Issues with the comctl32 V5
Irfan Ahmed, Senior Support Escalation Engineer brings this valuable knowledge to us. Recently, he was working on an issue where WPF application was crashing while showing the WPF PrintDialog and OS language set to local language for an example,Hebrew. The same application was working fine with English OS.
Following is the sample code and stack of failing thread in that scenario.
Sample code
public MainWindow()
{
InitializeComponent();
if (Thread.CurrentThread.CurrentCulture.Name == "he-IL")
{
FlowDirection = System.Windows.FlowDirection.RightToLeft;
}
}
private void button1_Click(object sender, RoutedEventArgs e)
{
PrintDialog pt = new PrintDialog();
pt.ShowDialog();
}

In recent past we have seen such problem with the comctl32 V5. Hence, he tested the application with Version 6.0 of comctl32. This is very easy to achieve. Below are steps.
For .NET – Visual Studio
· Add an “Application manifest file” in your project
· Un-comment the following lines of code and rebuild your application. It will use the Comctl32 version 6.0 now.
<dependency>
<dependentAssembly>
<assemblyIdentity
type="win32"
name="Microsoft.Windows.Common-Controls"
version="6.0.0.0"
processorArchitecture="*"
publicKeyToken="6595b64144ccf1df"
language="*"
/>
</dependentAssembly>
</dependency>
For VB 6.0 Application
1. Create a .txt file in the application folder and name it as “MyApp.exe.manifest.”
2. Copy the following content
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<assemblyIdentity
version="1.0.0.0"
processorArchitecture="X86"
name="CompanyName.ProductName.YourApp"
type="win32"
/>
<description>Your application description here.</description>
<dependency>
<dependentAssembly>
<assemblyIdentity
type="win32"
name="Microsoft.Windows.Common-Controls"
version="6.0.0.0"
processorArchitecture="X86"
publicKeyToken="6595b64144ccf1df"
language="*"
/>
</dependentAssembly>
</dependency>
</assembly>
Another alternative workaround for specific to printdialog crash issue in comctl32.dll v5 is using Windows Form PrintDialog. The below call in WPF application works fine.
System.Windows.Forms.PrintDialog pt = new System.Windows.Forms.PrintDialog();
Note: We have seen another similar issues with comctl32.dll V5 and would recommend to use comctl32.dll V6.0 and test if that helps you resolve issue related to comctl32.
