I want to built a DLL in which we can pass parameters to call a jar file and the return values of the Jar file should be available to the calling application. Do anyone know How to perform this ? Thanks in advance. Nikhs Nikhil Trivedi

Sorry that I got your question wrong. I havent worked on office tools, but one of my friend who worked on this told me that he was using excel.h then. I dont know if it might help you or not. Nikhs Nikhil Trivedi

how do I open an existing XLS file

I think the ShellApi.h would be of your help. You can get its detail from msdn.com. I think the ShellExecute() function will do for you. Hope this would help you.

Dear friend, I think Shellapi.h might be of your help. Once I used it to open an text and excel file. Dont know specific functions right now. ShellExecute() will help. I think. Nikhs Nikhil Trivedi

Got it. Thanks to remind me about that. Can you help me how can i send a java command to command prompt through visual c++. I want to unpack a jar file which can be done from command prompt by passing a command like : java -jar C:\myfile.jar para Appreciate your advice. Nikhs Nikhil Trivedi

I didn't get the point you raised. Can you explain me that with some example ? Thanks for your reply. Nikhs Nikhil Trivedi

It didn't work. When I use debuger, it shows me the return value of the shellexecute as 2 and the value for getlasterror is the same. I dont knokw how to deal this ? I am using the following code snippet : HINSTANCE hInst; hInst= ShellExecute(NULL,reinterpret_cast("open"),reinterpret_cast("C:\j2sdk1.4.2_12\bin\java.exe"),reinterpret_cast("-jar C:\psae.jar WORLD"),NULL,SW_SHOWMAXIMIZED); and even try with this one : hInst= ShellExecute(NULL,reinterpret_cast("java"),reinterpret_cast("C:\j2sdk1.4.2_12\bin\java.exe"),reinterpret_cast("-jar C:\psae.jar WORLD"),NULL,SW_SHOWMAXIMIZED); both shows the same error. Error no. 2.

Thanks Dear friend. It really will help a lot. Nikhs Nikhil Trivedi

I dont wanna call c++ function from java but wanna call jar file from visual c++. BTW, thank you for your reply. Nikhs Nikhil Trivedi

This might be a bit helpful. Can you send me a sample code say I want to call a jar file at location C:\psae.jar with the parameter "world" then the syntax from command prompt is : java -jar C:\psae.jar world How the command string should look like for this one ? Thanks for your reply Nikhs Nikhil Trivedi

Thanks for your reply. But actually I used the netsend command for example purpose only. I want to use some commands like cd directory, cd.., and run some .exe from console. Can you help me in that ? Thanks for your prompt reply. Nikhs Nikhil Trivedi

Dear all, Can anyone tell me if there is any API for accessing command prompt and get the result of the command back to the application ? Thanks for your prompt reply. Nikhs Nikhil Trivedi

Hello dear friend, I am successful in calling the function with passing values as reference but when I access the values in calling application which is out side of the c++ environement, I am getting those as NULL. Can you tell me the reason. Nikhs Nikhil Trivedi
