This article mainly introduces "how to use C # Pocket PC 2003 equipment". In daily operation, I believe many people have doubts about how to use C # Pocket PC 2003 equipment. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts about "how to use C # Pocket PC 2003 equipment". Next, please follow the editor to study!

Suppose we need to click a button in the main form FMMain to open the sub-form FMChild and pass a value to the sub-form FMChild. In general, the code that we click the button to display the sub-form FMChild is:

FMChild fmChild = new FMChild (); fmChild.ShowDialog (); fmChild.Dispose ()

If we need to pass the value of string strValueA in the main form FMMain to FMChild, then we first do the following for strValueA:

Private string strValueA; public string StrValueA {get {return strValueA;} set {strValueA = value;}}

Make it a property of the main form FMMain, and then modify the code that displays the sub-form to one of the following.

Method 1:

FMChild fmChild = new FMChild (); fmChild.ShowDialog (this); fmChild.Dispose ()

Method 2:

FMChild fmChild = new FMChild (); FMChild.Owner = this;fmChild.ShowDialog (); fmChild.Dispose ()

Then declare a main form FMMain object in the modified sub-form FMChild

FMMain fmMain

Add the following code where you need to use the string strValueA of the main form FMMain:

FmMain = (FMMain) this.Owner

In this way, you can get the value of strValueA in the main form FMMain.

At this point, if you need to pass the string strValueB in the sub-form FMChild to the main form FMMain, do the same with string strValueB.

Private string strValueB; public string StrValueB {get {return strValueB;} set {strValueB = value;}}

So after you close the sub-form code fmChild.Dispose ();, you can write some code to save or process the strValueB of FMChild, for example:

String strTmp = fmChild.StrValueB

Note that displaying the sub-form FMChild in the Visual C# smart device Pocket PC 2003 device application can only be used:

FMChild fmChild = new FMChild (); FMChild.Owner = this; fmChild.ShowDialog (); fmChild.Dispose ()

ShowDialog () is not overloaded in the Visual C# smart device Pocket PC 2003 device application.

At this point, the study on "how to use C # Pocket PC 2003 equipment" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
