Internet Printing (ReadyState always 4)

I'd suggest looking at the ReadyStateChange event if you have not already done so. You'll want to set the BitmapDataPath and then wait for this event to fire. Once the event fires, you can then check to see that the ReadyState is equal to "READYSTATE_COMPLETE". There are examples in the documentation on using this event.

I have attached a short example of how to use the ReadyStateChange event in Javascript.

Hi the example which you have given is very helpful for sure.
But i have a similar problem. I am trying to assign LEAD1.AnnDataPath also as soon as LEAD1.BitMapDataPath is set. I am able to load bitmappath and then go for setting anndatapath. But after setting anndatapath i am unable to check for the ready state value of the ready state change event called for anndatapath event.
Could you please send me the code snippet or example which would also load anndatapath also

Hello Naresh,

These methods, BitmapDataPath and AnnDataPath, are asynchronous. In order to process both, you're going to need to block the page from executing any further before processing the second of the two methods.

Have you tried implementing something like the following?

"

function pausecomp(millis)
{
var date = new Date();
var curDate = nul\;

do { curDate = new Date(); }
while(curDate-date

while(number of pages ){
LEAD1.BitmapDataPath = "some_bitmap_file.bmp";
m_bBitmapDataPathSet = true\;
while(m_bBitmapDataPathSet)
pausecomp(500)\;
LEAD1.AnnDataPath = "some_bitmap_file.ann";
m_bAnnDataPathSet = true;
while(m_bAnnDataPathSet)
pausecomp(500);
...
}"


If you are having trouble with implementing this, please post a small sample project which illustrates this issue so that I can continue to help you with it. Here are a few guidelines about posting sample projects:

NOTE: If you are attaching a project or file to the forums...
1.) Zip the file(s) up.
2.) Make sure it is less than 5 MB. If it is larger, please send an email to support@leadtools.com and we'll send you FTP instructions.
3.) Remove ANY AND ALL unlock codes and LEADTOOLS DLLs.
4.) Do not click the preview button, the attachment will not show up when you post it.

If you do not wish to post your file(s) on the forum since they are publically viewable, please send an email to support@leadtools.com and make sure that you include a link to this forum post.

Sorry for bringing back the dead but I am having a similar problem as the original poster.

We are using a httphandler to pull the document. Some documents are on cart and take a while to pull. For some reason during this time leadtool's readystate is being set to 4 before the document is actually loaded.

I tried catching it by saying do nothing if the Lead1.InfoFormat != 0 (and wait until it is a non zero value, but I get a "ltocx14n, LEAD Error: Invalid file format"). And I also tried your example of having a hidden leadtool open the document then pass it to the main one. Both are failing.

Version=14,5,0,37

Any suggestions?

I should have done some follow up to begin with.  Note that the ready state is always 4 because from my understanding the ready state only applies to the control as is is being loaded to the page.  Prior to the control being loaded on the page, is the only time I have seen the ready state anything other than 4.

My solution has been to load the image to the control and then test the bitmap property.  When the bitmap property is > 0 (valid handle obtained) then the image is finished loading.

function Main()
{
  LoadImage("foo.jpg");
  DoStuff();
};
function LoadImage(imgSrc)
{
  Lead.Bitmap = 0;
  Lead.BitmapDataPath = imgScr;
};
function DoStuff()
{
  if(Lead.Bitmap < 1)
  {
    setTimeout("DoStuff()",50);
    return;
  }
  ...//continue processing
};

Hello Quasney,

The invalid file format error generally means that either the file filter dlls couldn't be found to load the image, or LEADTOOLS can't load the image either due to corruption or the format isn't supported at all.

To find out which the problem is, I would suggest trying to load the image with our main pre-compiled demo that ships with the SDK. If you can load the image with our main demo, than the issue is with the filter dlls. If you can't load it with our main demo, then we'll need to take a closer look at the image to see what the issue is with it and our SDK.

Your dlls are also very old. I would recommend sending an email to support@leadtools.com with the following information so we can send you the latest dlls to test with:
1. The company you work for
2. The LEADTOOLS serial number/numbers you own (if you are evaluating, just say so)
3. The name/names of the developer/developers using the serial number/numbers
4. A link to this forum post


Javd,
Thank you for posting back as well.
