Letters in a matrix? nywebhead15-May-02 9:01 nywebhead 15-May-02 9:01  How do you put letters in a matrix instead of numbers? Char? Will it be able to convert to int? Re: Letters in a matrix? Joaquín M López Muñoz15-May-02 9:06 Joaquín M López Muñoz 15-May-02 9:06  Yes, an array of chars is fine to store letters. The conversion of chars to their numerical equivalents is done automatically like this: char ch='A'; int i=ch; //i==65, the ASCII code for 'A' Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: Letters in a matrix? nywebhead15-May-02 15:43 nywebhead 15-May-02 15:43  Thanks. Linker error for /delayload with VC 6 Cristina197615-May-02 8:27 Cristina1976 15-May-02 8:27  I have tried to use the /delayload linker switch for the VC++ 6, but I've got error LNK2001: unresolved external symbol __tailMerge_ when trying to delayload more then one dll. To be more precise: -I want to create test.dll that links against dll1.dll and dll2.dll -dll2 is also linked against dll1 -trying to delayload both dll1 and dll2, I've got the above mentioned linker error for dll1 I would appreciate any solution or explanation why this happens.

JoeSox15-May-02 7:49 JoeSox 15-May-02 7:49  How do I get information from a dropdown menu (from html page in CHtmlView) to a variable in my c++ application?? I have searched all over and need some help. (Developing in MSC++6.0 sp5 & IE6.0) Re: CHtmlView Question... Paul M Watt15-May-02 8:06 Paul M Watt 15-May-02 8:06  Hopefully you are comfortable with COM because this requires you to do a lot of interface navigation. You will need to dig down into the HTMLDom and access the particaly HTML Element that you are interested in. The basic idea is to start with the IWebBrowser2 itnerface from your CHtmlView, then get the IHTMLDocument from the browser interface. Next cycle through all of the Child elements until you find the menu you are interested in. Once you have that you should be able to access the elements of that menu for the data you are interested in. Good Luck!

Matt Gullett15-May-02 8:43 Matt Gullett 15-May-02 8:43  The basic way to do this is to use the COM interface exposed by the WebBrowser control and find the element you are interested in and interogate its properties. Another way this can be done is to have an onchange event for the drop down that redirects to a URL like customstuff:myvar=1 type of thing. Then in your CHtmlView class you can overide the OnBeforeNavigate2 (maybe OnBeforeNavigate??) function and check for the customstuff: prefix and set your variable accordingly. Remember to cancel the navigate, of course. Another way is to use the wonderful DHTML UI library provided by Ted Crow. (http://www.codeproject.com/useritems/dhtmlui.asp). This library will allow you to expose your applications object model to the HTML windows being displayed though the window.external property. What would be the best solution for storing a large amount of paths? redeemer15-May-02 7:32 redeemer 15-May-02 7:32  I have a program that i want to organize mp3's with. But, i've come to a place where i need to store a path for every item in a ListView control, so when i add some new items to the list, the pathlist gets larger and i can retrieve the path somehow. What would be the best solution? Thanks Re: What would be the best solution for storing a large amount of paths? Paul M Watt15-May-02 7:50 Paul M Watt 15-May-02 7:50  Are you talking about retrieving the path pragmatically in your program, or visually to the user. If you are talking about pragmatically, have you tried associating the data with each element in your list view? You can either just associate the path string with each item, or you could create a structure that contains any amount of data that you want and set the pointer to the structure in teh user data of the list view item.

I have designed the app in a resource file but i add items via api's. ANd also, i don't want that value to be a visible item, jsut somethingi can retrieve when i want to. Re: How do i assign a path to each item? Paul M Watt15-May-02 8:35 Paul M Watt 15-May-02 8:35  If you are using the Win32 API, then you will simply update the LVITEM structure that you have used to set into the list view. You can set the lParam parameters of this structure. Build a man a fire, and he will be warm for a day Light a man on fire, and he will be warm for the rest of his life!

Paul M Watt15-May-02 8:02 Paul M Watt 15-May-02 8:02  You still have access to the synchronization functions like WaitForSingleObject. So if there is some sort of event that you can set to wake up your thread that would be the best solution. The types of objects you can use are: Change notification Console input Event Job Mutex Process Semaphore Thread Waitable timer You can also set a timeout value so that your thread wakes up automatically if the timeout expires. Just remember to include Windows.h if you want to go this route. Or you could simply tell your program to sleep, but that still takes up a lot of processing power depending on how long you tell your app to sleep. Good Luck!

How do I change the menu font to make it the same or larger than the dialog windows? Thanks! Re: popup menu font sizing Paul M Watt15-May-02 8:12 Paul M Watt 15-May-02 8:12  The font of the menu is determined by the system settings, and the actual menu window is as system window, so there is no way to simply set the font of a menu short of changing the systems settings. Therefore you will have to create an owner drawn menu in order to get the font to appear the way that you want. Another possible way to do this is to create bitmaps at runtime when your dialog is created that contian the font and the size of the menu that you want, and assign these bitmaps to the menu. That way you only need to do a little bit of setup work when you window is created rather than getting into the messy owner drawn menus. I think this would be the easiest solution, and there is an example in Charles Petzolds Programming Windows book. Good Luck!

Only if WTL had AfxGetMainWnd Mike.NET15-May-02 7:13 Mike.NET 15-May-02 7:13  In MFC there is an easy to get access to CMainFrame and call its methods from anywhere in the application. Just by simply doing this... CMainFrame pFrame = (CMainFrame*)AfxGetMainWnd(); pFrame->MyFunction(...); Although in WTL there is method GetTopLevelWindow() that can be used to get access to Top Application Window, but there seems to be no way to cast the return CWindow type to CMainFrame. Take for instance the following... CMainFrame frm = (CMainFrame)GetTopLevelWindow(); frm.MyFunction(...); ... will not work, as there seems to be no way to cast ATL::CWindow to CMainFrame. THE QUESTION!! How would one go about calling CMainFrame method from anywhere in the WTL application (say from distant dialog box)? Without using global variable to store pointer to CMainFrame? Is there such way? Or am I just dreaming Thanks in advance Mike M
