Re: reading bytes into directory

I think you'll need to create file objects in the directory, writing the bytes to those files. Files can be created using the File.Create static method.

You can only write on the server, not the client, and ASP.NET is not allowed access to the file system above the root of the web app. So, you have to write to locations underneath the root of your website.

Can you tell what menu item the mouse is pointing at? [modified]

Re: Can you tell what menu item the mouse is pointing at?

In C# how would you do this? Can you?
I am working in C++/CLI with Windows Forms. No one in the C++/CLI forum was aware of a way to tell where the mouse is pointing when the helpprovider event is called.

I want to have my compiled html help point to a topic specific to where the mouse is pointing (like as a menu item) but I can't seem to determine which control the mouse is hovering over.

My C++/CLI code is below.

private: System::Void FrmMain_HelpRequested(System::Object^  sender, System::Windows::Forms::HelpEventArgs^  hlpevent) 
{
  Point pt = this->PointToClient(hlpevent->MousePos);
  Control^ requestingControl = dynamic_cast(sender);
  Control ^ctrl = this->pt;GetChildAtPoint(pt);
  Control ^ctrl2 = this->pt;ActiveControl;
  Point ptMI = this->menuMainForm->PointToClient(hlpevent->MousePos);  
  Control ^ctrlMI = this->menuMainForm->GetChildAtPoint(ptMI);
  Point ptMenuHelp = this->miHelp->DropDown->PointToClient(hlpevent->MousePos);
  Control ^ctrlMenuHelp = this->miHelp->DropDown->GetChildAtPoint(ptMenuHelp);
  if( File::Exists(this->pt;helpProvider->HelpNamespace ) == true)
  {
    Help::ShowHelp(this, this->helpProvider->HelpNamespace);
  }
}

ctrl is the form itself and crtl2 is the last active mdichild in my application.
requestingControl returns the form (same as ctrl)and not the item the mouse is over.
ctrlMI and ctrlMenuHelp are undefined.

Hope someone can help Sigh | :sigh:

Hi Glenn

I tried out a few things and here's what I came up with.

If you've got a MenuStrip (e.g. File, Edit, View, etc.) and you're trying to see if the mouse is over a particular menu item (e.g. the File->Exit), you can do it like this:

Point localPoint = fileMenuItem.DropDown.PointToClient(hlpevent.MousePos);
if(exitMenuItem == fileMenuItem.DropDown.GetItemAt(localPoint)) // then we're over the exit menu item!

Does this help?

Wow. Thanks. I updated my code. I tried it but I got an undefined for the control.

I'm not sure I understand. You got null back for the control returned?

Wouldn't MouseEnter / MouseLeave or whatever work?

If you wanted an event for every menuitem. I was hoping there was a cleaner way.

Hi,

I have not used it myself, but the way I understand MSDN on Control.HelpRequested event
you should add an event to every Control for which you want to provide help; then in
the HelpRequested event handler the sender parameter points to the Control that currently
needs to show help.

For the menu dropdown items there is no event for the helpprovider. There is for the file menu itself but it does not tell you which menu item you are currently looking at.

OK, I see the problem now: MenuItem is not a Control. However MainMenu and ContextMenu
are, so you could enumerate their menu items recursively to find the one that is currently
selected (MenuItem.Selected property). Not sure what will happen when you move the
mouse up or down, selecting another menu item.

Thank You very much. It works like a champ! Here is my final code (c++/CLI).

for each ( ToolStripMenuItem ^tmpMS in this->menuMainForm->Items )
{
  for each ( ToolStripItem ^tmpCntl in tmpMS->DropDownItems )
  {
    if (tmpCntl)
    {
      if ( tmpCntl->Selected )
        String ^tmpCntlName = tmpCntl->Name;
      OpenHelpForMenuItem(tmpCntlName);
    }
  }
}

hi.. how do i browse a word document and get the data inside to my richtextBox ?

Re: browse word document

You'll either need to use the Word interop COM object (requires Word to be installed on the machine running your software), or use a 3rd party tool that parses Word documents to get the text data out or coverts it to RTF.

Use the ToShortDateString or ToLongDateString methods.

Standards are great! Everybody should have one!

I don't know what a Cla.selecteddate is, but if you're use a DateTimePicker you can set a CustomFormat.
