Hi Guys,

I am trying to write some methods to locate a folder in a treeview. Basically I want to pass the following string to my function and then it should one by one open the folders until it reaches the final folder:

Code: click into code to enlarge

LocateFolderInLeftHandPane(@"My Computer\C:\Program Files\Common Files\Adobe\Color\Profiles\Recommended")

Now this code is similar for what you would normally run on the windows explorer.

My methods are:

Code: click into code to enlarge

public void LocateFolderInLeftHandPane(string path)
{
// Break down the path
string[] folderList = path.Split(@"\".ToCharArray());

// Get the left hand side pane
Control control = mSelf.FindControlId(ControlNames.FileSelectorDialog.AV_FILE_SELECTOR_T REEVIEW_CONTROLID);

// Get the treeview
TreeView tw = new TreeView(control.Handle);

// Get the element for the treeview
Element treeElement = tw.Element.FindChild(Role.Outline);

// Locate
Locate(tw, treeElement, folderList, 0);
}

and

Code: click into code to enlarge

private void Locate(TreeView treeView, Element folder, string[] folderList, int index)
{
// If we have reached the last folder in the fields array then exit
if (index > folderList.Length - 1)
{
return;
}

// Get the count for the children
int childCount = folder.GetChildCount;

// Traverse the tree
Element node = null;
for (int i = 0; i < childCount; i++)
{
// Get the node
node = folder.GetChild(i);

// If the specified folder is found then expand it
if(node.Name.IndexOf(folderList[index]) > -1)
{
// Expand
TreeNodeExpand(node);

// Increment to get the name of the next folder
index++;

// Find the current folder
node = treeView.Element.FindChild(Role.Outline);

// Break out of the loop
break;
}
}

// Recurse
Locate(treeView, node, folderList, index);
}

and

Code: click into code to enlarge

protected void TreeNodeExpand(Element folder)
{
// Check to see if the node is collapsed then expand it
if ((folder.State & State.Collapsed) != 0)
{
// Double click the folder
ElementDoubleClick(folder);

// Wait for it to get expanded
while ((folder.State & State.Collapsed) != 0)
{
// Wait
Wait(Constants.TIMEOUT_TINY);
}
}
}

Now the problem is that if you also have the following folder in your file system:

Quote:

C:\Program Files\Adobe

and you want to find the folder:

Quote:

@"My Computer\C:\Program Files\Common Files\Adobe\Color\Profiles\Recommended"

then the code will open the folders upto:

Quote:

C:\Program Files\Common Files

Then it will try to open the following following folder:

Quote:

C:\Program Files\Adobe

Now ifyou try to use the following line of code, then the node's child count is set to zero:

Code: click into code to enlarge

node = treeView.Element.FindChild(Role.OutlineItem, node.Name, node.Class, node.Location);

and if you try to use the following then the node gets set to null:

Code: click into code to enlarge

node = treeView.Element.FindChild(Role.Outline, node.Name, node.Class, node.Location);

Does anyone know how to fix this?

Does anyone have the code to locate a folder in the treeview?

Appreciate your help.

Thank you.

Behdad.

I found out how to locate the folder. All I had to do was:

Code: click into code to enlarge

public void Locate(string[] folderList)
{
Control control = myForm.FindControlId(TREEVIEWCONTROLID);
TreeView tw = new TreeView(control.Handle);
Element child = tw.Element.FindChild(Role.Outline);
child = child.GetChild(0);
child.Select(Selection.TakeFocus | Selection.TakeSelection);
for (int i = 0; i < folderList.Length; i++)
{
System.Threading.Thread.Sleep(500);
int selectedChild = tw.SelectedItem;
tw.SelectItem(folderList[i], selectedChild);
tw.SendKeys("{RIGHT}");
}
}

We found and corrected a bug in a tree view function of RanorexCore.
You can navigate the tree view path in the next release V1.1.0 as follows:

Code: click into code to enlarge

LocatePath(@"My Computer\System (D:)\Ranorex\Bin\Net2.0");

static void LocatePath(string path)
{
// Break down the path
string[] folderList = path.Split(@"\".ToCharArray());

Form form = Application.FindFormClassName("ExploreWClass", 1);

// Get the left hand side pane
Control control = form.FindControlId(100);
TreeView treeView = new TreeView(control.Handle);

// Locate the path
bool ret = Locate(treeView, folderList);
}

static bool Locate(TreeView treeView, string[] folderList)
{
// Get the root tree view element in the control
// The tree view itself has the role Role.Outline
Element treeElement = treeView.Element.FindChild(Role.Outline);

// Get the count of the children
int childCount = treeElement.GetChildCount;
// Traverse the tree
int level = 0;
for (int i = 0; i < childCount && level < folderList.Length; i++)
{
Element node = treeElement.GetChild(i);
if (node == null)
break;

if (node.Name == folderList[level])
{
node.Select(Selection.TakeFocus | Selection.TakeSelection);
Mouse.MoveToElement(node);
treeView.SendKeys("{RIGHT}");
if (level == folderList.Length - 1)
return true;
else
level++;
}
}
return false;
}
