<SOLVED> TaskDialog problem Win98

I use the CJ TaskDialog control with markup and it works fine under Windows Xp, Vista, and 7.
However on a PC with Windows 98SE it does not display properly.  When the TaskDialog is called, there appears a messagebox headed "CJ Controls" and a button labelled OK.

Is this a known problem with Windows98 ?  Or is it likely to be a conflict with some other software on that PC, or limitation of its video card?
Any suggestions?

(It is not my PC, but this problem is reported by a client who wants to use my app).


SOLUTION:  removed the "encoding='UTF-8'  "  from the first line of XML and everything then works OK on all computers.

I manually set all parameters.

Thanks Oleg.  If you say it works OK with Win98 then that is all I need. I can tell the client it likely is his PC causing the problem :-)

Same problem (as last August) now reported with Windows 2003.

Customer has several PCs, and has tried my app on all of them. The PCs with WinXP and Win7 work fine, but on the Windows2003 PC the CJ TaskDialog does not display. Instead there is just a message box headed "CJcon~.ocx'  and an OK button.

I am just asking if anyone has any ideas what might be the cause or solution.

I have search all my VB code and cannot find any .useComCtl32 at all.

So I have not set this as far as I know.

Where would I put it if I want to try it?
Would this cause the symptom I describe?

The app on Win2003 PC is identical to the app that works perfectly on hundreds of other PCs.
Could there be some setting on that PC causing the problem?

Many thanks for your help.

Hi,

Hi,

I have 3 customers with this [problem.

CJ Sample works OK on all 3 customer computers.

So it seems problem must be something in MY code.

Thank you Oleg for good idea to try CJ sample.
I will now go to look for problem and tell you what I find (or else ask for more advice)

I have isolated the problem. Please can you help explain what is happening.

This works fine on Win98 PC.

This does not work in Win98 (but works OK in XP, Vista, 7)

Maybe it don't follow xsd file. Try to remove< xmlns=" & Chr$(34) & "http://www.codejock.com/schema/TDSchema.xsd"> part

OK, I have done this and sent it to customer to test.

(I am puzzled because your original TaskDialog Sample works OK on his PC. And your sample includes the Schema line... ??)

This code works on all PCs

    ' myXML = "<?xml version='1.0' encoding='UTF-8'?>"

    myXML = myXML & "<Dialogs xmlns='anyold123232312stringhere'>"
    myXML = myXML & "<Dialog Name='Dialog007' AllowCancel='true' EnableHyperlinks='true'
                    MessageBoxStyle='true'>"
    myXML = myXML & "<MainInstruction Image='*Warning'>
                    Do you want to open or save this file?</MainInstruction>"
    myXML = myXML & "<Content>A simple text message here</Content>"
    myXML = myXML & " <Buttons Default='2'> <Cancel/> <Button ID='100'>&amp;Open</Button>
                    <Button ID='101'>&amp;Save</Button> </Buttons>"
    myXML = myXML & "<Verification Checked='true'>&amp;Always ask before open</Verification>"
    myXML = myXML & "<Footer Image='*Shield'>While files from Internet can be useful,
                  some files can potentially harm your computer. If you do not trust the source,
                   do not open or save this file. &lt;a href='http://www.microsoft.com'&gt;
                    What's the risk?&lt;/a&gt;</Footer>"
    myXML = myXML & " </Dialog>"
    myXML = myXML & "</Dialogs>"

    TaskDialog1.CreateFromXML myXML, "Dialogs/Dialog[@Name='Dialog007']"
   
    TaskDialog1.ShowDialog

-----------------------------------------------------------------------------------------------------------
Note that the first line is commented out.

If I put the first line back, then the code works on MOST computers. But on a couple of WIN98 PCs this code does not work -- just gives CJ CONTROLS error.

If I create an error in the XML (eg. remove a > bracket) then I get this error on all PCs.
So it looks like something on the WIN98 PC is finding an error in the XML when that first line is there.  (But more modern PCs do not show error).

Do you know what files in Windows are used by TaskDialog to interpret the XML?  (I am thinking, maybe WIN98 has an old version .....)

If I leave off the first line for ALL computers, could this cause any problem??  (It seems to work OK)

Thanks Oleg. That works.

So the encoding='UTF-8' seems to cause a problem with old Win98 computer.

(Hmm... we still need to explain why the CJ Sample also works, even though it does include UTF-8, but I am not going to worry about that :-)

Thanks again for your help.
