Thanks for your reply... at last some one is hearing me ! Well.. I am developing a tool which is very internal to our office.. a web access to one of the hardware which is connected to com port. Got a jar file with the hardware which shall be used to connect the hardware through comport. I dont have the source of the jar file. So, i am not worrying about the security and whether it is feasible etc. I would appreciate if some one can give the solution.. for the problem i posted. There is some guy who developed hardware is giving the jar file.. think he had lot of trust with Java language growth!

Is it possible to call a method of jar file which is residing in Client side, through java script. this is required to access USB port for testing tool development. Here is give a simple example to help me with code snippet. A simple Java program (simple.java) which has two methods GetName() and GetID() which returns string and integer value respectively. which is then converted to jar(simple.jar) and placed in C:\Temp\simple.jar. Can some one help me in java script code snippet, how to call the jar file inside my html file, and how to access the GetName() and GetID() method. Note: Simple.jar file will be at client machine and NOT at server side, may be i have to learn how to use plugin to download simple.jar from server to client (will be happy if i get some pointers on this too!) FYI, I am newbie to javascript.

I am emulating mobile in windows platform.. so I have two text box emulating 2 lines of LCD of mobile. Max number of character that i can store in memory can be 50 per line, but the only 20 characters can be displayed in LCD(text box) at any point of time. I have to take of scrolling left, scrolling right, including insertion and deletion of character in LCD(text box) I know i have to take of Cursor position, and possibly have MasterBuffer which will contain the 50 characters and TemporaryBuffer which shall contain 20 characters to display. I can work out a logic to take care of insertion, deletion etc. But before i start doing my own logic, i wish to know is there any algorithm defined for it already as or any library available or any kind of class.. or code snippet.. i dont want to start from ground zero if it is already something is available.. as i felt text editing in mobile is common.. Let me know if you want more info.. Advance thanks on your reply!

I am using watch window. I created new project (windows console application) and added the file to it and same code is working!!! I think some problem with the Windows Forms Aplication. problem with IDE ?!

Thanks to all, memset problem is solved, i could see the structure is set with 0. sakthii wrote: Problem no: #3: I see 13 is getting updated in myEntry[1].resevered1 variable... Even though you are not assigning anything to it? No. it happens when I am assigning the value to other parameter like myEntry[1].length= 4 How are you verifying the values? verifying using step by step debugging, I am using Visual Studio 8.

I created a form application File->New->Project->VC++->Windows Form Application. I created couple of .Cpp files and .h files. I have structure defined in .h file typedef struct _PHB_ENTRY { unsigned char name[30]; unsigned char add[50]; int checksum; int lenght; int reserverd1; int reserved2; } PHB_ENTRY; I have declared a variable in .cpp file, which is nothing but a 'C' code. PHB_ENTRY myEntry[50]; First i have init function, thought to initialize the struc with null, so i used memset memset(myEntry,NULL,50); Problem no #1: I cant see index 0 is intialized to NULL ! then i started initializing the struct strcpy((char*)myEntry[1].name,"STEFY"); Probmelem no #2: I can see STEFY being copied from myEntry[1].name[4], first for bytes are empty , that is myEntry[1].name[0]...myEntry[1].name[3] are empty!! i assigned other values. myEntry[1].checksum = 13; myEntry[2].length = 4; Problem no: #3: I see 13 is getting updated in myEntry[1].resevered1 variable and i cant see myEntry[2].length getting updated! can some one help me out on this strange problem?! Just a simple C code though!!!

Thanks for your reply. I posted this query after searching through net and going through codeproject. There are many features available for WindowsCE! I am working on WindowsForms. I am hardcore C Programmer, I am introduced to C++ because of MFC/Visual Studio to create gui to my back end C program library. I am switching over from MFC to windows forms as i am informed that WF is easy than MFC. I am learning Windows Form now, and i see examples for VB, C# and C++. I prefer to use C++ as i can manage and understand the same compare to other. I created Windows Forms project using following options: File->New->Project->VC++(main option)->Windows Forms Application in Visual Studio 2008 professional edition. I really dont know whether C# or C++ is used by default by the VS2008 while creating the template! I looked into this site http://msdn.microsoft.com/en-us/library/system.windows.forms.cursor(VS.71).aspx my requirement is I wish to change the cursor based on button press inside the text control and back to default on clicking another button. I used following code. private: System::Void button4_Click(System::Object^ sender, System::EventArgs^ e) { // creating new cursor System::Windows::Forms::Cursor= gcnew System::Windows::Forms::Cursor("MyCur.cur"); // this should set a cursor for all TextBox inside the form System::Windows::Forms::TextBox::Cursor::set(mycur); //setting the focus to textBox1 textBox1->Focus(); } // to get default cursor private: System::Void button5_Click(System::Object^ sender, System::EventArgs^ e) { System::Windows::Forms::Cursor::Current = System::Windows::Forms::Cursors::Default; } Result: on button4 press, the whole form gets the new cursor. And the focus given to textBox1, with default cursor! on button5 press, it is not reverting back to default cursor.

I am not getting you henry!

I like to simulate Mobile UI using Windows Forms. I want some pointer to implement following features, 1. How to display cursor(horizontal cursor "_" and vertical cursor "|") inside text box control 2. How to get cursor position and move the cursor. Some one can also suggest whether TextBox control is enough for the above implementation or whether i should go with RichTextBox control thanks

like to know how to display TIFF image in Windows Forms. I am using Visual Studio 8. Created Project using VC++ -> WindowsFormsApplication

Thanks for your reply. I will try.

I am using Visual Studio 8. I created two win32 empty project and created C "Mylib.c" "MyWrapperlib.c" file to get static library Mylib.lib and MyWrapperlib.lib. I created another win32 empty project and when i link the static library "MyWrapperlib.lib" (with Mylib.lib and MyWrapperlib.lib in library path) with simple C code "TestApp.C" with main(), it is working fine. I have used windows.h in "Mylib.c" and "MyWrapperlib.c" for FILE operations. I want to have a GUI application, so I created NewProject->CLR->Windows Forms Application (MyUIApp.Cpp). When i used MyWrapperlib.lib, it gave linking error. so I created DLL for MyWrapperlib.c by using #define dllexport __declspec(dllexport) enclosing with extern C When i use MyWrapper.dll in MyUIApp.Cpp, it is giving below error "fatal error LNK1107: invalid or corrupt file: cannot read at 0x2B0" Can some guide me how to create 'C' lib/dll and use it with GUI application.
