为什么加载栅格图层时出现“自动化错误”的问题？

<P ><FONT face="Times New Roman">。。。。。前面代码没问题</FONT></P>
<P ><FONT face="Times New Roman">Set pRasterDataset = pRasterWS.OpenRasterDataset("name")//这里是一个img格式影像文件，出现错误</FONT></P>
<P ><FONT face="Times New Roman">pRLayer.CreateFromDataset pRDataset </FONT></P>
<P >pMap.AddLayer pRLayer</P>
<P >另外我在arcmap环境下加栅格图层是总是有“Invalid raster dataset 。failed to create raster layer”，AO中的错误会不会跟这个有关呢？</P>

<P>还是路径中不要有中文，一有中文就会出现错误！</P>如果路径正确的话，这些栅格图形都是可以加载的！

<P>在AE中支持的影象格式好象不是很多,普通的删格文件比如.bmp的,jpg的,都不能正常加载到mapcontrol中!这是什么问题?</P>

<P>果然如此，路经全部改为英文就可以加了</P>

<H4>Description</H4>
<DIV>No raster files are listed when attempting to view them in ArcCatalog, add them to ArcMap using the Add Data dialog box, or by navigating to Tools > Options > Raster > File Formats.</DIV><br>
<H4>Cause</H4>
<DIV>Third-party, non-ESRI applications have incorrectly installed raster support files into the c:\windows\system32 directory.</DIV><br>
<H4>Workaround</H4>
<DIV>This solution will solve the problem of rasters not being visible. If an installed program references these files, it may not function properly after they are renamed. <br><br>
<DIV red? COLOR: 500px;><IMG src="http://support.esri.com/common/style/graphics/icons/warn.gif"> Do NOT delete the files unless you are certain they are no longer in use.</DIV><br><br>

<LI>Start Windows Explorer and navigate to C:\winnt\system32 or C:\windows\system32 directory and look for the following files: <br><br>Ethrlib.dll <br>Efileio.dll <br>ergxlib.dll <br>elib.dll <br><br>
<LI>If any of these files are present, rename them or move them to another location. For example, rename the file 'ethrlib.dll' to 'ethrlib.old'. <br><br>
