I found a very helpful code solves this problem. Maybe you can use this code to fix the problem with Vista and w7. http://www.dotfusion.net/vista-compatible-open-and-save-dialog-in-lazarus-freepascal |

looks like aready reported in 2006. see report 0007797. |
|
|
I'm not able to reproduce on windows 7 + unchecked "Hide extensions for known file types". Please retest and close if it is fixed for you or reopen with more instructions. |

I can't test on W7 now, only on Vista and problem still exists. I simple put this code on button click: - SaveDialog1.Filter:='text (*.txt)|*.txt|csv (*.csv)|*csv'; - SaveDialog1.FileName:='Project'; - SaveDialog1.Execute; and explorer is set to display extensions. I attached screenshots - withTXT.jpg - what I see when SaveDialog show - withCSV.jpg - what I see when I change filter to csv, FileName is still with txt (user need manually change extension) |

tested with rev 24900 (with or without dOldAutoSize). Box with files works ok, when change to csv, files are filtered to show only csv files. Only filename doesn't want to change. |
|
|
Why Filename should change? Filter is only used to filter the shown files. It has no effect on filename. So can we close this issue? |
|
|
@Paul: the filter actually affected the filename already by adding ".txt" suffix. Logically it should change the suffix when filter changes. I haven't tested it myself but I would say this is inherent behavior of Windows SaveDialog. The bug report should go to Microsoft. |

No Filename but only extension. I realized that it just not necessary to change the file name extension (what if we would have couple extensions in one filter line). I suggested this as it work in MSPaint and others but it's probably not a standard feature (but it would be nice if I could change extension on filename). In Windows XP extension is not displayed in the file name (regardless of whether we have set display extensions in explorer) so there is no problem. OK we can close this. |
|
|
BTW If I use SaveDialog code from link in my first post I don't have extension in filename. |
|

I see no good way of hiding file extension. Moreover this is standard behavior of windows dialog. In your example it does not change file extension when you choose csv because this file type is not registered. I tried with .pas files and it changes the extension in this case. Please close if ok. |
