HHP - Debug: Looking for DLLs .. or what?

Lvca22-Dec-04 22:55

Salve,
I'm a developer and I write applications in visual c++ (using eVc++ 4.0) for a Dolphin 9500 . In order to scan barcodes I need to use the functions waConnect(), waDefaultSymbology(), waDisableSymbology(), waEnableSymbology(), waWaitForDecode() and waDisconnect().
I had to include in my project the external dependencies engnapi.h and wadecodece.lib and everything seems to work.
The problem comes out when I try to compile for Debug: the compiler asks for two files: HHPSCANINTERFACE.DLL and WADECODECE.DLL. Both this files are unfoundable for me.
I often need to debug my program, and I really need to solve this problem, have you got any suggestion? Where can I find these files?
(Note: I cannot use ScanWedge to scan my barcodes, so I HAVE TO use the functions written above)

conversion between dialog units and pixels

Hi.

I want to create controls on the dialog box at runtime. I need to convert between dialog units and pixels.

I tried the following:

CFont *pFontDlg= GetFont(); // font of dialog.
LOGFONT logfont;
pFontDlg->GetLogFont(&logfont);

The problem is that the width (logfont.lfWidth)is zero. So I am unable to use the formula. Please help !!!

Thanks....!!!!

This is a very bad idea. Dialog units are used for a reason, namely so that a program does not have to be concerned with what resolution and font are currently in use. By hard-coding controls based on pixel size, you have limited the portability of your program to only one computer. See this comment for more.

Use MapDialogRect() to do that conversion

I have written a program that used mschart and I install this program on the computer that not installed VC. the problem is if I set chart on the dialog directly,all that is ok.but if I create it in my codes dynamically,chart can not be shown. in my computer this problem does not exist,what is the reason?

hi mschart is component usually registered with the MFC. that why u didn't get any problems whem u r working with ur system. If u want to install it some other machine which doesn't have the mschart component, you must explicitly register it with regsrv32 tool

Hi
Simple question. Why the constructor name has to be same as the class name?

You have to set a HOOK on process of type WH_CBT and listen for WM_QUIT,WM_CREATE Messages.

problem with Oleacc

I am trying to get data using OLEACC. It works fine when I fetch data from windows xp machine, however it fails to retrieve unicode data from Richedit20A control on windows 2000 machine. It gives ?????? for any of the unicode characters entered.

Anyone have any idea.

If it works on XP is should work on 2000. Usualy the only time you see ? marks is when the system can not translate from one character code format to anouther. May be you should try making sure that the 2000 machine is up to date as far as the OLEACC is concerned.

I updated my machine after I found this error.

I even used accexplorer to check if this is some problem with my coding and as I thought, result was all the same, even accexplorer cannot get the data.

I found version numbers of dlls being used by these systems are different with XP having the latest, so I replaced those that I can, but no luck.

can i got the item index from the item lparam?

lowiq22-Dec-04 13:39

I have a list ctrl and want to sort it when user click the column. In my sort function, i only can get the item's lparam, but i need get the item's index then could use GetItemText function to compare two strings. I find i could use the FindItem to get the item index from the item's lparam, but it seems slow(if items more than 3000, the sort time is too long). So could any one teach me which function or which way I could use to get the item index effectively?

Thank you very much for your help!

Use LVM_SORTITEMSEX to start the sort, your callback will be passed the two items' indexes.

David Crow23-Dec-04 3:52

Are you calling the list control's SortItems() method? If so, the callback function will receive two LPARAM variables, lParam1 and lParam2. Those are pointers and need to be cast to the same type of object that was used with SetItemData(). For example:

struct myStruct
{
    int i;
    char name[32];
};
...
int nIndex = InsertItem(...);
myStruct *p = new myStruct;
SetItemData(nIndex, (DWORD) p);
...
SortItems(CompareFunc, 0);
...
int CALLBACK CompareFunc( LPARAM lParam1, LPARAM lParam2, LPARAM )
{
    int      nReturn = 0;
    myStruct *p1,
             *p2;
     
    p1 = (myStruct*) lParam1;
    p2 = (myStruct*) lParam2;
    // now compare the members of p1 and p2
    ...
}

Make sense?

send key to window

22-Dec-04 11:49

Hello

How do I send a specific key to a winow?
I tryed using the SendMessage function like this:

SendMessage(hwnd,WM_KEYDOWN,'A',0x2701);

I think it doesn't work because of the 4th parameter and I don't understand that parameter very well.Can anyone explain it to me, it is supposed to be some kind of a value that identifies the repeat count, scan code, extended-key flag, context code, previous key-state flag, and transition-state flag, as shown in the following table. But I don't understand this.

I also tryed sending a hotkey message to the window as I think that the letter I send is actually a hotkey because it is underlined. I tryed doing that like this:

SendMessage(hwnd,WM_HOTKEY,IDHOT_SNAPWINDOW,'A');

But it didn't work. Why?

Is there some other way that I can press a button on this window programaticly? The buttons on this window keep changing every time you run it and they have no names just handles so that would be pretty hard.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
