Deploying Applications Using The Chart Control
The Microsoft chart control is included in .NET 4 and above. For .NET3.5 your application distribution package needs to include mschart.exe and install it as a prerequisite if it is not already on the users PC. You can’t simply include a .dll – mschart.exe needs to be run. Adding MS Chart Controls as a prerequisite […]
Rounding
Using this int i; float f = 1.53; i = Convert::ToInt32(f); Will cause i = 2, because Convert::ToInt rounds to the nearest value. To force rounding down use: i = Convert::ToInt32((int)f);
Creating Random
Create random number System::Random ^rand = gcnew System::Random(); //Creates seed value from system clock if no seed supplied iTemp = rand->Next(1, (100+1)); //Min possible value, max possible value+1 Fill an array Random ^rand = gcnew Random(); rand->NextBytes(DecodedHexFile); //Fill entire array with random values
Creating a Pause / Delay
Threading::Thread::Sleep(250); //Pause time in mS
