In javascript I have an image which I set the .src at runtime in javascript. The .src points to a asp.net page with a few values as querystring parameteres that I want t capture on the server. this page has empty content. In code behind in the page load I need to generate the smallest image possible and return it as the response. how do I generate a small image and return it in the response?

View 1 RepliesI am using dynamic data entities linq to sql project. For my test project I have one table, with 10 columns and a single primary key for example. Almost all the columns are varchars.I can get the basic project up and running fine - update, delete, insert etc.ince it has no foreign keys, there are no search filters rendered. I was wondering if there was an easy way to generate a set of filters for the columns for this table. So a First name and last name search box. Is there a way to generate these filters for chosen columns and is there a way to generate these for all the columns
for example, above each of the columns in the grid there might be a text box ( I am not too fussed where the text boxes are rendered as such). Each of the text boxes will act as a filter for that column (doing a SQL 'like')

My asp.net page dynamically displays 207 questions (I can't control this). Each question have 10 validators. When ASP renders the page it creates following three lines for each validator:
var qsnQuestionSet_adult_qcQuestion_1_vldMaxAnswersValidator = document.all ? document.all["qsnQuestionSet_adult_qcQuestion_1_vldMaxAnswersValidator"] : document.getElementById("qsnQuestionSet_adult_qcQuestion_1_vldMaxAnswersValidator");
qsnQuestionSet_adult_qcQuestion_1_vldMaxAnswersValidator.display = "Dynamic";
qsnQuestionSet_adult_qcQuestion_1_vldMaxAnswersValidator.evaluationfunction = "CustomValidatorEvaluateIsValid";
Althrough these three lines are just 4kb you can imagine that 4*10*207 is quite a lot. How can I mark all validators as dynamic and set evaluationfunction to same value without asp generating the line for me?
I've developed a component which processes online payments. At a specific point the user must be redirected to the selected acquirer web site for authentication. The acquirer itself suggests that there should be a web page which does it. Something such as the following,
<!--TakeOff.aspx-->
<html xmlns="[URL]">
<head id="Head1" runat="server">
<title>@</title>
<script type="text/javascript">
function Go() {
form1.submit();
}
</script>
</head>
<body onload="Go();">
<form id="form1" runat="server" method="post" action="/...">
<div>
<asp:HiddenField ID="MID" runat="server" />
<asp:HiddenField ID="Amount" runat="server" />
<asp:HiddenField ID="ResNum" runat="server" />
<asp:HiddenField ID="RedirectURL" runat="server" />
</div>
</form>
</body>
</html>
This page redirects the user and posts required arguments to the acquirer's web site. Prior to this page there is another page with a payment button (for example). In the click event of the payment button my component is instantiated and required calculation is done. Something such as the following,
protected void btnPayment_Click(object sender, EventArgs e)
{
try
{
var paymentProcessor = new NS.PaymentProcessor(/*required arguments*/);
/*...*/
NS.Result result = paymentProcessor.Calc();
Session.Add("PaymentProcessResult", result);
Response.Redirect("TakeOff.aspx");
}
catch (Exception p)
{
throw p;
}
}
What I'm going to do is to generate [TakeOff.aspx] page at run-time by the payment processor component instead of having static page (I mean aspx pages that are generated during development phase). The reason why is that we may have different acquirers and each acquirer requires its own arguments to be posted. So if the payment processor component generates aspx or even html pages at run-time we do not need recompile and redeploy the web application.
My problem is that I do not know how to generate aspx pages at run-time. I'm not an ASP.NET guru and all efforts that I've made using HttpResponse were in vain as the original page does not transfer the control to the generated page.
I'm no expert with Image controls, or dynamically adding anything, but I seem to have some problem when dynamically adding image controls
When the page loads the images are "there", but they don't actually show an image...just an image "box" I guess you could call it. It's not the "broken" image or "invalid" image display, but a friendlier one that doesn't make sense to me why it's there.
I look at the page's source and literally everything's fine, but I'm not sure what's going wrong. I can show you my code, and hopefully someone will point out the dumb thing I'm doing wrong:
[Code]....
[Code]....
So, it takes all the .JPG files in the folder "Pictures" of my project's folder and creates an Image control to be put into Panel1 with the ImageURL as its filename (with Directory Path) and even set the ID to its filename (so no duplicate IDs). Again, the source is exactly how it should be, but no image is shown.
I want to implement a response time monitor in a ASP.Net application. This monitor has to calculate the average response time during 2 secs. Whats the performance counter i can use. I tried ASP.NET ApplicationsRequests/Sec but did not work. Whats the best way to do this. I am using the default server formed by VS2005 for development, does this affect the performance counter programming?
Where should I implement the logic? Global.ASAX? in every 2 sec i want to check this value and make some decisions.
In addition, what are the parameters I can alter in a ASP.Net application at runtime to improve perfromance. How can I change them?

I may want ASP.Net to handle the "sampleimage.gif", so that it can be fetched from database server, using HttpResponse.Write()

Is is possible to update an image on an HTML page using the response stream of an ASP.NET Generic Handler? For example, if I have the following code on a handler: [URL]
public void ProcessRequest (HttpContext context) {
context.Response.ContentType = "image/png";
context.Response.WriteFile("~/images/test.png");
}
How can I call the handler in jQuery, using .ajax, and set an image on the page equal to the image that is returned by the Handler? I am ignoring the query string variable at the moment as I just want to get this working. Secondly, if I can do above, how can I loop through all of DIVs on the page that are of class "content", select a guid out of a hidden field to use as my query string parameter, and update the associated image within the same content DIV tag? A content div tag would look as follows:
<div class="content">
<asp:TextBox runat="server" Id="HiddenField_1" Value="C142E68F-B118-4565-9A9E-B2347F0B6D5B"/>
<img src="#"/>
</div>
<div class="content">
<asp:TextBox runat="server" Id="HiddenField_2" Value="GJ38AD23-B118-4565-9A9E-B2347F0B6D5B"/>
<img src="#"/>
</div>
I would like to have all the images updated on a periodic interval, so essentially, as a quick recap, I would need to have: A loop through all of my DIVs of class "content", occuring every n. seconds. Extractation the GUID from the hidden field. A call to my ASHX handler to get the updated image. Set the returned image to the corrisponding image on the page. Is this something that would be difficult to achieve? If not, what would I need to do to make this function in the above manner?

I've created 2 web user controls. A = User control that displays an image, and B is the user control that hosts A. I'm trying to stream an array of bytes to A, but it seems like the Response.BinaryWrite method completely overwrites any heirachial controls (I can't see any of B's other controls besides the image).
How do I get A to just display the image from the byte stream? It doesn't come from a database, it's an image I created on the fly.

So I'm trying to make my own forum signature generator for some friends, and I've gotten most of the work done. My real issue now is refreshing the information when the image is requested from my server.
Basically, I'm looking for someone to push me in the right direction on how to have the image refresh from the datasource when it gets requested, but only if it has been more than 5 minutes to prevent an overload.
I have a report that is supposed to have a check box selected if the Lead value is -1. Else it is supposed to be unchecked. I already know that rdlc's do not have check boxes. Now I have the two check box images in a ftp directory, one image looks selected and the other looks unselected. I have the problem in my if statement when I render the report it gives me the error of No Colons. But I need colons 'ftp://' in my IIF Statement.
