    <p>how may I check if a file is already opened in some Excel instance?</p> <p>I use DXL (DOORS) language but it should be independent from this language.</p> <p>Is there any OLE method that I can call to check which file is opened and compare that with the path/filename?</p> <p>and if that is possible, can I close only that worksheet/file in that Excel application?</p> <p>edit: this is what I got till now, this works but only once. DXL leaves an Excel.exe process open and in next checks that instance is used which has no open workbooks or even no window at all.</p> <pre><code> if (confirm "File \"" fPath "\" already exists. Do you want to overwrite it?") { // check if file is opened in any Excel instance OleAutoObj oleWorkbooks = null; OleAutoObj oleExcel = null; OleAutoObj oleWorkbook = null; OleAutoArgs autoArgs = create; oleExcel = oleGetAutoObject("Excel.Application"); bool opened = false; // if excel is opened if(oleExcel != null){ d("Excel is opened"); // Get workbooks and open file oleGet(oleExcel,"Workbooks", oleWorkbooks); // compare each open workbook int count = 0; oleGet(oleWorkbooks,"Count", count); string workbookname = ""; string sPath = replace(fPath, "\\", "/"); sPath = stripPath(sPath, true); while (count &gt; 0) { d("checking opened document"); clear(autoArgs); put(autoArgs, count); oleGet(oleWorkbooks,"Item", autoArgs, oleWorkbook); oleGet(oleWorkbook, "Name", workbookname); opened = sPath == workbookname; if(opened) { if(confirm "The file is currently opened in Excel. It must be closed. Do you want to close the document?") { clear(autoArgs); oleMethod(oleWorkbook,"Close",autoArgs); } break; } count--; } } oleCloseAutoObject(oleExcel); oleCloseAutoObject(oleWorkbooks); oleCloseAutoObject(oleWorkbook); // todo leaves excel process open if(!opened) { streamOutputData = write fPath; streamOutputData &lt;&lt; sOutput; close streamOutputData; return true; } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
