Hello everyone,
I have a bunch of dynamically created static controls on my MFC dialog.
I would like the user to be able to click on those. So how do I map the notification message from the control to a handler function?
I have no problem mapping the message from a static control created at designtime:
<br />
BEGIN_MESSAGE_MAP(CSomeprojectDlg, CDialog)<br />
...<br />
ON_STN_CLICKED(IDC_STATIC_TEST, OnStnClickedStatic)<br />
...<br />
END_MESSAGE_MAP()<br />
<br />
BOOL CSomeprojectDlg::OnInitDialog()<br />
{<br />
...<br />
GetDlgItem(IDC_STATIC_TEST)->ModifyStyle(0, SS_NOTIFY);<br />
...<br />
}<br />
<br />
void CSomeprojectDlg::OnStnClickedStaticTest()<br />
{<br />
MessageBox("Hello");<br />
}<br />
My code when creating the controls programatically:
<br />
BOOL CSomeprojectDlg::OnInitDialog()<br />
{<br />
...<br />
#define FirstID 2000<br />
<br />
for(i=1; i<=10; i++)<br />
{<br />
pWnd= new CWnd;<br />
pWnd->Create(_T("STATIC"), "SomeText", WS_CHILD | WS_VISIBLE | SS_NOTIFY, CRect(x_pos1, y_pos1, x_pos2, y_pos2), AfxGetMainWnd(), FirstID + i);<br />
}<br />
...<br />
}<br />
<br />
Thanks

This step is unnecessary here, as you have already mentioned SS_NOTIFY style while creating control.

Set this dilaog as parent of the static text. Modify your code to,
pWnd= new CWnd;
pWnd->Create(_T("STATIC"), "SomeText", WS_CHILD | WS_VISIBLE | SS_NOTIFY, CRect(x_pos1, y_pos1, x_pos2, y_pos2), m_hWnd, FirstID + i);
If one of FirstID + i is equal to IDC_STATIC_TEST , handler OnStnClickedStaticTest will be called.

This line is when I create the control with the Ressource view and toolbox in VS, not when creating the controls programatically.

True, but will I then need one ON_STN_CLICKED(ID, OnStnClickedStaticTest) for each control I create? That's a lot of work and the easy part of creating the static controls programatically is kind of gone.
I was thinking more of a general handler for all the controls, that is called whenever the app receives the notification and can check to see which control the user clicked.
Is that possible, if yes, how?

Use ON_CONTROL_RANGE.
Your code would be modified like this,
BEGIN_MESSAGE_MAP(CSomeprojectDlg, CDialog)
...
ON_CONTROL_RANGE(STN_CLICKED,ID_STATIC_FIRST,IDC_STATIC_LAST,OnStnClickedStaticTest)
...
END_MESSAGE_MAP()
void CSomeprojectDlg::OnStnClickedStaticTest(UINT nIdOfControl)
{
MessageBox("Hello");
}

END_MESSAGE_MAP()
void CSomeprojectDlg::OnStnClickedStaticTest(UINT nIdOfControl)
{
//check ids if needed
MessageBox("Hello");
}
Exactly what I needed, thanks!

Hi,
I have an MFC doc/view application and I wish to exit gracefully if the view does not initialise correctly. At the moment I return -1 from OnCreate() as per the documentation but this gives the "Failed to create an empty document" message which is hardly helpful to the user.
If I post a WM_CLOSE message I still get the same problem because it doesnt get processed until the view has completed its initialisation.
Any suggestions? 
Tony

Use PostQuitMessage(0); in case view initializatin is failed.
i.e
int CMyView::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CView::OnCreate(lpCreateStruct) == -1)
return -1;
if (bFailed)
{
PostQuitMessage(0);
}
return 0;
}

Great thanks - that does the trick.

Hi all:
I've implemented the MSI package rendering through progress bar using MsiSetExternalUI. But it seems the installation process was divided into several rounds, this way the progress will reset several times, I was wondering is it possible to render it as a single coherent progress?

Thanks

Check if directory containing stdafx.h is mentioned in tools-->options-->Additional include directories, if its not present in same direcotry as project file.

I have this code that does a linear search within two files, but it is too slow......
<br />
<br />
for(unsigned i=0;i<Standard.size();i++) <br />
{<br />
for(unsigned j=0;j<MyWords.size();j++) <br />
{<br />
string::size_type FoundAt=MyWords[i].find(Standard[j]);<br />
while( string::npos != FoundAt )<br />
{<br />
MyWords[i].replace( FoundAt, Standard[j].length(),Standard[j]+"/");<br />
FoundAt = MyWords[i].find( Standard[j], FoundAt + Standard[j].length() );<br />
}<br />
}<br />
}<br />
<br />
for(unsigned j=0;j<MyWords.size();j++) <br />
{<br />
WriteWord<<MyWords[j]<<endl;
}<br />
WriteWord.flush();
WriteWord.close(); */
return 0;<br />
}<br />
I want to change it into [I]binarysearch so it will perform faster, but the problem is I don't know how can I do that, I mean, if I change it to binarysearch the structure itself will have to be changed. I have the following questions that I can't solve so the binarysearch can be done:
1. Cut the sentences into words.
2. Compare first word of the sentences and see if matches, if match take second and so on till a phrase in my standard file is formed. Otherwise, discard word.
e.g. Lets say I have a sentences "This world is full of beauty!" and I have in my sorted array the phrase "full of beauty", I would like to take each word of the sentence to and compare it with my array like the following:
1. Take the word "This", since it doesn't match delete it
2. Take the word "world", since it doesn't match delete it.
3. and so on until "full", since "full" is part of my phrase "full of beauty" conserve it and take the next and compare it, and so on till I get the full phrase "full of beauty" then return that the phrase was found.
Hope someone can give me some hint, I really need to get this thing to work, and want to get it work myself but I really can't do. Thanks in advance to all.
Regards
Jing

Did you look at your posted code after you posted it. You need to read the CodeProject instructions for posting code.

Binary search is for "sorted" data. Sentences are generally not sorted.

Yes I know that BinarySearch is for sorted arrays,my array is sorted but is in a file. I have I sort array of phrases which I named as standard, it contains 400 phrases sorted in alphabetical order. Then I have another file that contains lets say 1000 sentences, I want to cut this sentences into words, then do the comparison.
e.g. in the sentences I there is the word "excellent" , I want to take that word, and look if there is any phrase in my array that begins with that word, if true take the next word, if false discard the word and take next one.
Lets say I have in my array "excellent job" and "excellent work" so I will have to check the next word to make sure which is the match. And if the word that follows "excellent" is not neither discard, if is any of both return true.
Now, I know that I should chop the sentences into words, compare and concatenate the words that match to form my phrase and then return a value. Then, how shall I chop the sentences into words and then concatenate them again to form a phrase?

Yeah I don't know, your subject says "LinearSearch to BinarySearch". The question you just asked does not seem to have any connection to your subject.

Decoding JPEG and encoding MPEG-1 is a long topic.
There's plenty of ways built-in to Windows to decode JPEG but for encoding MPEG there's none
because of licensing.
Maybe search Google for open-source/free MPEG-1 encoders - or maybe you can write your own

Send message is not used to send messages between classes but to send a message to a specific window. If your class is not managing a window, then you cannot send a message to it.

Use SendMessage() or PostMessage().
