hi, i was developing a plug-in for IE regarding image. I'm looking for event handler which will get fired whenever a image is found, or downloaded/loaded, or by user's command.(e.g. by IE itself will display email to fren etc whenever u right click on a image, and only on a image)
may be i can make use of DWebBrowserEvent2 , e.g. BeforeNavigate2,DownloadBegin,DownComplate etc, but how to i specify it so it only works to a image file ?
any help is much appreciated, thx a lot

Hi All,
I am fairly new to C++ (but don't hold that against me) and I am trying to manually load a 32-bit bitmap into memory from a file. By manually I mean reading each structure (BITMAPFILEHEADER, BITMAPINFOHEADER, etc.) and bitmap bits using ReadFile. I am pretty confused about how the bitmap bits are stored... are they stored BGR or RGB? and where is the alpha bit stored? If after reading the bits into memory and have an UCHAR* to the bits, how do I extract the blue, green, red and alpha color intensities?
Thanks.

I have a simple MFC custom control which extends CWnd.
It has a CButton member, nothing more.
I want to create the Custom control at run time in my main dialog (i.e. Without using Resource editor)
And I want to use the following code in the OnInitDialog() to create the Custom control at run time:
m_MyCustomControl.Create(...);
It sounds simple, but I was failed to do it. Can somebody try out it or gives me some help?

Hey! I've been floating around in here for a while now, doing my thing, helping out where I can. Now I got another request from you all. I need/want to assign an icon to my CMD-LINE programs. I know it can be done, the guys over at FoundStone do it all the time. Requesting suggestions and/or code from you all.
Cheers!

Simply add an icon resource to your .exe. Visual Studio does not automatically create resources and icons for console apps, as it does with dialog based ones, which is why the have no icon by default.
Windows uses the first icon in the resources as the app icon by default.
Cheers,
Nick

Background: I have a standard win32 application. The application doesn't have a user interface and behaves somewhat like a service. However I can't run it as a service because I sometimes need to use the desktop.
I need to make sure that my program exists gracefully on any error. I need to illiminate absolutely all error message boxes like "Runtime error" "Abnormal termination" message boxes. How can this be done??

To begin use
try
{
}
catch(...)
{
}
or catch every error you might know
<italic>Work hard and a bit of luck is the key to success. You don`t need to be genius, to be rich.

 I've used the catch(...) but that doesn't garantee that "Runtime Error! .... This application has requested the Runtime to terminate it in an unusual way." message box doesn't show up.

>>However I can't run it as a service because I sometimes need to use the desktop.
You can make a service to display user interfaces and receive user inputs by setting SERVICE_INTERACTIVE_PROCESS attribute of a service.

Hello,
Does anyone know where to find a reference to a large calendar control? I would like it to look more like a standard wall-hanging calendar (not the date picker in MFC) in which I'll write/paint words and icons and colors.
thanks in advance,
JennyP

This is tne final step in my program and I cannot figure it out. Where do I enter the line with the slashes next to them? I changed the number to amount in the program. In the posoiton they are in I get 19 errors.Below is what was given:
string input;
int number;
int pos = input.find(',');
while (pos != -1)
{
////input.replace(pos, 1, "");
////pos = input.find(',');
}
number = atoi(input.c_str());
cout << number<< endl;
This is what I done.
int main()
{
int c;
float fee;
double total;
char a ='y', ans;
////string input;
//// int amount;
while(a =='y'|| a =='Y')
{
cout << "\nChoose from options below.\n";
cout << "\nEnter A to calculate total RWA cost.\n";
cout << "\nEnter B to calculate RWA base estimate.\n";
cout << "\n\t\tEnter your choice, then press the enter key:";
cin >> ans;
cin.ignore();
if (ans == 'A' || ans == 'a' ){
cout << "\nEnter RWA Base Estimate, then press the enter key:$";
cin >> amount;
////int pos = input.find(',');
////while (pos != -1)
////{
////input.replace(pos, 1, "");
////pos = input.find(',');
////}
////amount = atoi(input.c_str());
////cout << amount<< endl;
cout << fixed;
cout.precision(2);
fee = amount * 0.04;
cout << "4% Management Fee:$" << fee <<"\n";
total = amount + fee;
cout << fixed;
cout.precision(2);
cout << "Total:$" << total <<"\n";

You have everything in the correct place. Just change the line
cin >> amount; to
cin >> input;
I ran the code as posted here (added missing closing braces) and it ran fine.

Hello,
I'd like my app to have 1 document and 3 concurrent views. These views must also be shown and hidden at the users' discretions, and they're to be in separate child windows. I've searched the articles and the internet but only found discussions about splitters and flipping between views one at a time.
Can anyone point me in the right direction?
thanks,
JennyP

It's been awhile since I did this, but this can be accomplished using an MDI interface. The first step is to match all your documents, child frame, and view classes together. This is done in your apps InitInstance function
CMultiDocTemplate* pDocTemplate = new CMultiDocTemplate(
IDR_MY_TYPE_ONE,
RUNTIME_CLASS(CMyDoc),
RUNTIME_CLASS(CChildFrame),
RUNTIME_CLASS(CMyView1));
AddDocTemplate(pDocTemplate);
pDocTemplate = new CMultiDocTemplate (
IDR_MY_TYPE_TWO,
RUNTIME_CLASS(CMyDoc),
RUNTIME_CLASS(CChildFrame),
RUNTIME_CLASS(CMyView2));
AddDocTemplate(pDocTemplate);
CMainFrame* pMainFrame = new CMainFrame;
The IDR_MY_TYPE_ONE and IDR_MY_TYPE_TWO are the resource defines for the string table strings that that name your templates.
IDR_MY_TYPE_ONE "\nTypeOne\n"
IDR_MY_TYPE_TWO "\nTypeTwo\n" The string after the first newline (\n) is used to name the document template.
You then have to override CMainFrame::OnFileNew() so that it uses the proper template
void CMainFrame::OnFileNew()
{
CDocTemplate *pTemplate = GetTemplate(_T("TypeTwo"));
if (pTemplate)
pTemplate->OpenDocumentFile(NULL);
}In CMainFrame::OnFileOpen you would pass the file name to OpenDocumentFile().
To open a new view of an already open document, you have to add the menu message handlers to your document class
void CMyDoc::OnNewViewTypeOne()
{
CDocTemplate *pDocTemplate = GetTemplate(_T("TypeOne"));
if (pDocTemplate)
{
CFrameWnd *pFrame = pDocTemplate->CreateNewFrame(this, NULL);
if (pFrame)
pFrame->InitialUpdateFrame(this, TRUE);
}
}
Here is the code for GetTemplate
CDocTemplate *GetTemplate (CString str)
{
CString strDoc;
CDocTemplate *pTemplate = NULL;
bool templatefound = false;
POSITION pos = AfxGetApp()->m_pDocManager->GetFirstDocTemplatePosition();
while (pos)
{
pTemplate = (CDocTemplate *)AfxGetApp()->m_pDocManager->GetNextDocTemplate(pos);
pTemplate->GetDocString(strDoc, CDocTemplate::docName);
if (strDoc == str)
{
templatefound = true;
break;
}
}
if (!templatefound)
{
TRACE (_T("GetTemplate() failed, Template not found"));
return NULL;
}
return pTemplate;
}There may be bits I am missing, but this should get you started.

Thanks for the help.
When implementing this code, my application runs, but upon startup, it pops-up an MFC dialog titled "New" which contains my two views and expects me to pick either one. If I hit cancel, no document is loaded; else, the app behaves correctly. How do I default a view (instead of asking the user to choose), and how do I show both views simultaneously?
thanks!

In your app's InitInstance function, there is a call to ProcessShellCommand. Remove that line. You then have to process the command line yourself. Look up CommandLineInfo in MSDN for all the possible options.
For example, if your user opens your app by double clicking on one of your associated files in explorer
if (cmdInfo.m_nShellCommand == CommandLineInfo::FileOpen)
{
CDocTemplate *pTemplate = GetTemplate(_T("TypeOne"));
if (pTemplate)
pTemplate->OpenDocumentFile(cmdInfo.m_strFileName);
}

Hello,
Thanks for the help. Just to make sure your solution matches my needs: I would like to have several views operate/interact with the same open document data set simultaneously. Is this the case here? I'm a little suspicious because perhaps MFC is asking about which document (data set) to open upon startup?
Also, is there an easier way to simply display the same document data in separate child windows rather than creating templates? I'm not complaining about the implementation, but in the back of my head, I'm thinking that manually starting and maintaining a child view would be pretty straight-forward. I would just have the added task of manually messaging this new window to update itself at the right times.
thanks,
JennyP

Yes.

No, MFC is asking which view to use to display the data. If you had multiple CDocument classes then the question would be which document, but AFAIK you have only one CDocument class.

No, the templates are the core of the MFC Doc/View model

It's not all that difficult. As long as you remember that the document is the central part of your app. All your views do is display your data and pass any user input onto your document. Do not do any actual data manipulation in your CView classes, do it all in your CDocument classes. Whenever you do data manipulation, simply call UpdateAllViews and the MFC framework will update all the active views that are displaying data from the current document.

This will happen if you have more than one document template defined when the commandline parameters are processed. You can either: Define all the templates except one after the parameters are processed, or modify the parameter processing to prevent this behaviour. The defailt parameter processing calls OnFileNew() which shows the New dialog box if there are multiple document templates.
