Question

The user can change the columns width of the grid and my application must remember that and to restore it when the user open the project again. I am using the property Width:

                ph.GridColumn(0).Width

Answer

To get to the current runtime width you must use this call:

Gantt.GridColumnGet(index: Integer; var title, editkind, Width, SortEnable: OleVariant);

Send in variant variables and they will get the value for the Title, the editkind, the current runtime width and if the Sortenable was set or not..

Question

I am 3.0 license holder of phganttimepackage. I need to download the 3.2 which this site says is free for 3.0 license. can you guide me please

Answer

If you only need the latest ocx you can always find it here: https://plexityhide.com/pub/phGantXControl.zip

If you need the latest built install (help files and samples) you find it here: https://plexityhide.com/pub/phTimePack30COM.exe (but you probably have this already)

For VCL developers you can find the latest patch here https://plexityhide.com/pub/d7dcu.zip or here https://plexityhide.com/pub/d2005dcu.zip

Question

Can you help me, to disable any drag  or change time in the gant area. I want to give the editing outside the phgant. I don’t want the users to edit the time or the row of the Gantt.

Answer

In phGantTimePackage this can be handled with properties on the IphGantRow3.

IphGantRow3.TimeItems_CanChangeRow=false
IphGantRow3.TimeItems_CanMove=false
IphGantRow3.TimeItems_CanResize

In the GTP.NET 2.0 you have even better control; you set properties on the TimeItemLayout:

 AllowChangeRow  Limits the degrees of freedom available to user 
 AllowLinkReAssignStart  Controls if link re-assign can be done for the start of a link 
 AllowLinkReAssignTarget  Controls if link re-assign can be done for the target of a link 
 AllowLinkSelectionStart  Controls if link selection can be done for the start of a link 
 AllowLinkSelectionTarget  Controls if link selection can be done for the targer of a link 
 AllowMove  Limits the degrees of freedom available to user 
 AllowResizeEast  Limits the degrees of freedom available to user 
 AllowResizeWest  Limits the degrees of freedom available to user 

Question

I am using your Gant Time Package, and I would like to modify the properties of time items once they have been displayed. I could not find how to get one, even when giving them a UserIntegerReference.
Could you please tell me how to get a reference to these items.

Thank you.

Answer

The object model of the phGantTimePackage has tree nodes, gantt rows, layers and time items. To successfully navigate thru these items you will be helped by this complete iteration sample:

  // Iterate everything in the Gantt; Add an X to each tree node and move each time one day…

// Tree items

for(int i=0;i<axphGantX1.DataEntityList2LevTree.Count();i++)

for(int ii=0;ii<aList.Count();ii++)

as phGantXControl.IphDataEntity_Tree2;

for(int iii=0;iii<aTreeItem.GantRow.DataLists.Count();iii++)

for(int iiii=0;iiii<aDrawingLayer.Count();iiii++)

as phGantXControl.IphDataEntity_GantTime2;

// Another quicker way to get hold of all the time items

for(int i=0;i<axphGantX1.DataList3levGantTimes().Count();i++)

for(int ii=0;ii<aList2Lev.Count();ii++)

for(int iii=0;iii<aList.Count();iii++)

as phGantXControl.IphDataEntity_GantTime2;

Question

I am not sure if this is happening to anyone else I cant get any image (using ImageIndex)  to appear in all phGantX tree nodes in Windows XP and Windows 2003 Server. I ran sample VB ( Samples\ActiveX\VB6\GanttWithGrid ) to confirm this.

Please advise. Thanks.

Answer

This is probably not an issue of the phGantTimePackage but an imagelist problem.
The imagelist is part of the comctrl.ocx and this component has caused a lot of confusion on XP. The original comctrl32.dll that came with XP was not compatible with older versions and broke many applications. I think you should examine what version of the comctrl32.dll you are using and try to upgrade your XP machine to the latest version.

Microsoft issued a fix for the comctrl32.dll.

They describe the problem here (I hate pasting microsoft links into the KB, have you noticed how often they change their links just to break other peoples references, anyway here goes):

http://support.microsoft.com/default.aspx?kbid=811415

This is what they wrote so that you can use google to find the article if (when) the link above is broken…

SYMPTOMS

You can use SendMessage to get the image handle from various controls in Microsoft Windows Common Controls 6.0 (Mscomctl.ocx). By using SendMessage, you can pass TB_GETIMAGELIST, LVM_GETIMAGELIST, TVM_GETIMAGELIST, or TCM_GETIMAGELIST to get the imagelist handle for the Toolbar, ListView, TreeView, and TabStrip controls.

However, when you do this on a computer running Windows XP, the wrong handle is returned. If you call any other APIs, and then pass this handle, those API calls will not function correctly.

This problem occurs because Windows XP and Mscomctl.ocx load two different versions of Comctl32.dll that are not compatible.

A supported fix is now available from Microsoft, but it is only intended to correct the problem described in this article. Only apply it to systems that are experiencing this specific problem. This fix may receive additional testing to further ensure product quality. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next Visual Studio 6.0 service pack that contains this fix.
