Hi, i'm not really sure what you want to achieve, but if you want to pass the content of the strpicture-variable to a javascript-function during the "onLoad" you could use hiddenfields. Just put strpicture into a hiddenfield of your asp-form and access the value of this field during the "onLoad". Should look like this (client-side):

function onload() {
value = document.getElementById("here goes the hiddenfield-name").value;
ShowPicture(value);
}

...

<body onload='javascript:onload()'>...

Hope this helps... Regards Sebastian

Or You can try this... by using RegisterStartupScript and pass the variable value from the code. public void Page_Load(Object sender, EventArgs e) { // Define the name and type of the client scripts on the page. String yourVariable = "yourVariable"; String csname1 = "PopupScript"; String csname2 = "ButtonClickScript"; Type cstype = this.GetType(); // Get a ClientScriptManager reference from the Page class. ClientScriptManager cs = Page.ClientScript; // Check to see if the startup script is already registered. if (!cs.IsStartupScriptRegistered(cstype, csname1)) { String cstext1 = "alert('Hello World');"; cs.RegisterStartupScript(cstype, csname1, cstext1, true); } // Check to see if the client script is already registered. if (!cs.IsClientScriptBlockRegistered(cstype, csname2)) { StringBuilder cstext2 = new StringBuilder(); cstext2.Append("script type=text/javascript; function DoClick("); cstext2.Append(yourVariable); cstext2.Append(") {"); cstext2.Append("Form1.Message.value='Text from client script.'} </"); cstext2.Append("script>"); cs.RegisterClientScriptBlock(cstype, csname2, cstext2.ToString(), false); } } I hope this helps...

In Java the technology is/was called liveconnect. The best manner to do it now would be to write to the document stream new data or to have Javascript make continuous calls to the server. In your case I would just write the assignment to the file.
