关于调用系统画图板

[caiyan807]

我想在代码中调用windows系统中的画图板工具打开一幅图像，应该怎么做？

[ivan_08]

定义一个按钮，关联一个函数，如OnColor（）
{
CColorDialog dlg; //定义颜色对话框类的对象
if(dlg.DoModal == IDOK) //调用颜色对话框
m_color = dlg.GetColor(); //返回选中的颜色
}

ShellExecute(NULL, _T("open"), _T("mspaint.exe"), _T("c:\\1.bmp"), NULL, SW_SHOWNORMAL);

汗，我看错了，正好学习下二楼的

谢谢楼上，不过就差一点，我要打开的是jpg，但是它提示说找不到bmp,不知道是那个参数不对啊？

你是不是把文件名写错了？ShellExecute的第4参数。

MsPaint 不会直接打开jpg文件...可以放到mspaint.exe的命令行参数中

I have problem with ShellExecute() for open image with Ms Paint :
I tried :
ShellExecute(NULL,"Open","mspaint.exe",szFileName,NULL,SW_SHOWNORMAL);

If szFileName with space ("C:\\Documents and Settings\\pic.jpg"
etc...) -> MS Paint cannot open this file !


Is there some error message from Paint?

I'd guess there's quotes missing from the %1 parameter in the file
type association in the registry settings.


The OP isn't using file type associations. He or she is invoking
mspaint.exe explicitly, passing the file name as command line parameter.

Run中 -> mspaint "C:\pic12.jpg"
