View 3 RepliesI have deployed my application in the test server, and did the settings correctly, but my websites pages are getting refreshed automatically in less than 2 mins.
View 2 RepliesI have written a website and let the user upload their photo. It also resizes the picture to 400 x 400 and crops automatically to the center part of the picture. All of this works good but each file is about 355K each for JPG and PNG file formats. I just tried GIF and it is 49K but the picture is grainy when saved this way. Is there any way I can get the picture to a smaller file size with keeping it at 400 x 400? I really thought PNG would be the way to go and was surprised by it being the same as jpg. I don't want to lower the quality either for JPG files.
View 1 RepliesWhen uploading a new DLL for a large web application (dll is around 1mb) IIS throws an error because the DLL is 'in-use', meaning the website is down while the DLL is being uploaded. Is there a way to stop this behaviour?
Also, although I am using Web Applications, not Web Sites, whenever I upload a new DLL it still takes a while for IIS to restart after a fresh upload. I thought this wait was generally only for websites as they need to be compiled by IIS, not Web Applications?
how to upload files to the physical location of the server. It is possible using file upload control that i know. But i want to avoid the external postbacking of the page. For e.g exactly like what in the yahoo mail did.
In yahoo mail latest version if you attach a file that won't post back and attach that file in to server. What is the technology behind that?

I have a Reportviewer control linked to Report1.rdlc with a matrix with Drillthrough activiated.When I click the "+" buttons to drill through, even I enclosed the control with Penal etc it still caused the whole page refreshed which is annoying.

I have created a page with a gridview in asp.net that displays the records of a database table and allows users to delete checked records by clicking on a delete button. After I delete a record and I try to refresh the page from the browser (I am using mozilla)I get the follow message:
"To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier."
and if I click resend another record is deleted automatically. Even though I am reloading the gridview after the deletion the application executes again the onclick event of the delete button is executed and the gridview things that there is a checkedbox selected so the code executes my delete function again.
Is there any way to get rid of these behavior. I have been trying quit a few things but nothing works for me.
Some say it is not a bug it is default in asp.net. but for me it is a bug in logic. When you say refresh it should be reload the component that you are refreshing. But in asp.net i notice that they recalling all activity and viewstate like event and data that are triggered in the previous postback. My opinion it is a redo not refresh. this is only my observation on the issue dont hate me on this microsoft fan.

private
static string __VIEWSTATE_FETCH;

EventArgs e){

I'm currently developing a web application where everything works fine in the visual studio web server. It authenticates the user, access the database, writes to it, etc.
After I wrestled yesterday to publish it to my local iis, a subject I admit I have little to no experience of doing, suddenly the membership of the website started to not authenticate the users.
At first I suspected maybe the app wasn't accessing SQLServer, or that the data with the users I had in the asp.net membership database was erased when I uploaded the website.
So I stopped iis, i attached the db file to my local sql server, and I can see that all the users are there just like I uploaded them. I also can see the website can access another database with micellaneous contents just fine.
The loging controls don't tell me there's any problem either, they just show a message telling the user that the login attempt wasn't successful.
So, here's what I remember I did to make the app work as it wasn't even doing that when I first uploaded it.
I used the asp.net_regiis tool to copy website scripts to the website.
aspnet_regiis -sn <path>
then I deleted the website, uploaded again from VS. this time it shows in the browser but it doesn't authenticate the users.
The application isn't precompiled, I just uploaded it.
i am using a file uploader to upload files. Now when i am using this on a mobile emulator with default browser IE it is uploading only those files whose name is less than 6 character. the files with name more than 6 character is not uploading through mobile emulator or mobile phone (PDA). I need this solution very soon.

I have a special requirement with regards to popping up a MsgBox in ASP.Net. There seems to be various solutions across the Internet using the Javascript confirm box, and passes the response to a hidden control, from which VB.Net can the read and further respond ...but the Javascript code is initialted by a button on the ASP.Net Form. I want to be able to pop-up a MsgBox in the middle of my VB code-behind using the Javascript trick, which passes the result to the hidden control, which can then be read by VB.Net .... the problem is that the page has not refreshed and the hidden control still contains the value from the previous Submit .... I'll attach my code. If anyone can come up with a solution, will you have achieved the impossible!

View 2 Replieswhile uploading the file on the local host it works fine.but the same coding does not work on the webserver. is there anything to do with the foldr read and write permissions.i m using the server.map for finding the path of the browsed file.
protected void btnLogin_Click(object sender, EventArgs e)
{
try
{
string fold = "images";
string Name = FileUpload1.FileName;
sring path = Server.MapPath("~" + "/" + fold + "/" + Name);

i hv not used any database for storing the path of the image.
I have a Web application in which I'm trying to use the new AJAX AsyncFileUpload control. I want to use it in the ModalPopupExtender, and I want to embed these two AJAX controls in a user control (photo_upload.ascx) for re-use in different parts of the application. (I understand that this wasn't possible with the older FileUpload control but that it is with this most recent AJAX tool.)
Presently, I merely redirect the user to an upload.aspx page that includes the photo_upload.ascx control (see the sequential screenshots in the attached image); but while this way of doing things "works," it becomes very confusing for the user who has already clicked an upload button or two. In other words, when the "Add Yours" button is clicked, the panel with the "(1) Upload Photo" button unhides; and when the Upload Photo button is then clicked, the user is redirected to the control in the bottom screen. I would gladly bypass the 1, 2, 3 steps in the second screen after the "Add Yours" button is clicked and redirect straightway to the upload control (in the bottom screen, which I will like to be in a ModalPopupExtender), but I also need a way for them to enter a caption that will go with the uploaded photo.

My VB code for the above steps is included below. I would appreciate any fresh ideas on how to accomplish my above objectives.
