I have implemented captcha control in my webpage based on the article How to implement Captcha in ASP.Net.
It is working fine when running through the VS IDE, but when i deployed the website in IIS 8 (Windows 8.1) server the captcha image does not show.Â
I m using your Captcha Code [URL]. This code is working at local system but not working on Server Side. Captcha Image is not Displaying any Code.

How to implement captcha in ASP.NET. I've a strange scenario where the captcha letter is showing correctly but the background image(the black dots) is not displaying.I checked it by using firebug in firefox,to my surprise i found that an additional div(which i have not written) is enclosing the captcha,and its background color is set to white.This is how i placed the captcha inside the form tag in aspx page
<div id="divCaptcha">Â
<cc1:CaptchaControl ID="Captcha1" runat="server" CaptchaBackgroundNoise="none" CaptchaLength="5"
CaptchaWidth="200" CaptchaLineNoise="none" CaptchaMinTimeout="5"
CaptchaMaxTimeout="240"Â FontColor="#529E00" CaptchaHeight="60"/>Â Â Â </div>
This is what i got when i checked using the firebug
<div id="divCaptcha">
<div style="background-color:White;">
<img width="200" height="60" border="0" src="CaptchaImage.axd?guid=1e625862-4447-41ff-a6a5-86ad1e95261a">
</div></div>

I have implemented as writeen in the aritcle but the captcha image is not being shown when I run the application.why
I have two themes in my .Net application, both use the same background image. Both have an images folder with this image in them, both have style sheets. One works and one doesn't but ONLY when deployed in IIS in a Virtual Directory scenario so there is an added /MyApp/ directory.
I can't seem to even trick the one that doesn't work into finding the image. My style looks like this:
body
{
margin:0px;
font-family: Trebuchet MS, Verdana;
font-size: 12px;
font-style: normal;
background: #fff url(images/mainbg.jpg) repeat top left;
}
I have issue in Mathematical captcha, its not working in IIS,Image path not getting, it shows altertext "Captcha".
View 1 RepliesI am using the ASPNET_Captcha control for my login page. It works fine. However when i implement the forms authentication, the catcha image does not appear.Â
Do i need the location section in the web.config file? If yes can you share the details for the same.
I have a web site using Forms Authentication that downloads a PDF file specific to the user from a page. On the development server I have it working fine, on the live server it checks to see if the file exists and fails (correctly) if it doesn't, but does not load the Dialog Box to save/open/cancel if it does exist. Any ideas ? There are no events logged, the code is as follows and by the way I have tried various combos of WriteFile/TransmitFile as per other forum posts - many combos seem to work on development machine(!!) but fail on live...
Dim

As
New FileInfo(strReportPath) [code]....
Exception message: The remote host closed the connection. The error code is 0x800703E3.
I have created two asp.net pages, if x times the login fails, I want to call the captcha page (second page) in a popup window. How do I automatically call the second page as a popup window in the first page without using a hyperlink button?

View 10 RepliesI'm implementing captcha on my website like the one in [URL]. It is working fine while running on VS2008. However, not when uploaded on IIS. I think the image is being blocked by IIS.. anyone knows how to fix this?
View 1 RepliesI have a routine to display an image on an aspx page. The url for the image uses imagerender.aspx . This is simply an empty page with code behind:
myClass mysub = new Myclass(); // create class
Stream strm = mysub.DisplayImage(UserID); // call method to load bytes from db
byte[] buffer = new byte[2048];
int byteSeq = strm.Read(buffer, 0, 2048);
while (byteSeq > 0)
{
Context.Response.OutputStream.Write(buffer, 0, byteSeq);
byteSeq = strm.Read(buffer, 0, 2048);
}
Ok, this work fine when testing on my local machine, but when I move it to the live server, it comes up with an empty image box!
It looks like there must be a problem with security, maybe with ISS.
Does anyone know what changes I can make to fix this problem or what setting to change in IIS 7?
I want to have the captcha image validation where users need to enter the text shown in image.
View 1 Replies I have a web application running asp.net and SQL Server 2008.
When i run the site within VS2008, the captcha image works fine, but when i run the site via the internet i have no captcha image.
I used a custom captha inside my mvc application and it works perfectly fine in local but in production it isn't being generated. why is that?
I used the following statement for saving the image. do you think it is beacuse of that?

how you have implemented mathematics type captcha in comments sections in URL...I like to implement this type of captcha security, its more clean and user friendly.
View 1 RepliesI am really new her and to asp.net
In fact this is my first asp.net project and I really enjoyed it soo much
When I run the project, it worked form on my machine but when deployed on a remote server, it gives me error and I dont know what the problem is?
I have tried a number of things to no avail
The project is located at http://soft.turingz.com
It uses mysql and my host said they have the .net connector installed but yet .
We have deployed an application in iis 6.o. We set cache for 1 hr in that application so that the updated data in the back-end will be visible by the user after 1 hr. If the requested data not available in cache it will fetch from database directly.
Is there any way that I can clear this cache in between 1 hr for some of our testing.
Resetting the website and app pool and deleting temp asp.net files didn't work, I have tested that.
I'm trying to deply a 3.5 Net application developed in VS Web Express and built using the asp compiler. This works fine when tested using an eval version of Win 2008 Standard server on a VM. However when installing on a production Win 2008 Standard server it fails with the message can not load assembly as it has not been signed or the signature does not match. How come this works in one and not the other? The live server has symantec AV installed and running? If this the reason? Have a bit of knowledge ( as all devlopers do) of OS's but am totally stumped by this. If I could even replicate it on the development machine would allow me to move forward. Do i need full Vis Studio? Do I need to sign the DLLs?

If same web application is deployed on three different servers, which things we need to take care of and what things should be common amonges all three?
View 3 RepliesThis may be a dumb question, but I've got a DLL that I compile and reference locally in a web site project and everything runs just fine. When I deploy this solution to the test server, I get an "Object reference not set to an instance of an object." error and the stack trace displays the files with their paths that are causing the error. The thing is, the paths being displayed are the absolute path as they existed on my development machine. Here's the stack trace:.........................
