Click on that button and the form will appear.
If it's a lot of buttons, is that what we usually write?
| The code is as follows |
Copy Code |
| private void Button3_Click (object sender, EventArgs e)
{
Get the button name that you clicked
String btnname = ((Button) sender). Name;
if (Btnname = = "Button1")
{
Working with Forms
}
else if (btnname = "Button2")
{
Working with Forms
}
Else
{
Working with Forms
}
} |
This can only be done in a single, if more than 100 thousand will not, the code is too cumbersome.
| The code is as follows |
Copy Code |
| <summary>
Open a new Subform
</summary>
<param name= "StrName" > Form's class name </param>
<param name= "AssemblyName" > The name of the class library where the form is located </param>
public static void CreateForm (String strName, String assemblyname)
{
String path = assembly option name for assemblyname;//project
String name = StrName; The name of the class
form doc = (form) assembly.load (path). CreateInstance (name);
Doc. Show ();
}
private void Button1_Click (object sender, EventArgs e)
{
Get the button name that you clicked
String btnname = ((Button) sender). Text;
CreateForm ("WindowsFormsApplication1." + Btnname, "WindowsFormsApplication1");
} |
The mode of the subform you are using can also be restricted by using the following code to limit the repeated open
| The code is as follows |
Copy Code |
| <summary>
Open a new Subform
</summary>
<param name= "StrName" > Form's class name </param>
<param name= "AssemblyName" > The name of the class library where the form is located </param>
<param name= "Mdiparentform" > Parent form </param>
public static void CreateForm (String strName, String assemblyname, Form Mdiparentform)
{
int Index = Strname.lastindexof (".");
String FormName = strname.substring (23);
if (! Showchildform (FormName, Mdiparentform))
{
String path = assembly option name for assemblyname;//project
String name = StrName; The name of the class
form doc = (form) assembly.load (path). CreateInstance (name);
Doc. WindowState = formwindowstate.maximized;
Doc. MdiParent = Mdiparentform;
Doc. Show ();
}
}
<summary>
Prevent subforms from opening again
</summary>
<param name= "P_childrenformtext" ></param>
<param name= "Mdiparentform" ></param>
<returns></returns>
public static bool Showchildform (string p_childrenformtext, Form mdiparentform)
{
int i;
To detect the subform of the current form in turn
for (i = 0; i < MdiParentForm.MdiChildren.Length; i++)
{
Determines whether the Text property value of the current subform is the same as the string value passed in
if (MdiParentForm.MdiChildren.Name = = P_childrenformtext)
{
If the value is the same, this subform represents the subform you want to invoke, activates the subform, and returns a value of True
MdiParentForm.MdiChildren.Activate ();
return true;
}
}
If there is no same value, it indicates that the subform being invoked is not open, and returns a value of False
return false;
} |
All right, these are the personal test, we can enter the reference.
