Managed C++/CLI

And if you have no expertise in this area, why are you being interviewed for such a role? Incidentally, your question has nothing to do with C++/CLI, it is should have gone to C / C++ / MFC Discussion Boards[^].

Yeah sorry, as Dave stated, not going to happen if you want someone to write your code for you, not how it works here on CP

The documentation at Win32Exception Class (System.ComponentModel) | Microsoft Learn[^] tells you which dll holds it.

FINALLY I MADE IT ;)

glthreads does not collide msride.

stat thread does not collapse prominent threads such as concept of algorithmics and totality.

depends on upper class methods, whether oos, or objs. Perls, or methods outside the class, are concurrent.

No. Partly because it's incomplete so we have no idea what it's supposed to do, partly because if you are trying to recreate an existing program, it's because the version you have can't be handed in without you presumably getting spotted for plagiarism. And if that's the case, you won't learn anything from the exercise if you do. Sit down with your assignment, think about it, and try designing an app from scratch. You end up learning more, and that means that your next assignment will be easier for you to complete yourself. If you are having problems getting started at all, then this may help: How to Write Code to Solve a Problem, A Beginner's Guide[^] And by the way: when I told you yesterday that we are an English language site, it's somewhat rude to ignore that and carry on posting in Indonesian. Being rude to people you want voluntary help from isn't a good way to start ...

This is an English language site, and we can only accept and answer questions in that language. I have run this through Google Translate to produce a probably-good version, but you should check it and make sure it does say what you are actually asking. And that code isn't recursive: it's iterative. Recursion happens when a function calls itself, either directly: int foo(int i) { if (i <= 1) return 1; return i + foo(i - 1); } Or indirectly: int foo(int i) { if (i <= 1) return 1; return i + bar(i); } int bar(int i) { return foo(i - 1); } Your code contains one method, which you do not call yourself! And please, do yourself a favour and indent your code more deeply - it's a lot easier to see what is going on with three or four spaces per indent rather than one. It's not a massive problem with a tiny code fragment like you show, but as your code gets bigger it becomes seriously difficult to work out what is going on!

This might help re: the data adapter. Quote: This overload of the Fill method does not implicitly call Close on the ADO object when the fill operation is complete. Therefore, always call Close when you are finished using ADO Recordset or Record objects. This makes sure that the underlying connection to a data source is released in a timely manner, and also prevents possible access violations because of unmanaged ADO objects being reclaimed by garbage collection when existing references still exist. "Before entering on an understanding, I have meditated for a long time, and have foreseen what might happen. It is not genius which reveals to me suddenly, secretly, what I have to say or to do in a circumstance unexpected by other people; it is reflection, it is meditation." - Napoleon I

Thank you very much Richard If MS docs had C++ version of this i would have not neded to bother you I was very confused as i dont do delegates if i can avoid it Very happy some C++/CLR people still exist ill mark as solved Here is the Final working MainForm() showing cross thread update of textBox, Random, and usage of other Member funtions This is here to help anyone that is as bad at this overcomplicated Parallel coding in C++/CLR (my opinion should be easier) "Parallel::For" - intellisense still moans about 2 or more overloads of it but who cares anyway, no one :¬) namespace CppTutorial { using namespace System; using namespace System::Threading::Tasks; using namespace System::Windows::Forms; /// /// Summary for MainForm /// public ref class MainForm : public System::Windows::Forms::Form { public: MainForm(void) { InitializeComponent(); // //TODO: Add the constructor code here // } protected: /// /// Clean up any resources being used. /// ~MainForm() { if (components) { delete components; } } private: System::Windows::Forms::TextBox ^textBox1; protected: private: /// /// Required designer variable. /// System::ComponentModel::Container ^components; #pragma region Windows Form Designer generated code /// /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// void InitializeComponent(void) { this->textBox1=(gcnew System::Windows::Forms::TextBox()); this->SuspendLayout(); // // textBox1 // this->textBox1->Dock=System::Windows::Forms::DockStyle::Fill; this->textBox1->Location=System::Drawing::Point(0,0); this->textBox1->Multiline=true; this->textBox1->Name=L"textBox1"; this->textBox1->Size=System::Drawing::Size(563,451); this->textBox1->TabIndex=0; // // MainForm // this->AutoScaleDimensions=System::Drawing::SizeF(6,13); this->AutoScaleMode=System::Windows::Forms::AutoScaleMode::Font; this->ClientSize=System::Drawing::Size(563,451); this->Controls->Add(this->textBox1); this->Name=L"MainForm"; this->Text=L"MainForm"; this->Shown+=gcnew System::EventHandler(this,&MainForm::MainForm_Shown); this->ResumeLayout(false); this->PerformLayout(); } #pragma endregion public: static MainForm ^staticmain; Random ^rand1

Thanks ByStorm. You saved my life. Been searching for this for weeks.

You have to include windows.h header. Here is an working example. #include #include #include int main() { DEVMODE devmode; devmode.dmPelsWidth = 1024; devmode.dmPelsHeight = 768; devmode.dmFields = DM\_PELSWIDTH | DM\_PELSHEIGHT; devmode.dmSize = sizeof(DEVMODE); long result = ChangeDisplaySettings(&devmode, 0); return 0; }

Try calling dataGridView1->Refresh() after you add the data.
