Edited (x2):

Something like this:

<script type="text/javascript">
var queueSize = 0;
function startUpload(){
    if (queueSize == 0) {
        alert("Please select a file first.");
    } else {
        $("#fileUpload").fileUploadStart();
    }
}
</script>
<script type="text/javascript">
$("#fileUpload").fileUpload({
    onCancel: function (a, b, c, d) {
        queueSize = d.fileCount;
    },
    onClearQueue: function (a, b) {
        queueSize = b.fileCount;
    },
    onSelectOnce: function (a, b) {
        queueSize = b.fileCount;
    },
    onAllComplete: function () {      
        queueSize = 0;
    },
    onComplete: function (a, b ,c, d, e) {
        queueSize = 0;
    },
});
</script>

Which you would call with:

startUpload();

Thanks for replay, but if file is empty function don't go in: $("#fileInput2").uploadify({ });

You mean if the file you are uploading is empty, that event doesn't fire? What error are you getting?

I mean, if i don't select any file and push button Upload Files. I wish see error.

Thank you, but I have now done so. I want when pressed send button without marking anything notified to report user (you must select, or etc. ). I hope to understand my problem

What I am saying is that you don't need a send button at all. Only a browse. Do you have a demo we could look at?

I did this in much simpler way. Add a div and associate it with uploadify 'queueId'

<asp:FileUpload name="fuFiles" ID="fuFiles" runat="server" />
                        <div id="fuItemsQueue" class="fuItemsQueue">
                        </div>

$("#<%=fuFiles.ClientID %>").uploadify({

                'swf': '../Scripts/uploadify.swf',
                'queueID': 'fuItemsQueue',
.....
            });

Just on the OnCancel Event just count the number of Divs left.

'onCancel': function () {

                    var queueCount = $("#fuItemsQueue > div").size();

                    if (queueCount = 1) {
                        DisableUploadButtons();
                    }
                }

And done!! :)
