CStdioFile无法打开文本文件进行阅读 - 完全丢失！ [英] CStdioFile can't open a text file for reading - at a total loss!

问题描述

调试监视：

文件Q：\\Arduino \\ CNCLaserEngraver \\ExamplePCB.dfx确实存在。

The file Q:\\Arduino\\CNCLaserEngraver\\ExamplePCB.dfx DEFINTIELY exists.

但由于某种原因完全逃脱了我，CStdioFile构造函数无法打开，但发现该文件无法找到。

But for some reason that totally escapes me CStdioFile constructor fails to open with an exception stating that the file cannot be found.

问：是我的USB拇指驱动器.Visual studio在同一个拇指驱动器上打开了项目。

Q: is my USB thumb drive. Visual studio has the project open on this same thumb drive.

文件ExamplePCB.dfx未归类为"隐藏"或"系统"

The file ExamplePCB.dfx is not attributed as 'hidden' or 'system'

否则在我的代码中我打开一个.bmp具有相同名称和相同文件夹的文件（不同的文件扩展名 - .bmp）：

Else where in my code I am opening a .bmp file with the same name and same folder (different file extension - .bmp):

m_image.Load（m_strFolder +" \\" + m_strFilenameBMP）;

m_image.Load(m_strFolder + "\\" + m_strFilenameBMP);

这段代码完全正常 - .bmp文件按预期打开。

And this bit of code works perfectly fine - the .bmp file opens as expected.

那有什么区别？为什么不能CStdioFile o将我的.dfx文本文件放在同一位置?????

So what is the difference? Why can't CStdioFile opne my .dfx text file in the same location?????

void CGregsLaserEngraverDlg::ProcessDFX(LPCSTR lpszFileNameDFX, CStringArray &arrayFormatted)
{
	CStdioFile fileDFX(lpszFileNameDFX, CFile::modeRead | CFile::shareDenyNone);
	CString strLine;
	UINT32 nWidth = 0, nHeight = 0;

	if (fileDFX)
	{
		while (strLine != "$EXTMAX")
			fileDFX.ReadString(strLine);

		fileDFX.ReadString(strLine);
		fileDFX.ReadString(strLine);
		nWidth = atol(strLine);
		fileDFX.ReadString(strLine);
		fileDFX.ReadString(strLine);
		nHeight = atol(strLine);

		while (strLine != "ENTITIES")
			fileDFX.ReadString(strLine);
		fileDFX.ReadString(strLine);

		fileDFX.ReadString(strLine);
		if (strLine == "POLYLINE")
		{
			ProcessPolyline(fileDFX, arrayFormatted);
		}
	}
}

推荐答案

你尝试过其他工具吗？例如，从Watch窗口复制路径，然后将其粘贴到记事本的"打开文件"对话框中。

< span lang ="EN-GB"style ="margin：0px"> 也许它应该是".dxf"？
