Hi!
First of all, sorry for my poor English and my stupidity.
I've been attempting to include the header file "cesync.h" in a vs2005 project and I don't know how the hell I'm getting lots of errors such as:
error C2065: '_JBLEN': undeclared identifier (file stdlib.h)
and many others...
About the code, all I have to say is that it's a new project (from scratch) and the include has been added before any other line in the .h auto-generated code. Thanks.

Hi there,
I am creating an application where one dialog box has a tab control with multiple tabs. I am having difficulties setting it up and would appreciate anyone who can shine some light on the issue. The program runs perfectly with the other controls but when one of my DialogProcs are called via a pushbutton control I get an unhandled exception error. Below is the code for your perusal:
<br />
<br />
BOOL CALLBACK OptionsDialogProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)<br />
{<br />
HWND tab1_hwnd, tab2_hwnd, CurrentTabHwnd;<br />
int CurrentTabIndex;<br />
HWND hwndTab;<br />
<br />
switch(msg)<br />
{<br />
case WM_INITDIALOG:<br />
{<br />
<br />
LPSTR tab1_title = "General";<br />
LPSTR tab2_title = "Advanced";<br />
<br />
LPINITCOMMONCONTROLSEX tabctl;<br />
<br />
tabctl->dwSize = sizeof(tabctl);<br />
tabctl->dwICC = ICC_TAB_CLASSES;<br />
<br />
InitCommonControlsEx(tabctl);<br />
<br />
hwndTab = GetDlgItem(hwnd,IDC_TAB1);<br />
<br />
TCITEM* ItemStruct;<br />
<br />
ItemStruct->mask = TCIF_TEXT;<br />
ItemStruct->pszText = tab1_title;<br />
ItemStruct->cchTextMax = sizeof(tab1_title);<br />
ItemStruct->iImage = 0;<br />
ItemStruct->lParam = 0;<br />
<br />
SendMessage(hwndTab, TCM_INSERTITEM, 0, (LPARAM)ItemStruct);<br />
<br />
ItemStruct->pszText = tab2_title;<br />
ItemStruct->cchTextMax = sizeof(tab2_title);<br />
<br />
SendMessage(hwndTab, TCM_INSERTITEM, 1, (LPARAM)ItemStruct);<br />
<br />
tab1_hwnd = CreateDialogParam(GetModuleHandle(NULL), MAKEINTRESOURCE(IDD_OPTIONS_GENERAL), hwndTab, General_OptionsDialogProc, 0);<br />
tab2_hwnd = CreateDialogParam(GetModuleHandle(NULL), MAKEINTRESOURCE(IDD_OPTIONS_ADVANCED), hwndTab, Advanced_OptionsDialogProc, 0);<br />
<br />
CurrentTabIndex = 0;<br />
<br />
if(!ShowWindow(tab1_hwnd,SW_SHOWDEFAULT))<br />
MessageBox(hwnd, "Could not initiate InitCommonControlsEx command", "Error:", MB_OK | MB_ICONINFORMATION);<br />
<br />
<br />
<br />
}<br />
break;<br />
<br />
case WM_NOTIFY:<br />
{<br />
switch(LOWORD(wParam)){<br />
case TCN_SELCHANGE:<br />
{<br />
ShowWindow(CurrentTabHwnd, SW_HIDE);<br />
CurrentTabIndex = SendMessage(hwndTab, TCM_GETCURSEL, 0, 0);<br />
<br />
switch(CurrentTabIndex){<br />
case 0:<br />
ShowWindow(tab1_hwnd,SW_SHOWDEFAULT);<br />
CurrentTabHwnd = tab1_hwnd;<br />
break;<br />
case 1:<br />
ShowWindow(tab2_hwnd,SW_SHOWDEFAULT);<br />
CurrentTabHwnd = tab1_hwnd;<br />
break;<br />
}<br />
<br />
<br />
<br />
}<br />
break;<br />
default:<br />
return FALSE; <br />
}<br />
<br />
}<br />
break;<br />
<br />
case WM_COMMAND:<br />
{<br />
<br />
switch(LOWORD(wParam)){<br />
<br />
case IDOK:<br />
EndDialog(hwnd,0);<br />
break;<br />
case IDCANCEL:<br />
EndDialog(hwnd,0);<br />
break;<br />
}<br />
<br />
}<br />
break;<br />
case WM_CLOSE:<br />
EndDialog(hwnd, 0);<br />
break;<br />
<br />
default:<br />
return FALSE;<br />
}<br />
return 0;<br />
}<br />
<br />
<br />
Running it through my debugger it appears that the program experiences an error at this location:
<br />
tabctl->dwSize = sizeof(tabctl);<br />
tabctl->dwICC = ICC_TAB_CLASSES;<br />
I have also included the resources as well:
<br />
<br />
IDD_OPTIONS DIALOG DISCARDABLE 0, 0, 271, 166<br />
STYLE DS_MODALFRAME | WS_POPUP | WS_CAPTION | WS_SYSMENU<br />

BEGIN<br />
DEFPUSHBUTTON "OK",IDOK,7,145,50,14<br />
PUSHBUTTON "Cancel",IDCANCEL,214,145,50,14<br />
CONTROL "Tab1",IDC_TAB1,"SysTabControl32",0x0,7,7,257,124<br />
END<br />
<br />
IDD_OPTIONS_GENERAL DIALOG DISCARDABLE 20, 15, 150, 60<br />
STYLE WS_CHILD<br />
FONT 8, "MS Sans Serif"<br />
BEGIN<br />
GROUPBOX "",IDC_STATIC,15,11,118,38<br />
LTEXT "General Tab",IDC_STATIC,53,26,44,8<br />
END<br />
<br />
<br />
IDD_OPTIONS_ADVANCED DIALOG DISCARDABLE 20, 15, 150, 60<br />
STYLE WS_CHILD<br />
FONT 8, "MS Sans Serif"<br />
BEGIN<br />
GROUPBOX "",IDC_STATIC,15,11,118,38<br />
LTEXT "Advanced Tab",IDC_STATIC,53,26,44,8<br />
END<br />
<br />
Everything looks to be correct so I am not sure as to what could be causing the issue. If this is of any help I am getting these compiler warnings as well:
C:\Program Files\Microsoft Visual Studio\MyProjects\RS_Stats32\RS_Stats32.cpp(95) : warning C4700: local variable 'tabctl' used without having been initialized

C:\Program Files\Microsoft Visual Studio\MyProjects\RS_Stats32\RS_Stats32.cpp(146) : warning C4700: local variable 'tab2_hwnd' used without having been initialized
If you need some more information just give me a shout. Just FYI I am running on VC++ 6.0 on a WinXP machine.
Thanks,
Robbie

Setting dwSize to the sizeof( a pointer) is not correct.

Hey Led,
Thanks for your reply. I dereferenced the pointer but I am still receiving the same error. I checked on google and someone some how was able to get it working by doing this:
<br />
LPINITCOMMONCONTROLSEX lpInitCommonControlsEx;<br />
<br />
lpInitCommonControlsEx.dwSize = (LPINITCOMMONCONTROLSEX);<br />
I'm not sure how that would even work but the person had successful results. I tried it with my code and I received syntax errors so I don't believe thats correct.
Did you have another idea how I could fix this?
Thanks,
Robbie

Robbie, DavidCrow has your "fix". I would be more concerned that you are writing C/C++ code but do not understand "how" these things work, or don't, as the case may be. This is a very fundamental aspect of C/C++ development. You should take the time to understand this before continuing on with the project.
good luck

LPINITCOMMONCONTROLSEX tabctl;
tabctl->dwSize = sizeof(tabctl);
tabctl->dwICC = ICC_TAB_CLASSES; You are dereferencing an uninitialized pointer, this is causing the crash.
TCITEM* ItemStruct;
ItemStruct->mask = TCIF_TEXT;
ItemStruct->pszText = tab1_title;
ItemStruct->cchTextMax = sizeof(tab1_title);
ItemStruct->iImage = 0;
ItemStruct->lParam = 0; Same problem here.

I tried the fix David gave but that wasn't the main problem (I already tried the way David had stated before so I know that wasnt the problem). I realized, instead of passing a pointer to InitCommonControlsEx function, I thought I would define the original structure (INITCOMMONCONTROLSEX) and pass it via reference to the InitCommonControlsEx function. That actually worked.
However I am running into another problem. The options Dialog appears and shows it has 2 tabs. However when the 2nd tab is clicked, it becomes "on top" or becomes focused, but the dialog control associated with it does not appear below the tab. Basically if I click any tab, it shows only the dialog control associated with the general tab (1st tab) and not the dialog controls associated with the tab that was chosen by the user. Below is the code for your perusal:
<br />
BOOL CALLBACK OptionsDialogProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)<br />
{<br />
HWND tab1_hwnd = NULL;<br />
HWND tab2_hwnd = NULL;<br />
HWND CurrentTabHwnd = NULL;<br />
int CurrentTabIndex;<br />
HWND hwndTab = NULL;<br />
<br />
switch(msg)<br />
{<br />
case WM_INITDIALOG:<br />
{<br />
<br />

LPSTR tab2_title = "Advanced";<br />
<br />

<br />

<br />
SendMessage(hwndTab, TCM_INSERTITEM, 0, (LPARAM)&ItemStruct);<br />

CurrentTabIndex = 0;<br />
break;<br />
case 1:<br />
ShowWindow(tab2_hwnd,SW_SHOWDEFAULT);<br />
CurrentTabHwnd = tab1_hwnd;<br />
CurrentTabIndex = 1;<br />
break;<br />
}<br />
}<br />
break;<br />
default:<br />
return FALSE; <br />
}<br />
<br />
}<br />
break;<br />
case WM_COMMAND:<br />
{<br />
<br />
switch(LOWORD(wParam)){<br />
<br />

break;<br />
<br />
default:<br />
return FALSE;<br />
}<br />
return 0;<br />
}<br />
<br />
<br />
I know the problem is for sure occuring at the WM_NOTIFY case and even more specifically the "case TCN_SELCHANGING" code block.
I want to know how do I find out through the message system which tab index is selected? If I can find out which tab index is selected then I can easily write code that will show the appropriate dialog window under the selected tab.
Thanks for your help,
Robbie

Can anyone point me to a copy of the source code to this old library anywhere?
I'm trying to port a project into VS2005 which has some old dependencies on this libary. I finally resolve all my compilation erros in my code only to discove VS2005 won't link to the old CJLibrary .lib files I have.
I think I need to rebuild the CJ .lib files using VS2005 - but I don't seem to have the full source any longer. It seems to have vanished from the net entirely.
I gather its been replaced by an all singing all dancing commercial version - but I can't find any reference anywhere to the old code. The new version looks to have totally changed so wouldn't be suitable. But the old free v6.09 library must be about somewhere!
Cheers

I have a splitter with tree control in left pane and need to display bitmaps in the right pane.
There are many nice splitter samples here but none of them explains how to interact between left and right panes.
I tried to send message from parent to siblings but it did not work.
Thanks for reading.

You want to interact between the "Views" in the panes yes? One way is to use CDocument::UpdateAllViews(...)
|
|

|

Not really,
I want the left pane tree control OnSelectionChanged method to display bitmap in the right pane.
Actually I want to have tab control in the right pane to display selected bitmas as required.
I can figure out the tab, for now I just need to interact from left pane to right.

Check the Dr Watson log for more information. Access Violations are a bit too general to be able to narrow down your problem. Any other information about your app would help others help you as well.

Are you using any CRITICAL_SECTIONs, or using any libraries that use them internally? Also, are you doing any custom heap management?
If the former, I would check to see that valid CRITICAL_SECTION objects are being maintained correctly. If the latter, I would check that all heap HANDLEs are being maintained correctly.
Peace!
