Problem with .ReadIDTag

Re: Problem with .ReadIDTag

Hi,

I am using XP Pro, but your post explains why it has *apparently* not worked. It seems OK with VBScript (I should have checked), but I am using PHP, which will be running as the default user, to access the info via COM objects. I have no real desire to elevate the privileges for PHP, so can I add the relevant key(s) in the registry for the default user?

Copy the reg keys from software\illustrate between the branches.

Re: Problem with .ReadIDTag

Hi,

Thanks, we seem to have success

I exported the Illustrate branch, renamed the keys and imported the .reg file to the default account.

Re: Problem with .ReadIDTag

I think you will have to use VB.NET to do this.

I think this Microsoft article is relevant to the original issue of Type mismatch when calling dMC.ReadIDTag: http://support.microsoft.com/kb/197956#top

SYMPTOMS
When passing a parameter to a COM Component's method in Active Server Pages (ASP), the following error occurs:

Microsoft VBScript runtime error '800a000d' Type mismatch

Or the value stored in the variable passed to the method is not changed.

CAUSE
VBScript will pass parameters to a method by value if the argument's data type is NOT declared as a variant and the parameter is passed by reference if the argument's data type is declared as variant by the method.

RESOLUTION
Parameters to be passed by reference to a method should always be declared as a variant data type by the method, while parameters to be passed by value can be declared as any type by the method.

Re: Problem with .ReadIDTag

This is what my COM object browser say the definition of ReadIDTag method is:
Sub ReadIDTag(File As String, Index As Long, pRetElement As String, pRetValue As String)

If I understand the MS article, I think the definition must be changed to:
Sub ReadIDTag(File As String, Index As Long, pRetElement As Variant, pRetValue As Variant)

Re: Problem with .ReadIDTag

VBScript only have Variant data types, passing a variant would be wrong as the scripting code is expecting an OLE string.

Re: Problem with .ReadIDTag

I'm just repeating what MS says on topic. Passing a variant should not prevent a well-written method to check the appropriateness and reasonableness of the data passed to it. I am not sure how to interpret your answer. Does this mean that dMC is not compatible with VBScript? If so, that might be important for some customers to know before purchasing.

Re: Problem with .ReadIDTag

That one function is not, we will be writing a new method for R13.

Re: Problem with .ReadIDTag

Thanks for the quick response. I look forward to R13. In the meantime, I have gotten tons of value and had fun using R12.4. It has helped me clean-up a number of issues with my music library already.

Re: Problem with .ReadIDTag

Has anything changed in R14? I have Windows 7 x64 running on Intel Core i7 (shows as 8 cores). But ReadIDTag does not return any value on 64 bit platform, although it works well on a 32 bit windows 7 platform.

I compiled the code inseveral different ways on Windows 7 box:
1. CPUAny, on 64 bit Windows 7 - does not work
2. CPUx86, on 64 bit Windows 7 - exception on dMC creation, of course
3. CPUAny, on Windows 7 32 bit - works

What gives?

Here is the sample code:

DMCSCRIPTINGLib.Converter dMC = new DMCSCRIPTINGLib.ConverterClass();

for (int i = 0; ; i++)
{
	string Element = "", TagVal = "";
	dMC.ReadIDTag(srcFile, i, ref Element, ref TagVal);
	if (Element.Length == 0)
		break;
	Console.WriteLine("\tReading Tag[{0}] '{1}:{2}'", i, Element, TagVal);
	dMC.WriteIDTag(destFile, Element, TagVal);
}

Re: Problem with .ReadIDTag

I can see why it is not working in x64, will address for R14.1

What is the new method to replace ReadIDTag, please? In R15 the only other I see is ReadIDTagElementValue, which returns a combined string.

Re: Problem with .ReadIDTag

It was .ReadIDTagElementValue

These functions have always returned multi artists combined.

Re: Problem with .ReadIDTag

OK, thanks.

These functions have always returned multi artists combined.

I was referring to the combination of Element and Value. Which is OK... until the separator crops up inside Element
