Thanks for your infomation, Luc. I'm using your approach, and it works fine. I just got another question, if the PC is a remote server that different user may login to the server and launching the same application. May I use the same function to detect what specific user is launing the application ? thanks

Hi All, I would like to know, how can I detect whether an application is already launched? I need to enable some function according to this checking, can some people help? thanks so much.

thanks for your reply, Abhinav However, I'm not generate a checksum from a file stream. firstly, i get a combination string from the parameters and by the formula I will get string org_str = "JOHN_C2182_20102009" I need a method to generate a checksum string from the above "org_str" do you have other example? thanks

Hi all, I need to generate a check sum string from visual basic and pass to a Java implemented class according to the specification. the requirement from user spec is saying that the check sum string should base on the following formula. e.g. (Username + UserId + Transaction Amount + Transaction Date). suppose I have the above parameters, but how can I generate the MD5 checksum string from VB? can you provide an example? is it using Security.Cryptography.MD5CryptoServiceProvider ? P.S. I need to genereate the checksum as a STRING. thanks

Dear All, I have a question about joining 2 table. e.g. table1 contains user---inv---amount---data2 a --- 001--- 1000 --- dfsdf st --- 001--- 1200 --- sdfs b --- 002--- 1300 --- sdf c --- 004--- 1400 --- sdf e.g. table2 contains cid--- data--- FromCountry 001--- acd--- USA 001--- efg --- USA 001--- okk --- USA 002--- cce --- CHI 003--- eer --- UK 003--- err --- UK 004--- edr --- VOC I would like to construct a table base on table1, and include the field "FromCountry" from table2. I use select table1.user, table1.inv, table2.FromCountry From table1, table2, Where table1.inv = table2.cid when joining 2 table, I found there are duplicated records generated... How can I just get the "FromCountry" from any one of "cid" record in table2? The perfer result on new table is: user --- inv --- FromCountry a --- 001 --- USA st --- 001 --- USA b --- 002 --- CHI c --- 004 --- VOC PLEASE HELP

however, I can't initialize the array like this: LPTSTR[] files = new LPTSTR[count]; do you mean copy character by: LPTSTR a = list.GetAt(0).CopyChars?

sorry, what do you mean "copy all the strings. "? can you provide me a code? thanks

sorry that I can't change the interface for function "GetNewXML", coz it has been written by pervious staff. so I trying to do, but not work /* LPTSTR[] files = new LPTSTR[count]; for(int i=0; i< count ; i++) { files[i] = bmpList.GetAt(i).GetBuffer(); } */

Hi , I have a CStringList that contains some filepaths, these paths need to be passed into a function: eg: GetNewXML(LPTSTR PreviewFileArray[],int count) How can I construct a LPTSTR array from CStringList? thanks

Would you mind provide me a sample code for creating a bitmap. I've read some doc, it needs to create Bitmap header as well... actually, the raw data (image from char* ) must eventually save into Png file, so I want to save it to Bitmap first, and then convert to png.

Hi, this maybe a stupid question. But I'm new to C++ I would like to create a bitmap, and put data from by myself i.e. I have to process a set of pixel data from data buffer, after the calculation, I would like to save the data into a Bitmap. maybe line by line, maybe append from a loop. Can anyone provide me an example for saving and creating bitmap? many Thanks..

Thanks for you reply. Can you provide me a sample code for converting Lab value to RGB value? I've read some documents, they said the step should 1. convert Lab -> XYZ 2. convert XYZ -> RGB I don't know how to write such calculations.

Can someone share me some example programe code for this? I need it urgently... >_<

Hi all, I have to make a library to convert the Color from Lab value to RGB value. However, it requires an algorithms to do so. I read some documents, it mentioned that the steps should be 1. Lab -> XYZ 2. XYZ -> RGB I really have no idea what the calculation should be. I hope to fine some example from here, as I think some of the experts must have done the same things, or have this experience. Could you please provide me some examples? Thanks Thanks ...

Actually, I'm a beginner in writting Graphic related program. especially in C++. I have no idea on the calculation for processing & converting the LAB to RGB. So I hope to find some examples with codings that I can easily to learn and understand . Could you provide me some program examples if you have this experience. Thanks a lot.

Hi all, I have to make a library to convert the Color from Lab value to RGB value. However, I have no much idea on the calculations or algorithms. Suppose I will receive a data (Char pointer) then convert to RGB. Can some of you give me some hints or examples? Please Please... I believed that this should be easy for some experts. Thanks for your help..

Thanks so much PIEBALDconsult ~

Hi, I'm doing a printing range option, allow user type the print range like in the Microsoft Word. for example, the range can be (1,2,4-8,10-12) now, I would like to do a validation, prevent any non-useful character inside this string (i.e. except digit, "," and "-") any faster way to do this? Thanks for your help.

Hi all, I just want to have a feature to reverse the order of some of my selected ListViewItems. for example, I would like to reverse the order of Items50 - Items 100 only. Does anyone know the simple way to do this? Thanks.

Hi Friends, I got a strange question on my application. Sometimes when I going to start my application, a installer will appear, and asking for reinsall. After reinstalled, the application can be run. It was not happened everytimes, but very occasionally. I'm thinking what's wrong in my project design? 1. will it related to the problem of some missing folder? (coz I set all folder AlwaysCreate to true) 2. any wrong step I made on my installer? My project is related to PDF, is it related to PDF problem? Please help, and give some hints. Thanks so much
