Re: btrees in STL valikac10-Jul-03 7:48 valikac 10-Jul-03 7:48  Are you referring to a binary tree structure? If yes, STL containers including set and map are designed using binary stree structure. Kuphryn Re: btrees in STL David Crow10-Jul-03 8:58 David Crow 10-Jul-03 8:58  By btree, do you mean a binary tree, which can be lopsided, or a B-tree, which is always balanced? Re: btrees in STL Anonymous10-Jul-03 12:24 Anonymous 10-Jul-03 12:24  a balanced tree that is. however, any kind of a tree I guess wouldn't be bad. Anything like CTreeCtrl in MFC even? Re: btrees in STL David Crow11-Jul-03 3:08 David Crow 11-Jul-03 3:08  B-tree, red/black tree, splay tree, and AVL tree are all examples of balanced trees, each with their own set of nuances. The CTreeCtrl class is for displaying a hierarchical list of items, much like Windows Explorer.

I want to enable the user to have the ability to delete, change or add a new number into the array. What would be my best approach to do this? Thanks much, Dave ------------------------------------------------------------------- #include "iostream.h" #include "string.h" int main() { int x; int i; char str[80]; bool isfinished=false; char Info [] [300] = { "6787-02-000-5287" , "Here is the information for this number." , "5978-03-000-0029" , "Here is the information for this number." , }; while(isfinished==false) { cout<<"\nPlease enter a number:\n"; cin>>str; for(i=0; i < 4; i += 2) if(!strcmp(str, Info[i])) { cout<<"\nInformation:"<<info[i+1]<<"\n"; break;="" }="" if(i="=" 4)="" {="" cout<<"number="" not="" found.\n";="" cout<<"\nwould="" you="" like="" to="" check="" another?\n";="" {="" cout<<"enter="" 1="" for="" yes,="" 0="" no.\n";="" (cin="">>x).get(); } if (x==0) isfinished=true; } return 0; } Re: input/change/delete array elements valikac10-Jul-03 7:49 valikac 10-Jul-03 7:49  One solution is and STL list container. Kuphryn Re: input/change/delete array elements David Crow10-Jul-03 9:06 David Crow 10-Jul-03 9:06  It depends on what you are after. As I understand it, you'd want a simply menu like: CHOICES ---------- 1. Display 2. Delete 3. Change 4. Add If the user chose #1, you'd print the current contents of the array using code similar to what you've shown. If the user chose #2, you'd prompt for the array index to delete. All items in the array after that index would probably need to be moved "up" in the order to fill in the hole. If the user chose #3, you'd again prompt for: 1) the array index, 2) the part number, and 3) the part number description. The array item at the specified index would then be updated with these new values. If the user chose #4, you'd prompt for the part number and the part number description. These values would then be assigned to the next available index. Re: input/change/delete array elements DaveE9th10-Jul-03 22:05 DaveE9th 10-Jul-03 22:05  I'll read up some more on arrays and the STL list container and maybe something will start smokin' up in my attic. Thanks, Dave How do you save work or settings with a dialog in a diffrent file and opening it? Snyp10-Jul-03 7:23 Snyp 10-Jul-03 7:23  ¿ANYONE?

Re: How do you save work or settings with a dialog in a diffrent file and opening it? valikac10-Jul-03 7:50 valikac 10-Jul-03 7:50  What kind of settings? Kuphryn Re: How do you save work or settings with a dialog in a diffrent file and opening it? Snyp10-Jul-03 16:58 Snyp 10-Jul-03 16:58  as i said in a dialog..

Re: How do you save work or settings with a dialog in a diffrent file and opening it? Terry O'Nolley10-Jul-03 8:58 Terry O'Nolley 10-Jul-03 8:58  Your question was really quite open-ended, but I'll stir the tea leaves around and assume you are asking about saving the contents of various dialog box controls to a disk file that can later be opened to return that dialog box to it's saved state. To do this, just create a data struct that has holders for all variables that are required to hold the dialog box data. do a binary write of that data struct to disk. Or create a class and serialize it to disk. I'm going to live forever or die trying! How do you populate a combobox from a remote datasource? Terry O'Nolley10-Jul-03 7:17 Terry O'Nolley 10-Jul-03 7:17  I've blown up this project 4 times by adding all sorts of ActiveX components that I thought would allow me to populate a combobox from a remote datasource but nothing worked. I have currently kluged a solution that is so horrific I shudder whenever I see it. My workaround is to create an InternetSession, send an HTTP request to a cold fusion page on my webserver that queries the database and the output is sent back to the buffer that is filled by the CHttpFile* read operation. I then use character parsing to search for the field delimiters and move the parsed strings into the combobox. UGLY!!!!!!!!! For the ActiveX controls I dropped into the project I can't even get a compile. I see vague mention of my needing to create a wrapper class and yada yada. Is there a prebuilt C++ class that I can just include in my project that will allow me to specify the IP address or name of my server, the ODBC DSN, the SQL query and the Combobox ID and have it populate it for me? I have successfully added a great directory tree and the Victor Image Library into my project and it all works great, but I need to dynamically populate those comboboxes from a remote datasource. PLEASE HELP!!!!!!!! I'm going to live forever or die trying! Re: How do you populate a combobox from a remote datasource? David Crow10-Jul-03 9:08 David Crow 10-Jul-03 9:08  Does your database support ODBC? Re: How do you populate a combobox from a remote datasource? Terry O'Nolley10-Jul-03 10:07 Terry O'Nolley 10-Jul-03 10:07  The DB is already mapped as a system DSN on the webserver and is working fine with ODBC. BTW - The server is running NT server 4 Re: How do you populate a combobox from a remote datasource? David Crow10-Jul-03 10:30 David Crow 10-Jul-03 10:30  Then you should be able to create a DSN on your application's machine that "points to" the DB on the Web server. I did this once where a SQL database was on one machine and my client application and DSN were on another machine. Worked fine. Re: How do you populate a combobox from a remote datasource? Terry O'Nolley10-Jul-03 10:37 Terry O'Nolley 10-Jul-03 10:37  I had no idea that remote connections with ODBC were possible! I am OK with SQL the language, but very weak on the DB admin side and had no idea that you could map a remote DSN using ODBC administrator. I went through all of the options in my ODBC administrator and nowhere does it ask me about the IP address for the remote server. Is there a different ODBC admin tool I need to install first? Dll and PreTranslateMessage Daishy10-Jul-03 7:11 Daishy 10-Jul-03 7:11  Hi, I've written a small Winampplugin. Now i Want to catch the Keymessages. I've tried to this by editing the Pretranslatemessage function, but it never gets any messages...what to do now`? Thanks for your help MS Visual C++ 6.0 problem djordj10-Jul-03 5:16 djordj 10-Jul-03 5:16  I've lost a class!!! I've got CMyClass.cpp and CMyClass.h included in the project. I've got CMyClass working in ClassWizard. BUT I can't find CMyClass in the left pane of the work area, where I usually have all my classes listed in a tree structure. What can I do? Re: MS Visual C++ 6.0 problem John M. Drescher10-Jul-03 5:18 John M. Drescher 10-Jul-03 5:18  Close visual studio and delete the .ncb file and then reopen the workspace. John Re: MS Visual C++ 6.0 problem Joan M10-Jul-03 7:15 Joan M 10-Jul-03 7:15  Easier and faster... modify your header file and re-save it (add a space and delete it again or something like this)... this normally does the trick... Hope this helps... Re: MS Visual C++ 6.0 problem djordj10-Jul-03 21:17 djordj 10-Jul-03 21:17  Ok, done! Thanks!
