2K. Hope somebody can
help  me. Thanks!

P.S. I used MS VC++ resource editor to create the dialog, and then I copied
the above code to my .rc file. Maybe it has something to do with this.

[Dev-C++] using of libs

Hello,

I tried to use Ncurses libraries  the headers are in the preset include
path and the libs are in the lib path set in the lib settings of the
compilor.

Why can I only link my program when I explicitly add these library file
in the Project Options Linker Settings??

Greetings

Re: [Dev-C++] One bug, one solution and one feature request

[David M. <dem...@uw...>]

That's what the current one does.  If you scroll past a bracket, it
highlights the matching one.  If you type one, you press '<-' and it will
highlight the matching one.

RE: [Dev-C++] graphic interface with Dev-C++

[Shane P. <ge...@my...>]

I would recommend that you start at the wxWindows home page:

http://www.wxwindows.org

I have found several good wxWindows forums in the past but I never bookmarked any of them.  I have not looked since then because the documentation is quite good.  I will do a search and let you know what I find.

No the above call is not valid. With the default argument mechanism you can
omit arguments from the right of your passed arguments only. If you want to
pass y and z only, you can pass the default value of x.


If the user can't know the any default value, you can change the order of
the argument list or use a variadic function.

Re: [Dev-C++] default arguments of a function

[Ricardo R. <ri...@un...>]

In this case, perhaps you can try to build a function with
a variable number of arguments:

type function (type argument1,...);

familiar examples of this type of functions are:
printf(const char *,...) and scanf(const char *,...)


Ricardo.

RE: [Dev-C++] graphic interface with Dev-C++

[Shane P. <ge...@my...>]

If you are looking to make plain GUI apps (no games) I would recommend wxWindows.  It has all the functionality you should need and is also completely OO.  It also is pretty popular so there is some good support if you get on the right forums.
