使用C# 实现直接操作dc 发传真 FaxStartPrintJob does't work

[bruce007]

我现在已经能使用
FaxServerClass fsc = new FaxServerClass();
try
{
fsc.Connect("");

FaxDoc doc = (FaxDoc) fsc.CreateDocument(@"c:\Off.bmp");
doc.FaxNumber = "8915";
doc.RecipientName = "tester";
int i = doc.Send();

}
catch
{
MessageBox.Show("fail to commit file!");
}
finally
{
fsc.Disconnect();
}
但是我想在发传真时， 得到fax 得 device context 直接朝 dc drawstring 或 drawImage
我知道基本得思路是要用到 FaxStartPrintJob SDK。 但下面的代码好象不行， 请高手帮看看。

IntPtr hServer = IntPtr.Zero;
FaxPrintInfo printInfo = new FaxPrintInfo();
printInfo.RecipientNumber = "8915";
printInfo.SizeOfStruct = System.Runtime.InteropServices.Marshal.SizeOf(printInfo);
printInfo.Reserved = null;
printInfo.OutputFileName = null;


FaxContextInfo contextInfo = new FaxContextInfo();
contextInfo.SizeOfStruct = System.Runtime.InteropServices.Marshal.SizeOf(contextInfo);
IntPtr jobId = IntPtr.Zero;

FaxDrill.FaxConnectFaxServer(null, ref hServer);
FaxDrill.FaxStartPrintJob(null, ref printInfo, jobId, ref contextInfo);

Graphics g = Graphics.FromHdc(contextInfo.hDC);
g.DrawImage(new Bitmap("c:\\Greenstone.bmp"), 0, 0);

FaxDrill.EndDoc(contextInfo.hDC);
FaxDrill.FaxClose(hServer);
[StructLayout( LayoutKind.Sequential)]
public class FaxPrintInfo
{
public Int32 SizeOfStruct; // structure size, in bytes
public String DocName; // pointer to document name to display
public String RecipientName; // pointer to recipient's name
public String RecipientNumber; // pointer to recipient's fax number

}

[StructLayout( LayoutKind.Sequential)]
public class FaxContextInfo
{
public Int32 SizeOfStruct; // structure size, in bytes
public IntPtr hDC; // handle to a device context
public String ServerName;
}



public class FaxDrill
{
public FaxDrill()
{
}

可能我写得比较乱， 我要实现得就是 将 FaxStartPrintJob 移植到 .net 托管代码中。 望高手指点。

这是一个asp 的例子，你可以参考一下

net_lover(孟子E章) 大哥：
我可能写得比较乱： 我得目的就是要在C＃中使用 FaxStartPrintJob。 只有这样才能 将自己要打印的内容 比较报表 图像， 放到一个fax 中发出去。

帮顶

[bruce007]

看来这个100分又泡汤了 ， 就没有一个人在winform下用编程方式发传真吗？ 晕！

[jkflyfox]

我发过，但是也只用用楼主的第一种方法。
帮顶吧，不要沉了。

[bruce007]

自己再顶一下。 看来csdn的高手也很有限的喔。 各位高手不用生气喔。

[michleliu]

我正好要学习这个，，帮顶。。。

[manonroad]

我正打算写一个组件在服务器端发送传真。关注中，顶一下。。。。

上面的代码可以发送传真，但在群发传真的时候，比如我在很短的时间内发送5封，只有4封能添加到传真控制台的发件箱。
