C Sharp :: How To Display Urdu Unicode Characters On Windows Forms
Aug 3, 2012
I tried to get the Urdu Fonts from MySql Database using C# in Visual Studio 2010 in Windows Forms Application. When I get the value from table into my variable it shows the characters in ???? symbols. But in PHP i have used the following code:
<?php
class CRUD {
var $con;
//function to make connection to database
I'm trying to port a Win32 application over to Windows Forms so that I can have better graphical control over the interface. The program itself is pretty simple; in the main message loop it listens for a WM_CopyData containing a certain char array, and occasionally sends WM_CopyData itself after the user clicks a certain sequence of buttons.
I found a couple of pages discussing how to completely override the Windows Forms WndProc, but I rather like having the framework do all of the control and would prefer to only latch onto it, rather than replace it. So, what would be the best way to have a Win Forms application listen for Windows Messages continuously and execute a function upon receiving them?
If I do need to override WndProc, what is the syntax? I found the following code:
Code:
protected override void WndProc(ref Message m) { base.WndProc (ref m); if (m.Msg==0x4a) // WM_COPYDATA { // do your stuff here... } }
But when I stick that into my main.cpp file right after int main function, "protected" gets highlighted as a syntax error with the message "IntelliSense: expected a declaration".
I'm trying to have a button marked by the sqrt sign, '√'.
I wrote below code and typed that sign by holding down "alt" and typing 251 using numpad. But result is the question mark instead of sqrt mark!
My machine is Windows 7 x86 and IDE is visual studio 2012.
#include <GUI.h> using namespace Graph_lib; //--------------------------------- class Test : public Window { public: Test(Point, int, int, const string&);
I'm having some problems in receiving fileNames from Server to Client(C++) in Mac OS X. I send a serialized object , which has a char pointer with the fileName or sometimes a string object, when i receive it in the client, it seems to be having %F6 or %E9 ,etc . This issue don't arise in Windows OS though, even thought it's the same code. Is there anyway decoding these '%' characters back to their original form in Mac OS & Linux ..?
Fex characters i got into problems with : ǡ ȅ ȉ
It would be difficult to change the code in server, so if there's a way decoding the characters back to its original form, it would be easier.I'm using Boost Library for Serialization and i'm just looking for ways to decode %F6 back to ȅ in C++, like if some library is available ..?
What I'm doing is giving the user the choice to show 2 different dates. 1 in yyyy-mm-dd notation and the other in dd-mm-yyyy notation.
I'm using a second form to do this.
So from Form1 I have my data in the datagrid and in Form2 I have 2 radio buttons giving the user the choice between Date1 and Date2. So how would I be able to interact with the first form with the radio buttons?
I'm trying to print Chinese/unicode characters to a line printer(EPSON LQ-2090) using the writePrinter method in c++.
ANSI characters print fine, but when I throw the buffer of widechar Chinese characters at it, they come out like garbage/ANSI chars.
while debuging string shows chinese characters but in memory it shows ANSI characters not chinese and these ANSI characters are get printed on printer.
Note that if I change the DocInfo datatype parameter to "TEXT" instead of "RAW" then also the Chinese characters donot print.
Is there a way to get Chinese or unicode characters to print correctly?
I made 2 forms and Form2 has buttons with images like planets and game wallpapers etc. When I write the code for button:
this.BackgroundImage = new Bitmap(Properties.Resources._8_8008_by_amplifier404); this.BackgroundImageLayout = ImageLayout.Stretch;
// where _8_8008_by_amplifier404 is name of the image located in resources
It only changes background in form which has those buttons as long the form is used. Once I go back to form1 it's changed to null. How to set background in all forms with a button click which will be there until another button with an image is clicked.
I have some code that was compiled without Unicode turned on in the Preprocessor Definitions. I need to access an API that had Unicode turned on in the Preprocessor Definitions (I believe that it is on by default for DLL's) .
I need to call a function in the DLL that requires a structure like:
struct READERINFO { TCHAR serial[32]; TCHAR altSerial[32]; TCHAR name[32]; TCHAR fccId[48]; TCHAR hwVersion[16]; int swVerMajor; int swVerMinor; char devBuild; };
It returns some information in the structure some of it is Unicode based however the program that is calling it is not Unicode. The preprocessors are not turned on because if they were there would be a lot of things to change in this code. The code is old code that I inherited and now I must interface to some new devices.
I declare my structure as :
READERINFO info; Then I call the function in the DLL which looks like: ApiGetReaderInfo(hAPI, &info, sizeof(into));
Which is defined as: ApiGetReaderInfo(HANDLE hApi, Struct READERINFO * ri, DWORD riSize);
Parameters:
hApiHandle to valid Api object instance riPointer to the READERINFO structure. riSizeSize of ri structure in bytes. Usually: sizeof(struct READERINFO).
When I call it from my program that does not have UNICODE defined in the Pre-Processors I get :
Characters like : ÌÌÌÌÌ in the TCHAR fields and invalid numbers in the integer fields. int ModuleVersion(HANDLE hApi) { struct READERINFO info; ApiGetReaderInfo(hApi, &info, sizeof(info));
[Code] ....
When I call it from my program that has some sample code just for this and has the UNICODE defined in the Preprocessors it works just fine. how I can call this from my old code and get the correct information. I have already tried to do the follow without success:
I'm fairly new to visual C++ programming in a windows form and the code displayed below works fine. However my issue is as soon as the program is running it will display "failure" on label7 as soon as the button is clicked. I understand why it is doing this as "a" is not in the textbox at this time so it reads the else line and displays the message. When I enter "a" in the textbox everything works fine and label7 changes to the right message.
I know how loops work. I know about bitmasks and how to display characters in binary. How should i proceed now in order to make an app that consists of online booking or knowing someones location.
What shall I learn in order to send values from 0.00 to 5.00? I'm working with they Hitachi 16x2 LCD display.I've been sending/displaying literal values on it all day.
Code:
SendCharater(unsigned char val)
where the variable val corresponds to the LCD character table.I can also send Hello World to the display, like so:
Code:
void putsXLCD(unsigned char *buffer){ while(*buffer) // Write data to LCD up to null { while( BusyXLCD() ); // Wait while LCD is busy SendCharacter(*buffer); // Write character to LCD buffer++; // Increment buffer } return; }
I could type in putsXLCD("5.00") in order to display it on the LCD, but how do I implement this automatically for values, e.g. 0.00 to 5.00?It appears I can only pass literal values through the function SendCharacter, meaning that in order to display "0" I have to pass the value 0x30 (the hex value of "0" on the LCD Table).
My current thought process:Much like passing "Hello World" in the function putsXLCD(), I need to assign a pointer that points at each value in the "array" that I need to send. E.g., I need to send 3.24, so I need to point to "3", fetch the corresponding hex value in the LCD table, in this case 0x34, and the pass this 0x34 into the SendCharacter function, and so on. So, if this is the case, how can I fetch the corresponding hex value?
I am using a windows application to start other processes. I am looking for a way to keep the form itself as the topmost program until it is closed, allowing the other programs enough load time.
I'm animating a human hand made in blender, so I allredy the hand, but I don't know how can I load this .obj to a windows form aplication that I'm working on. I need to load this .obj and animated .....
I have made a new Windows Phone App and I would like there to be two versions: one without ads (79p) and one with ads (free). I have sorted out everything expect one issue. I collapse the advert if the app is in the full version but the rest of the page stays the same. How do I move the 'content panel' after the advert is collapsed?
I have written a windows service which run continuously on a server. Interval time is 9 sec. On timer1_interval i am fecthing record from database and sending it to user. And changing its record status.
this service stop fetching records after running 4 to 5 days. We need to restart the service. there is no GUI involve in this code
In my class I'm trying to display the elapsed time as my label on a windows form. I've been reading up on all the different articles online and have tried these three methods all with the same result:
1. Using the System.Timers class 2. Built in Timer sub-class 3. Defining directly inside of my class the StartTime, etc. variables.
All of these still result in the following error: Cross-thread operation not valid: Control 'User_Interface' accessed from a thread other than the thread it was created on.
Currently, my windows form is being called by another class, but I'm not sure if this is the cause of the problem.
This is a sample of the code that I'm currently using to show the elapsed time:
