Arrays In A Class
Resizing An Array Of Objects In A Class It won’t work. Best approach usually is to use a list instead of an array. Alternatively you have to copy the array to a new array with a different size using Array::Copy Array::Copy(obj->ClassValueArray1, ClassValueArray1, NewSize);
.Using List
Unlike arrays, the List collection type resizes dynamically. If you are working with data where you would need to be resizing an array a lot then use a list instead. It is ideal for linear collections that you don't need to adjust using an index. Good resources http://www.dotnetperls.com/list You need this namespace using namespace System::Collections::Generic; […]
Copy A Class
Copying A Class If your class has no pointer and no dynamic memory allocation then you don’t need to provide a copy function – you can use ‘=’. However if this isn’t true (i.e. your class contains a string or other object), then you need to provide a copy function or otherwise if you try […]
Copy to clipboard
System::Windows::Forms::Clipboard Copy text to the clipboard Clipboard::SetText(SomeTextBox->Text); Copy Image To Clipboard MemoryStream ^MemoryStream1 = gcnew MemoryStream(); Chart1->SaveImage(MemoryStream1, DataVisualization::Charting::ChartImageFormat::Bmp); System::Drawing::Bitmap ^Bitmap1 = gcnew System::Drawing::Bitmap(MemoryStream1); System::Windows::Forms::Clipboard::SetImage(Bitmap1);
Working With Characters In Strings
Replace A Character In A String sTemp = “ABCDEF”; sTemp = sTemp->Substring(1, 1); //Get a single character from the source string Result = Result->Remove(LICENSER_PRODUCT_ID_1_INDEX, 1); //Remove the character to be replaced in the destination string Result = Result->Insert(LICENSER_PRODUCT_ID_1_INDEX, sTemp); //Add the character
Making Asynchronous Tasks Thread Safe
See this solution to making writing a file thread safe
Write File Thread Safe
This example is based on writing a file from asynchronously received TCP packets. FileStream->Write is not thread safe, so this approach deals with letting file write occur in the background and waiting for it to complete before writing the next received block of data bytes. In your header file FileStream ^ClientRxFileStream1; IAsyncResult ^ClientRxFileStreamAsyncResult1; array<Byte> ^ClientReceiveFileWriteBytes; […]
Link two forms
Set the secondary form owner to the main form. For instance, if you have created another form you do this: frmMyOtherForm->Owner = this;
Serialization Of A Class
Serialization is the process of storing the state of an object or member for storage or transfer and deserialization is the process of restoring it. Serialization is dead easy in .Net, as long as the same assembly is performing both the serialisation and deserialisation. Formats Serialize as Binary – More compact and faster, works well […]
