Search Engines :: Winsock valikac17-Jun-02 7:13 valikac 17-Jun-02 7:13  Hi. I will begin work on a feature in a program to do a search on search engines such as Google and Yahoo. For example, the user will type in whatever phrase he/she wants such as "race & cars," and the program will do a search via Google and print the responses. I am not sure what message I need to send and where to send it if I want to search from, for example, Google. Do I send this: // "http://www.google.com/search?hl=en&lr=&ie=UTF8&oe=UTF8&q=race+%26+cars// I pasted the code above directly from the URL when I did a search at Google. Secondly, what data will the search engine return? For example, the search above came back with more than ten pages at Google. Will Google send back all pages or one page at a time? Please add if you have any experience dealing with search engines and/or communicating with websites in general. Thanks, Kuphryn Re: Search Engines :: Winsock Renjith Ramachandran17-Jun-02 15:10 Renjith Ramachandran 17-Jun-02 15:10  man, you can automate the process via microsoft Web Browser control... just accept the serch parameters from your GUI and searches through that..and show all the pages ..user will chose from which of them are want to print..

Custom Control On Toolbar Al_Pennyworth17-Jun-02 7:04 Al_Pennyworth 17-Jun-02 7:04  Hello, I have added a custom bitmap to the MS Word Toolbar to allow my application to save the information and exit MS Word. But I cannot find any document on what I need to do to figure out if my custom button has been pressed. Can anyone give any guidance on this? If the user presses my button, how will I know it? Things were going good up to this point... Re: Custom Control On Toolbar Ramu Pulipati17-Jun-02 7:44 Ramu Pulipati 17-Jun-02 7:44  Sink the button events(Office::_CommandBarButtonEvents) to handle the button clicks. Steps: 1. Inherit Add-in from IDispEventImpl<1, Office::_CommandBarButtonEvents> 2. Call (myCookie = ) DispEventAdvise(m_spButton) after button is created. 3. Implement Event Callback for OnClick - SINK_ENTRY(1, 1, OnClick) 4. Call DispEventUnadvise(myCookie) when button goes out of scope. check out similar outlook sample @ http://www.codeproject.com/com/outlookaddin.asp Hth, Ramu Minimizing app with task bar button Yuri Gershanov17-Jun-02 7:01 Yuri Gershanov 17-Jun-02 7:01  Hi everybody, Encountered a strange problem. When started, my application reacts properly on task bar events - it can be minimized by clicking on its task bar icon, and restored when the button is clicked again. But after I load a file into the app, the program will not minimize by task bar button, though the caption color changes to inactive. If I click on the caption, or use system menu to minimize the program, or just open the system menu, the normal behavior of task bar button is restored. Setting breakpoint in syscommand handler, I see that when the taskbar button is working correctly the program gets SC_MINIMIZE/SC_MAXIMIZE. After loading a file, it does not. Any idea on possible reason? Thanks, Yuri Re: Minimizing app with task bar button Ramu Pulipati17-Jun-02 7:59 Ramu Pulipati 17-Jun-02 7:59  If you are using MFC, make sure you are not dealing with taskbar icon in CMyDocument::OnNewDocument() or CMyDocument::OnCloseDocument() or CMyDocument::DeleteConetents(). Its better to handle taskbar add/remove operations in CWinApp derived class. Just some wild guesses Hth, Ramu Re: Minimizing app with task bar button Yuri Gershanov17-Jun-02 9:30 Yuri Gershanov 17-Jun-02 9:30  Ramu Pulipati wrote: If you are using MFC, make sure you are not dealing with taskbar icon in CMyDocument::OnNewDocument() or CMyDocument::OnCloseDocument() or CMyDocument::DeleteConetents(). Its better to handle taskbar add/remove operations in CWinApp derived class. I do not actually handle any of taskbar events explicitly, nor I use tray icons. This is just regular taskbar button that does not work... Thanks, Yuri Automatically open last opened document in SDI rrrado17-Jun-02 6:26 rrrado 17-Jun-02 6:26  Any idea, what is the best way to automatically implement opening last opened document in SDI ? 1. It's name is stored in registry under key ....\Recent File List\File1, but isn't there best way to get it from MFC ? ( i couldn't find any object's method for that) 2. where to place code for opening document ? CDocument::OnNewDocument() ? C..App::InitInstance() or somewhere esle ? How to open file in CDocument ? Thanks rrrado Re: Automatically open last opened document in SDI Ramu Pulipati17-Jun-02 8:30 Ramu Pulipati 17-Jun-02 8:30  Use InitInstance(), since this is the function which should be used for application startup. Replace 'ParseCommandLine(cmdInfo);' in CMyXXXApp::InitInstance with if(m_pRecentFileList->GetSize()) { cmdInfo.m_nShellCommand = CCommandLineInfo::FileOpen; cmdInfo.m_strFileName = (*m_pRecentFileList)[0]; } Do a include of afxadv.h at the top. Hth, Ramu Re: Automatically open last opened document in SDI rrrado17-Jun-02 23:04 rrrado 17-Jun-02 23:04  This seems to be good idea,thank you, i'll try this rrrado Re: Automatically open last opened document in SDI Renjith Ramachandran17-Jun-02 10:53 Renjith Ramachandran 17-Jun-02 10:53  it is better to keep the filepath in registry and open the file when u load the doument..try the streaming (CArchieve) Renjith-The CPian. Tree Control problem 17-Jun-02 6:14 17-Jun-02 6:14  I have a tree control that I create as following: m_TreeView.Create (WS_VISIBLE | WS_CHILD | TVS_HASLINES | TVS_LINESATROOT | TVS_HASBUTTONS | TVS_EDITLABELS | TVS_SHOWSELALWAYS | WS_HSCROLL | WS_VSCROLL | WS_BORDER , CRect (0, 0, nX1, nY1), this, 1001); m_treeview is offcourse derived from CTreeCtrl. However, when I try to edit a tree label, EditLabel returns a null handle which indicates that something is not right.. At first I thought it might be that my control is not editable, but it is obviously declared as editable. Any idea what the problem maybe?

R_Renjith The CPian Re: Finding all open application names RobJones17-Jun-02 5:26 RobJones 17-Jun-02 5:26  I would like to populate a combo box with the Names of all open applications, for example ("Yahoo! Messenger", "System Scan Status", "Virus Scan Console" etc....) I would like to see a list of every application (the window name) in the combo box not the .exe name.. Rob Re: Finding all open application names Ramu Pulipati17-Jun-02 5:40 Ramu Pulipati 17-Jun-02 5:40  I assume you doesnt mean enumerating process..??? To list all desktop windows, use the following code. HWND hWndNext = NULL; TCHAR szCaption[MAX_CAPTION_SIZE]; while((hWndNext = FindWindowEx(NULL, hWndNext, NULL, NULL)) != NULL) { memset(szCaption, 0, sizeof(szCaption)); GetWindowText(hWndNext, (LPTSTR) szCaption, (sizeof(szCaption) / sizeof(TCHAR))); //use szCaption here... } Check MSDN for detailed FindWindowEx API.

I don't recommend using the FindWindow function, because I've heard that it can get stuck in infinite loops. EnumWindow won't. Check MSDN for help on using EnumWindow.

Unfortunately it is much too long to post here. I'd recommend a search at the MSDN website. I Drowned Schroedinger's Stupid Cat!
