Question

[dllimort("user32.dll",EntryPoint+"",se......
.........AddForm(

Answer 1

一般不用吧???C#的打印功能可以满足吧?{
PrintDialog pd = new PrintDialog();
pd.PrinterSettings = new PrinterSettings();
pd.Document = new PrintDocument();
if( DialogResult.OK == pd.ShowDialog(this) )
{
// Look for the "TestGreg" form
string MyString = "TestGreg";
int nIndex = 0;
int count = 0;foreach(PaperSize pksize in
pd.Document.PrinterSettings.PaperSizes)
{
if ((String.Compare(MyString, pksize.PaperName)) == 0)
nIndex = count;
count++;
}pd.Document.DefaultPageSettings.PaperSize =
pd.Document.PrinterSettings.PaperSizes[nIndex];pd.Document.PrintPage += new PrintPageEventHandler(
OnPrintPage );
pd.Document.DocumentName = "Test";
pd.Document.Print();
}
}

Answer 2

using System.Runtime.Interc.......
[dllimort("user32.dll"]
public static extern bool AddForm(
    IntPtr      hPrinter,  // handle to printer object
    UInt32      Level,     // data-structure level
ref Form_Info_1 pForm      // form information buffer
);//具体的内容到c++中查一下就有了
public struct Form_Info_1
{
}

大家看看我的，为什么不行？？？using System;

[DllImport("winspool.drv")]
public  static extern int  AddForm(int  hPrinter,int  Level,byte  pForm);

Answer 5

To fupip(小贝)：
我的代码就是用那个apiviewer声明的，不过还是不能用。
public  static extern int  AddForm(int  hPrinter,int  Level,byte  pForm);中的byte  pForm是不对的，应该用指针或ref

Answer 6

我都说好几次了，api view 垃圾我才自己写个api explorer 你们为什么不用呢？用我的api explorer 肯定没这问题[DllImport("winspool.drv", EntryPoint="AddForm")]
public static extern int AddForm (
int hPrinter,
int Level,
ref byte pForm
