I'm using a perfectly usual SaveAs dialog (in Delphi Win32 XE2, the system is Win 7 /64), setting OFN_OVERWRITEPROMPT (or the Delphi wrapper's equivalent dlgSave.Options := [ofPathMustExist, ofOverwritePrompt];. So if I select an existing file, the dialog asks for confirmation to overwrite the file.
Everything works as it should except for one silly thing: when I choose a file, then delete that file right in the same dialog, then press OK, the dialog still asks if it's ok to overwrite the (already deleted) file. Apparently, the dialog checks file existence against a pre-loaded list, not the file system. The problem is not specific to Delphi and can be shown very easily even in Notepad:
Run Notepad.exe
Enter some text
Save as a file
Click File Save As again, in the SaveAs dialog do:
Click on the same file to select it,
Right-click and delete the file,
click OK.
The file is no longer there, but you still get the overwrite prompt.
Can anybody please suggest a way to work around this minor but annoying Windows bug? I assume some message processing / callbacks / hooks might be required? A way of checking the file presence in code while the modal SaveAs dialog is open?

Before I did a clean install of my desktop with windows 10 I had .srt to open by default in Sublime Text after I have formatted my computer I somehow miss the file format .srt under 'Choose default apps by file type'.
The .srt should be be between the .srf and .srw file types, but it isn't (as shown in the image here: https://answers.microsoft.com/en-us/windows/forum/windows_10-desktop-winpc/srt-files-back-to-unknown-application/e33cace8-dd59-4557-9631-e8e82a8307b3?auth=1).
If I try "open with and find Sublime (or any other software for that matter, it will open it, but it will not set it as the default program even though I checked the box) and will still appear as an unknown filetype....
If I go into properties and try to change the "open with" from there, it will just keep showing "choose a program" even still.
tried updating the computer and restart it and frankly I've given up, and it doesn't seem anyone have run into this problem before of missing a filetype under 'Choose default apps by file type'.
I also tried
1) Settings - Indexing Options
2) Advanced button
3) File Types tab
4) Add New Extension to List box, type in extension (without a period) such as "py"
5) Click Add, OK and Close
and while the format does appear in the 'Choose default apps by file type', it still doesn't let me change it at all...
Anyone got an answer to this problem?
I have now tried to go into regedit and use "search" on anything that included "sublime" and ".srt" and deleted them all... restarted the computer, reinstall sublime. The file extension I created myself in the indexing option, has been deleted.
Sublime can still open the file, but if you try to make it default program by simply opening it or or going into the files properties and do it that way, it will just open the file without it making it the default program as it should.
going into the indexing option and create the .srt extension format so it can be found under 'Choose default apps by file type' will allow you to choose notepad or wordpad as default program. When I choose either of them, the will just freeze for 1-2 sec and then nothing has changed and the extension havn't been associated with any of the programs.
I tried following the following links, and nothing has worked. Guess I'll just have to accept there is no solution rather than to live with out until I reform my PC again, cause it works without a problem on my laptop and I formatted them both the same time and installed the exact same things on both and the exact same way s:
I've tried to use the following links for help, but to no avail since non of the things I have tried have fixed it.

Windows 7 file extension association
One way to get an empty .srt entry back in the 'Choose default apps by file type' control panel is to create a new key for .srt in your registry under HKEY_CLASSES_ROOT:
Open Registry Editor, e.g. by typing 'regedit' into the start menu or a command prompt
At the top of the tree, right-click on 'HKEY_CLASSES_ROOT', New -> Key
Rename the new key to '.srt' and press enter to save
Is there some way I can programmatically (in VBS) OR by using CMD/RUN open the 'Open' dialog that contains the places bar and a browser but without opening say notepad or MSpaint?
http://i.technet.microsoft.com/dynimg/IC354177.jpg
I'd like to use this on the desktop itself, it would be really cool if there was a DLL I can just use instead of having a VBS file but if not i'm sure its possible in VBS.
I'm busy searching where the actual open dialog box comes from, it should come from some DLL file somewhere.
I might even consider stopping the windows shell from opening all together and just using this open window as the shell on some computers.

What version of Windows are you on?
"UserAccounts.CommonDialog" was the way to do this in XP. But it no longer exists in Windows 7. You may be able to use some of the flags available for the BrowseForFolder() method to make it look like a file open dialog. See this page for an example.
XP Edit:
Here's an XP example using UserAccounts.CommonDialog.
With CreateObject("UserAccounts.CommonDialog")
.InitialDir = CreateObject("WScript.Shell").SpecialFolders("Desktop")
.Filter = "All Files|*.*"
' Show the dialog. If [Open] is clicked, save the name of the selected file...
If .ShowOpen Then strFile = .FileName
End With
I would like to write a windows program that would enable the user to choose a ppt file. When that ppt file starts the slideshow, my program would automatically display some message in front of the slideshow. When the slideshow is over, my program would close itself. What do I need to learn to write this program?
I'm not good with VBS (which I'm sure you could use for this) but if you set your show's extensions to .PPS instead of .PPT that will force them to start playing automatically on open. Then you won't need to see when the show starts because you'll control that.
As for opening it, if you write BATCH script you can use it to prompt for a file location but it will all be manually typed because it will load from the command window. If a show opens, the command screen can stay open until that slideshow closes, then continue with the next line of script.
Depending on if these are your powerpoints that you want opened, I personally would put VBA script in them to trigger On_Open and On_Close That will get you a clean customizable popup error message.
Edit
After doing some quick searching the On_Open and On_Close is not found in PPT, you would need to install an add-in.
A lot of dev environments have some basic parsing logic applied to the output of programs while debugging such that if a program writes to the console (as a result of an error, assert) something like:
/Users/Foo/Project/SomeFile.m:12 - SOMETHING BAD HAPPENED HERE
the file path & line name are automatically detected as link to source, and one can click or double click on the text in question inside the console window to make the source editor jump here.
I have been trying to find out if XCode has something similar, but I haven't had much luck. Is any such functionality missing in XCode or am I just not finding the preferred text shape that it prefers?
Thanks
I just remembered "Open Quickly…". If you copy the text of the file name, then use the "Open Quickly…" function (Cmd-Shift-O by default), you can paste the filename in and press enter, and it will display the file.
I want to replace the standard system open file dialog with the one I wrote, that means no matter within which programs you are opening a file, my dialog will be shown instead of the standard one, is this possible?
It seems that that there is no such API provided to accomplish this, is it possible to use some hooking technique, but this has to be reliable and not to be treated as spyware by anti-virus tools?
any other options?
If this is not possible, is it possible to add to the spacebar or toolbar in the standard open file dialog a button which invokes my dialog, which allow users select a file and in turn returns the path of the selected file to the "File name" input box of the standard dialog?
Any hits, links and code examples will be appreciated.
Starting in Vista, the FileOpen/FileSave dialogs are now "Common Item Dialogs" of which IFileOpenDialog & IFileSaveDialog are the two published implementations.
Since they're just COM objects with known CLSIDs you might get away with just replacing them by re-registering using their CLSIDs. Never tried something like that, might trip all sorts of alarm bells.
Pre-Vista file dialogs can be hooked in process, but I've never come across anything about global hooks or equivalent.
If you copy a file/folder to a dialog's filename field it usually pastes the full path anyway.
For example, if you have open both a program calling the standard open/save dialog box and also have a window open at the file or path that you want to work with (open from/save to), you can simply copy the file/folder from the explorer window, and then paste into the filename field of the dialog box, and it will insert the full path of the file/folder. No custom script is required!
Alternatively, for those programs that use custom dialog boxes where this step fails, copy the same file/folder in the window into the address bar of the same window (assuming it is visible). This will paste the full path, which you can copy again, and then paste this full path into the custom dialog box. I often use this when creating Office hyperlinks (Ctrl+K), because the Insert Hyperlink dialog does not work for the first method.
You can also use similar methods but paste into address bar fields and it works.
