I am using vc++ 6.00 and I am using drawtext to output text. I am not able to print characters above ascii 127. I tried to make them unsigned char, I also tried the /J option but nothing happens. Please help me.

It will depend on the font that you are using. I assume you are trying to print out characters like the box drawing ones (or foreign language chars). Many of the Windows fonts map only to a small square box (or some other boring shape) for chars above 127. Some of the OEM terminal fonts may be more useful for you. Of course it could be something else that isn't right. You should probably also check if you are using Unicode or not and make sure you are casting your strings with TCHAR - this could impact on it as well. Another thing would be the default language you are using.

Thanks for your kind suggestions Gary.
I was using Foxpro ODBC 2.5. Then I used Visual Foxpro ODBC Driver & the problem was solved.

within my class i created a struct and a CList template containing the struct. but i something goes wrong when i try to add a struct variable to the CList object. Whats wrong?
#include "StdAfx.h"
#include "Afxtempl.h"
//HoleVok.h
class CHoleVok
{
private:
typedef struct TABELLE
{
CString strSQL;
CString intTID;
int intVokAnzahl;
CList<int,int> clistGeprueft;
};
CArray <tabelle,tabelle&> arrTabellen;
CDatabase *db;
public:
bool fnConnect(CDaoDatabase &db);
};
___________________________________________
#include "stdafx.h"
#include "HoleVok.h"
//HoleVok.cpp
bool CHoleVok::fnConnect(CDaoDatabase &db)
{
TABELLE tabTest1;
tabTest1.clistGeprueft.AddTail(20);
tabTest1.clistGeprueft.AddTail(21);
tabTest1.intTID = 4;
tabTest1.intVokAnzahl = 200;
tabTest1.strSQL = "Das Wetter ist schoen";
arrTabellen.Add(tabTest1);
return true;
}

The CList is a template. You need to define what is being stored in its definition. such as.
typedef struct TABELLE
{
CString strSQL;
CString intTID;
int intVokAnzahl;
CList<int,int> clistGeprueft;
};
After this the following works fine.
TABELLE NewTab;
NewTab.clistGeprueft.AddTail(20);
NewTab.clistGeprueft.AddTail(21);
NewTab.clistGeprueft.AddTail(24);
int myval;
myval = NewTab.clistGeprueft.GetHead();
POSITION pos = NewTab.clistGeprueft.GetHeadPosition();
myval = NewTab.clistGeprueft.GetNext(pos);
myval = NewTab.clistGeprueft.GetNext(pos);
myval = NewTab.clistGeprueft.GetNext(pos);
myval = NewTab.clistGeprueft.GetNext(pos);
NOTE the last line here fails because the list had 3 elements and I did not test for a NULL position.

Benedikt,
I missed what the lt gt signs did to the code. Now my sample worked. Can you describe what goes wrong?
Given the code is not being post clearly is the problem with the CList or the CArray?
The following is adding the "pre" html prior to the code just to see what it looks like.
typedef struct TABELLE
{
CString strSQL;
CString intTID;
int VokAnzahl;
CList<int,int> clistGeprueft;
};

I think I've found the problem. CList doesn't provide a copy or an assignement operater witch is needed. So it is not possible to store a clist or a carray within a clist or a carray. But this is what i need!

Hi there.
I am creating a CEdit control using Create method. In that i am specifying the control to be right aligned. It works fine with Win NT. But, it turns centre aligned in Wnidows 95. It works properly in 98 also.
Please let me know if anybody knows the solution.
Thanx.

this is certainly beyond my knowledge to learn that array[-1] is valid in some cases.
i am shocked, stunned and desparate !
i am now examing an existing project and i am suspecting this is the cause of all evils.
but now somebody said this is perfectly legal.
okay okay..
let me draw the picture bigger.
there is this array of struct defined like this..
struct someStruct array[100] and i am assigning like this
array[-1].field1 = something.
so so..is this so called access the return address or read parameter directly ??
arghhh !!! what am i talking about ?? some1 pls resurrect me !!
|
|

|

It's my understanding that a[i] is identically equivalent to *(a + i). No restriction is made on the sign of i, so array[-1] is syntactically fine.
However, in your code example:
struct someStruct array[100];
array[-1].field1 = something;
That is accessing outside the bounds of the array. Bad move. It's just as bad as doing "array[2000].field1=xyz;"
|
|
|
|
|
<br />
It would only be useful in a small number of cases.<br />
<br />
Say, if you wrote a peice of code like this:<br />
<br />
char text[100];<br />
char *ref = text[1];<br />
if(*ref == ref[-1]) return FIRST_EQUALS_SECOND;<br />
<br />
However, I don't see why you would want to do that in any normal case.<br />

I have an INF file with the following sections in it:
[Version]
Signature="$Windows NT$"
Provider=Gooroos Software
[Install]
CopyFiles=CopyFiles
[CopyFiles]
file1
[DestinationDirs]
CopyFiles=11 ; Same as %windir%\system32
[SourceDiskNames]
1="Installation"
[SourceDiskFiles]
file1=1
I can use this INF to install file1 just fine. However, if I try to create a disk space list for the Install section, I get an error. I.e:
SetupAddInstallSectionToDiskSpaceList(diskSpaceList, m_hInf, 0, "Install", 0, 0);
fails and GetLastError() returns a code of -536870654.
If I change the section name from "Install" to "CopyFiles", then the call succeeds, but when I query the drive list I get back an empty string. I.e:
SetupQueryDrivesInDiskSpaceList(diskSpaceList, NULL, 0, &driveListSize)
returns a list size of 1 character (i.e. just the terminating null byte).
Obviously I'm doing something wrong, so does anyone have an example of using a disk space list which actually works?
Thanx.

I've written a Developer Studio 6.0 add-in which changes the project's linker settings using AddToolSettings() and RemoveToolSettings().
Although my changes immediately appear in the Project->Settings windows, none of the Build commands will use the new settings until after I have closed and reopened the
workspace. Not even doing a Build->Clean helps.
Anyone know of a programmatic way of forcing the Build commands to pick up my changes?
Thanx.

Does anybody knows how to integrate CVS version control with the Visual Devstudio IDE? My company is migrating there right now(BIG mistake), so I am trying to find a civilized way to work with it instead of the command line or WinCVS things... Is there any addin available?

Currently there is no real CVS support
for VC++
the only project that I know if doing something like this is
http://members.home.net/preston/cvsscc.html
and they're not even close to being done.
might i offer bitkeeper(out RSN) www.bitkeeper.com, it will integrate into VC++

You may want to have a look at CS-RCS which is based on GNU RCS and integrates with VC++. Their site is http://www.componentsoftware.com/

How to change mouse cursor to "IDC_IBEAM" when move mouse pass the button?
This is my easy win32 code, please edit or modify this code below. Thank you.
#include "afxwin.h"
#define IDC_BUTTON1 100
class CApp:public CWinApp{
public:
virtual BOOL InitInstance();
};
CApp app;
class CWin:public CFrameWnd{
CButton *button;
public:
CWin();
~CWin();
};
BOOL CApp::InitInstance(){
m_pMainWnd=new CWin();
m_pMainWnd->ShowWindow(m_nCmdShow);
m_pMainWnd->UpdateWindow();
return TRUE;
};
CWin::CWin(){
Create(NULL,"Hello",
WS_OVERLAPPEDWINDOW,CRect(0,0,200,200));
button=new CButton();
button->Create("OK",
WS_CHILD|WS_VISIBLE|BS_PUSHBUTTON,
CRect(50,50,100,100),this,IDC_BUTTON1);
}
CWin::~CWin(){
delete button;
}
|
|
|
|
|
Don't quote me on this BUT I think you could try setting the cursor using SetCursor in OnSetCursor - WM_SETCURSOR.
|
|
|
|
|
There are two possible ways of implementing this (that I know of). Both of them include trapping either one or both of the MOUSEMOVE or SETCURSOR messages.
You can either trap them at level of the main FrameWnd or in the Button (I would personally prefer to subclass the Button and trap it in there so I could reuse that new button in other parts of my code). In the case of trapping it in the FrameWnd (probably trapping MOUSEMOVE after you know the cursor is in the FrameWnd - using SETCURSOR to set some flag) you then need to work out if the mouse is over the button to change to the IBEAM cursor - as well as not over the button to change it back!!).
There are probably other pitfalls to worry about that my simple explanation doesn't cover but they would be the two basic approaches to consider.

Gary Menzel

I developed a dll with a class exported. In my application, I declare an object of it and call one of its member functions. I got the following link time error:
error LNK2001: unsolved external symbol "__declspec(dllimport) public:void __thiscall testclass::function(char const *)" (__imp_?Export@testclass@@QAEXPBD@Z)
When I look at the dll, I see
...
314 139 00001131 ?function@testclass@@QAEXPBG@Z
Apparently there is a mismatch here. I would like to know the reason of this problem. Any ideas?

Hi!
You have to declare the class as "__declspec(dllimport)". And you also have to include the *.LIB file for your DLL. You can do this in the Link section of your project settings or by inserting the pragama in the source code. For example:
#pragma comment(lib, "MyClass.lib")

How could I make status bar to show tool tips for its panes?
Regards,
Stefan
----------
|
|
|

Stefan,
If the items in your status bar have ID's, then you can add them to a tooltip object like so:
CWnd* pSomeItem = GetDlgItem(IDC_SOMEID);
m_tooltip.Create(this);
m_tooltip.Activate(TRUE);
m_tooltip.AddTool(&pSomeItem, "A tool tip");
Then, in your mainframe do the following:
BOOL CMainFrame::PreTranslateMessage(MSG* pMsg)
{
// Let the ToolTip process messages.
m_tooltip.RelayEvent(pMsg);
return CMDIFrameWnd::PreTranslateMessage(pMsg);
}
This might work.

Have you tried:
SendMessage
(
hStatusBarWnd,
SB_SETTIPTEXT,
(WPARAM)(INT)iStatusBarPart,
(LPARAM)(LPCTSTR)lpcszTextToDisplayAsTooltip
);
code sequence?
The status bar window must be created (as in the following example) using
g_hStatusBarWnd =
CreateWindowEx
(
0L,
STATUSCLASSNAME,
0,
WS_CHILD | WS_VISIBLE | SBT_TOOLTIPS,
0,
0,
0,
0,
hParentWnd,
(HMENU)ID_STATUSBAR,
g_hInstance,
0
);
For more information, you can check the WindowsNT System Manager, where you can find, among other stuff like this, also something about status bar APIs.
All the best,
Sardaukar
