Re: Converting an icon into a bitmap Nicolas Bonamy14-Apr-03 1:30 Nicolas Bonamy 14-Apr-03 1:30  Does your stuff work? My code is just around 10 lines of code where I build a DC, select an empty bitmap into, draw the icon with DrawIconEx in DI_NORMAL mode and that's it. Do you do something similar? Re: Converting an icon into a bitmap Iain Clarke, Warrior Programmer14-Apr-03 0:49 Iain Clarke, Warrior Programmer 14-Apr-03 0:49  If you haven't already, you need to look at GetIconInfo. This function fills in a structure with two bitmap. One is the colour info, and one is the transparency map. The transparent part *should* be black on the colur bitmap, but you can separate it using the 2nd bitmap for reference. Iain. Re: Converting an icon into a bitmap Nicolas Bonamy14-Apr-03 1:28 Nicolas Bonamy 14-Apr-03 1:28  Iain, I saw this one and definitly wanted to take a look at it... Thanks for the infor. Regards Re: Converting an icon into a bitmap Nicolas Bonamy14-Apr-03 9:01 Nicolas Bonamy 14-Apr-03 9:01  Okay tested it but it appears that the bitmaps returned are wrong. Basically I get my icon from the system image list in where the icons are 32 bit with alpha. When I get them I get a 256 color version but the conversion is wrong: some parts of the mask that are gray become black where as in the icon the matching pixel gets black also. So I get black. What I need now is to force the extraction in 256 colors. The problem is that I get a handle to an icon in the system image list and I do not know where this icon is located on disk so I can't really extract it from the .ico file. Anyone? Sending text as popup message Mr Bose Dayala14-Apr-03 0:17 Mr Bose Dayala 14-Apr-03 0:17  Hi, can anybody let me know how to send a text just like popup message to another system(by selecting the username from dropdown box) in LAN through program. thanx in advance Thomas. ThomasKennedyBose Re: Sending text as popup message cr9714-Apr-03 4:07 cr97 14-Apr-03 4:07  I don't know special api-calls for this ... but maybe you can use the Windows command "net send" ??? (translated from a german windows ...) NET SEND {Name|*|/DOMAIN[:Name]|/USERS} Message<br /> Example: NET SEND ThomasBoseKenn "Do you need further help ?" cr97 Re: Sending text as popup message Mr Bose Dayala14-Apr-03 18:01 Mr Bose Dayala 14-Apr-03 18:01  thanx...but it should be done through programatically...slect an user name from the dropdown box which displays all the users in one domain,when we click on "Send" button ,string in the edit box should be sent to that user just like a winpopup message(just like NET SEND cr97 "Ya..I need your help?" command works).... BR Thomas ThomasKennedyBose Re: Sending text as popup message cr9714-Apr-03 22:24 cr97 14-Apr-03 22:24  And why don't you make a dialog, where the you can select the text and the user ??? And after pressing "SEND" you concatenate all the strings like <br /> strCall = "NET SEND "+strUserName+" \""+strMessage+"\"";<br /> then you can execute "strCall" ... is it a solution for you ? cr97 P.S. Sprichst du deutsch ? Re: Sending text as popup message Mr Bose Dayala14-Apr-03 22:39 Mr Bose Dayala 14-Apr-03 22:39  ya....I have already done that code.....any how I don't leave you ..now you tell me how to get the machine name(like "\\mdpworkstn64")by selecting the username....any APIs?? BR Thomas ThomasKennedyBose Re: Sending text as popup message cr9714-Apr-03 23:00 cr97 14-Apr-03 23:00  IMHO if you have the user name it is not necessary to know the machine name ... cr97 Re: Sending text as popup message Mr Bose Dayala14-Apr-03 23:42 Mr Bose Dayala 14-Apr-03 23:42  ok ..ok ....sorry for that scenario...actually what I want is I will give the machine number(or name like //mdpwksrnd64)and I want to get the user name who has logged in to that machine...is it possible?? ThomasKennedyBose Re: Sending text as popup message cr9715-Apr-03 0:05 cr97 15-Apr-03 0:05  At moment i don't know if this s possible but i think so ... why do you wanna know who is logged in at a special machine ??? cr97 Re: Sending text as popup message Mr Bose Dayala15-Apr-03 0:42 Mr Bose Dayala 15-Apr-03 0:42  suppose I want to send personal message to my friend who is supposed to be on that machine...but unfortunately some other person logs in....!!!!in that case first I will check for the logged in user by giving the machine name....hope you can understand the situation.. ThomasKennedyBose Re: Sending text as popup message cr9715-Apr-03 1:42 cr97 15-Apr-03 1:42  You can try to send the message to the user ... NET SEND bob "Hi ... are you online ?" This sends the message not to a machine but to a user in the network ! In this case it doesn't matter on which machine "bob" is logged in. Try it at the DOS-Prompt ... cr97 Re: Sending text as popup message Mr Bose Dayala15-Apr-03 1:47 Mr Bose Dayala 15-Apr-03 1:47  )))))) ok ....leave this scenario...I just want to know who has logged in on a perticular machine(I know the machine name)....then how it is possible through program?? ThomasKennedyBose Re: Sending text as popup message cr9715-Apr-03 2:13 cr97 15-Apr-03 2:13  Good question ... ähm ... next one ... Therefore at the moment i don't know a solution ... maybe you find something in the "google groups" ??? cr97 Re: Sending text as popup message Zdeslav Vojkovic14-Apr-03 4:14 Zdeslav Vojkovic 14-Apr-03 4:14  older applications like PopUp utility on Win95 use mailslots (Popup creates mailslot named "messngr", and periodically checks if there are new messages in mailslot. when sending messages, it simply writes to messngr mailslot on another machine) you can also use messenger service on Win2K and later, but i never used that, so i can't go into details (this is what is used when you issue a command like "net send <machine> hi" at command prompt).

Joaquín M López Muñoz13-Apr-03 22:51 Joaquín M López Muñoz 13-Apr-03 22:51  Don't know if the best, but it is damn good anyway: Crypto++[^] comes with lots of docs and samples, it is totally free and suffers from none of the export restrictions applicable in the US. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo component creation in C++ pankajdaga13-Apr-03 22:47 pankajdaga 13-Apr-03 22:47  Hi everyone, I am looking for a tutorial that discusses GUI component creation in C++ and packaging it as DLL. Can anyone with some experience point me to a good website or recommend a good book for this. Thanks, Sincerely, Pankaj Without struggle, there is no progress Re: component creation in C++ valikac14-Apr-03 7:50 valikac 14-Apr-03 7:50  Do you want a normal MFC DLL or a COM component? For MFC DLL, here is one good resource. http://www.mindcracker.com/mindcracker/c_cafe/dll.asp Kuphryn Re: component creation in C++ pankajdaga14-Apr-03 22:16 pankajdaga 14-Apr-03 22:16  Hi, Actually I was looking for a DLL that does not use MFC. Do you know any such component DLL examples? Thanks for your reply. Sincerely, Pankaj Without struggle, there is no progress
