Apparently, these calls are *not* valid calls.

TObject:Equals is not a method in TObject For C++ Builder 2007.
RequestAlign is *not* a public method for TWinControl.

Any ideas? Have I installed the wrong version of SCP?

I uninstalled and reinstalled the packages and I now get past these errors.

However, when I like I now get a raft of "unresolved externals", all originating from the plasmatech obj files. These are standard VCL functions such as "TRegistry::ReadInteger", and "TObject::Equals"

What am I missing?

Thanks,
Ian

I just bought and installed SCP VCL 2 into my Rad Studio 2007 app.

When I attempt to compile it, however, I get the following error:
[BCC32 Error] uptshell95.hpp(39):E2304 Constant variable 'ShortInt' must be initialized
[BCC32 Error] uptshell95.hpp(39):E2141 Declarations syntax error

I get a ton of these, making my app uncompilable.

Is there some flag I need to set to get this to compile properly? The install seems to have worked okay.

Thanks.

Edit: I should point out that this is a C++ App, and I am using only the C++ Personality, although I get the same errors if I use the Delphi personality too.

uptshell95 is a Codegear generated HPP file. If I change ShortInt to "short int", it works, but them I start getting other errors. Should I have install the Delphi 10 version? (There was no option for a C++ Builder 2007 version on install).

Can you add DoubleBuffered properties to the scp components so glassframes can be used in Delphi 2009?

Also, usually I like to set the SelectedPathName before the Form is shown but SelectedPathName is not a public property so using other components to save and restore the SelectedPathName to the registry or ini file is not easy to do becuse these other components require a public property.

Can a public property be added to the components to hold the SelectedPathName?

Thanks
Bill

SCP VCL 2 :: Drag a desktop shortcut to a PTShellList

I'm using Vista Ultimate 64 and Delphi Win32 2007.

When you right click on a desktop shortcut and drag it onto the file pane of Windows Explorer a menu pops up with the following options:
Copy Here
Move Here (in bold)
Create Shortcust Here
Cancel

When I right click and drag a desktop shortcut and drop it on a TPTShellList I only get these options:
Move Here (in bold)
Cancel

Why don't I get the same menu options when right-click dropping shortcuts on a PTShellList?

It gets stranger:

- on my own XP Pro SP3 and Windows 2000 SP4 systems I see the little rectangles (possibly Unicode character 25A1) in the Title and Status strings.

- on my wife's XP Pro SP3, and my own Vista Ultimate systems I don't see the little rectangle!

Does this ring any bells with anyone? I'll ask on the CodeGear groups as well.

Thanks,
David

It doesn't here, Tim. I'm using the latest patched version of Delphi 2007.

There is still a problem in that UTF7 encoded strings that are 0-length (i.e. UTF7 prefix and nothing following) are not detected as UTF7. So if you leave the status text empty you will see the UTF7 prefix rather than a blank string.

To fix this, in the UPTUnicode.pas locate the two overloaded implementations of the PTIsUTF7 function.

Change the condition
Length(AString) > 5

to
Length(AString) >= 5

This is not an issue on Delphi and C++Builder 2009. The UPTUnicode unit doesn't really do anything on those platforms.

This fix will be included in the next release.

SCP VCL 2 :: RE: TPTShellTree: invisible node ImageIndex

Author: Tim Knipe
Posted: Mon Oct 27, 2008 9:51 pm (GMT 11)
Topic Replies: 1

For performance reasons, the ImageIndex of a TPTShellTree node is not evaluated until it is displayed.

You can obtain the image index directly from Windows using the UPTShellUtils.ShellGetIconIndex function.

Use TPTShellTree.GetDataFromNode to retrieve a TPTShTreeData object for a corresponding TTreeNode. Then grab the TPTShTreeData.AbsoluteIdList property and call UPTShellUtils.ShellGetIconIndex to get the image index. This will cause Windows to load the icon if it's not already loaded, so the first time through might take some time.

Certain "verbs" don't work within applications built with Delphi or C++Builder 2009 and the Shell Control Pack 2.2.77. This causes operations like copy/paste and delete to fail.

To fix this problem, open UPTShellControls.pas and search for GCS_VERB and replace with GCS_VERBA.

This issue will be addressed in the next release.

SCP VCL 2 :: TPTShellTree: invisible node ImageIndex

Author: praxalia
Subject: TPTShellTree: invisible node ImageIndex
Posted: Fri Oct 17, 2008 9:22 pm (GMT 11)

Hi all!

I have just registered the Shell Control Pack VCL2 and I have a question on TPTShellTree.

I am programming a backup program which reads the tree structure of different PCs and streams it back to an administrator program. I use the TPTShellTree to get the File information on the PCS (folders, icons, etc) which works OK, but I see that the imagindex property of each node has a value of 0 if the corresponding node is not VISIBLE. When I get the information in the administrator, all the nodes which were clipped out of the client control canvas appear with the wrong icon, and if I make the whole TPTShellTree invisible (as it must be in the final program, now I am working on a prototype) all of the nodes.imageindex reads as 0, except for the root node.

How can I force the nodes of a TPTShellTree to show the real imageindex value even if the tree is not visible?

Thanks in advance for your help
