Re: I need a programm in C Hexadecimal to decimal

Do you need to convert an hexadecimal representation of a number (i.e. a string, like "5f") to an int value? If the answer is yes then you may try strtol [^], for instance:

int i = strtol("5f", NULL, 16);

If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Bitmap::FromResource(HINSTANCE, WCHAR) , problem

I use the code "Bitmap::FromResource(HINSTANCE, WCHAR)" to load the bmp pic form res and then to fill a rectangle.but can not get a bitmap.

My project is mfc project. so my first question is how to get hte handle of the HINSTANTCE and the second is the wchar parameter, I use "MAKEINTRESOURCE(pResId)" to get he pic name, but get a blank.
and why? whether the gdi+ need more configuration or any other reason.

below is my the whole code

hInstResource  = AfxFindResourceHandle(MAKEINTRESOURCE(pResId), RT_BITMAP);

CString src = MAKEINTRESOURCE(pResId); 
 
int strLen = 0;

strLen =src.GetLength();

WCHAR* ch = new WCHAR[strLen];

wcscpy(ch, CT2CW(src));

Bitmap* pBitmap = Bitmap::FromResource(hInstResource, ch);

if(!FindResource(hInstResource, src, RT_BITMAP))
{
AfxMessageBox("Fail load pic!", MB_OK, 0);
}

graphics.DrawImage(pBitmap,  75,35);

TextureBrush* pTextureBrush = new TextureBrush(pBitmap, WrapModeTileFlipY);

graphics.FillRectangle(pTextureBrush, 50,300,200,80);

Color m_penColor(233,100,54);

Pen pen1(m_penColor, 1);

graphics.DrawRectangle(&pen1, 50,300,200,80);

I have already resolved it

first: hinstance = AfxGetInstanceHandle();

second: FromResource(hInstResource, (LPCWSTR)MAKEINTRESOURCE(pResId));

CFileDialog and Vista + Win7 problem!

Hello community,
i make my own CFileDialogEx derived from CFileDialog, with some new controls on it, but if i run my program on
vista or win7, this new controls are not visible, mean, it is the standard Vista File dialog showed,
but not my own!
How to solve this, so that my CFileDialogEx is showed??
The constructor of my file dialog is called, but newer this OnInitDialog() of my custom file dialog!! Frown | :(

In the MSDN says that there is a new parameter BOOL bVistaStyle and i set them to FALSE, but i see again the vista standard CFileDialog, not my own!! Frown | :(

Does any one have a idea how to solve this, so i can use my custom CFileDialogEx(derived from CFileDialog)!?
I hope its understandably what i have wrote Frown | :(

In XP is all there, my complete CFileDialogEx!

thanks for any help!

I've used CFileDialog with extra UI (extra dialog) attached to it, and had to use the new bVistaStyle flag to make it work on Vista; the constructor gets called, as well as the OnInitDialog.

class MyFileDialog: public CFileDialog
{
//...
	DECLARE_DYNAMIC(MyFileDialog)
//...
};

MyFileDialog::MyFileDialog(LPCTSTR lpszFilter , LPCTSTR lpszDefExt, LPCTSTR lpszFileName, CWnd* pParentWnd) :
		CFileDialog(TRUE, lpszDefExt, lpszFileName, 	
			OFN_ALLOWMULTISELECT | OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT | OFN_SHOWHELP | OFN_EXPLORER | OFN_ENABLETEMPLATE , lpszFilter, pParentWnd, 0, <code>FALSE</code>)
{
//...
	//add custom controls in CFileDialog
	SetTemplate(0,IDD_MYCUSTOM_DIALOG);
//...
}

I don't think we do any other initializations for the application.

Can you try it with a simple barebone project ?
good luck.

Hi,
thanx for answer, and i have a own dialog with controls that i show bottom of this standard CFileDialog controls, bottom of combobox of file types.

And the constructor gets called too, but not the OnInitDialog() of my custom dialog(its a modeless dialog as parent), i work on XP system!

I try with SetTemplate()!

Hi,
I want to display one scrollbar in my view class.
So i created the scrollbar in OnCreate() of view class.
void CTrendView::OnCreate(LPCREATESTRUCT l)
{
CView::OnCreate (l);

HScroll.Create(SBS_HORZ | SBS_TOPALIGN | WS_CHILD | WS_VISIBLE, CRect( 10,10,200,15), this, 1);

}
I declared HScroll in .h file
CScrollBar HScroll;

But the scrollbar doesnot get displayed in my view.

Did i miss anything?

If your view class is drived from CView, replace all CView with CScrollView
then you can use scrollbars easily!

Derive your view class from CScrollView instead of CView, both scrollbar comes automatically, don't forget to set ScrollInfo

.DrawText makes my app laggy/sluggish (MFC C++)

Hi,

I've search throughout the net, cant find any solution. Hope someone able to help me.

My apps had a panel which can draw many rect. The app can be moved by draggin left/right using mouse. Whenever i moved the panel, it'll try to move all the rectangle to top/bottom/left/right following the mouse motion. When the mouse move, it will force the rectangle to be redraw. My app become laggy whenever i use .DrawText to a multiple line of text inside the rectangle.

I have around 80++ rect which used .DrawText to display the text on each rect.

I've tested, if the text is only 1 short words without /r/n (one line), then it will display nicely without laggy.
eg:

Alice

But if the text is in multiline (about 4~5 lines) i tried to run .DrawText, it makes my apps lagg.
eg:

Alice
in
wonderland

Any idea ??

The command i used :

dc.DrawText(strDraw, rcText, DT_LEFT | DT_WORD_ELLIPSIS);

Regards,
KH

good

such drawing problems can be solved via drawing in a memory bitmap and only blitting it to screen.

install the oracle client on the machine - your DBA should have the client CD as part of the distribution (I think the client can also be downloaded from Oracle if you have a developer ID)
