I suppose that you want to access the other class's member variables , isn't it ?

you can use the new operation.

This really depends on how the different classes are used in your program. One approach would be to pass Class_B to Class_A and provide getters in Class_B, so that Class_A can retrieve the values and populate the list.

What kind of architecure are you using ? Are you using MFC ? If yes are you using a doc/view architecture ? Is the list part of your view ? You need to give a lot more details about your architecture in order for us to help.

Hi...

I am using MFC only.
Its based on ObjectARX. I am retrieving all the values in Class_B.
But my list control is class_A.

How to insert class_B values in Class_A control?

So, what's wrong with my first suggestion ? Did you try to understand it at least ?

BTW, when somebody asks you for details about your program architecutre, repeating the same information you already posted in your first message doesn't add anything...

I am not sure what this has to do with C++, but ... If you are trying to do this with code then you will need to interpret the index of the PDF file, locate the data for the relevant page, and then format and display that data.

See the PDF specification documentation at Adobe[].

Hi All

I am creating database and then get database name and properties.Like this

QueryResultsPtr Qry;
DatabasesPtr spDatabases;
_SQLServer2Ptr spSQLServer;
Qry=spSQLServer->ExecuteWithResults((_bstr_t)"Create databse Testing",(LONG)"Create databse Testing".GetLength());
spDatabases = spSQLServer->Databases;
spDatabases->Refresh();

It's working fine.
But it's take too much time when cursor goes here

acessing source data on a URL

I'm a biochemist who needs to get some minimal bioinformatics done. I need a way to access data at a URL and do some simple manipulations. The program doesn’t need to be robust, it just needs to work. I'm looking for an easy way to access the info, copy it into a file, and move the next page.

I'm having a very hard time figuring out where to start here. I have very minimal coding experience. Any help is greatly appreciated.

You need to find a library that can request to a URL and return the response. POCO[^] has got a network library which can be used here.

why dont you look at 'curl' http://curl.haxx.se/[^]

- comes in a command line, windows version - you can 'get' pages/data etc, if you needed more I'm sure you could wrap scripting around it to for example dump pages/files to disk and parse them - or use the curl-library and drive it from a program

Can you elaborate? Are you wanting to download a file given its URL?

The site I need to access has a table of proteins featuring links to their sequence data. I need to be able to go from protein to protein, into the pages with their sequence data, get the data, and move to the next to one. I need to save all of this in a way that keeps the two in order.

The later end of that I can handle, even with my very basic skill set, I am used to manipulating data from text files. I'm just trying to figure out how to access the data.

Thanks to every for your help above, but I really do need help getting properly oriented. Every resource I find explains how to do this in terms of other things I don't understand. I'd really like to learn, but I need to know where to start.

again, i'm not looking for anything particularly robust, it just has to work.

http://www.ncbi.nlm.nih.gov/sites/entrez?Db=genome&Cmd=Retrieve&dopt=Protein+Table&list_uids=23523
Thats the page which lists all the genes I'm interested in.

from that I need to write a program that goes from each entry linked under the 'accession' column. For instance, for this homoserine kinase:
http://www.ncbi.nlm.nih.gov/protein/218698422

from that, I need the sequence of text under 'ORIGIN'

after that, I need it to loop through and check out all the others. I haven't worked out yet if i want it to kick all sequences it picks up indexed somewhere, or just perform the analysis I need, store that, and move on to the next one. I could write either, but it's a moot point if I can't get the data initially.

It doesn't seem like it should be to hard to do, but I need a push in the right direction.

Do you have direct access to the genome database? If not, the only solution I can think of would be to parse the obj_table23523 table that is being returned in the HTML.

WM_SHOWWINDOW[^] only notifies the given window that it is about to be hidden or shown, it doesn't actually hide or show the window.
