Hi,
Iam using Vs2015, While I try to Open a file using OpenFileDialog, Iam receiving the error
"Unhandled exception of type" System.AccessViolationException" occoured in system.windows.forms.dll
Additional information: Attempted to read or write protected memory.This is often an indication other memory is currupt.
My Codes
[code]
openFileDialog1->Title= "Select Your Excel File";
openFileDialog1->InitialDirectory = "C:\";
openFileDialog1->Filter = "Excel Files (.xls)|.xls|All files (.)|.";
openFileDialog1->FilterIndex = 2;
openFileDialog1->RestoreDirectory = true;
if (openFileDialog1->ShowDialog() == System::Windows::Forms::DialogResult::OK) {
MyExcelFile = openFileDialog1->FileName;
}[/code]

openFileDialog1->Filter = "Excel Files|*.xls;*.xlsx;*.xlsm";Please try the above code to see if you still exits the problem.

2021-10-06T03:09:48.75+00:00 @Paranthaman , your project is C++/CLI project instead of C++ project. Please refer to the link create-c-windows-forms-application-in-visual-studio-2017 check if your setting is correct or not. If the problem still exists, I recommend that you use vs2017 or vs2019 to have a try to test the code.
