Re: increase the speed when fetching bulk data from database using asp.net

It shouldn't take that long at all unless you have large text or image columns. I have a table with over 17000 rows and I can select all of them except the image column (which holds word documents) and it returns all 17000 in 1 second. However, if I select the file_blob column it takes several minutes.

So my suggestion is if you are selecting those columns, don't. Only select them when you need them. For example, the web app that uses this database only gets the .doc from the database when someone requests to download it.

Hi All,

I have a HTML Form with Text Field and Button.
The HTML Code is like this.

function validate()
{
if(login.txtname.value != "")
{
return true;
}
else
{
alert("Enter Your Name");
return false;
}
}

I have code for button send's click event in my codebehind file.

Now I want to validate txtname filed before submitting the data.
if function return true postback process should start.
otherwise alert message should display.

one more thing i don't want to use .net's validation controls.

You can change the form as follows:

<form id="login" method="post" onsubmit="return validate();" runat="server">
<input type="text" id="txtname" runat="server">
<input type="submit" id="send" runat="server">
</form>

or change your validate function to

function validate()
{
if(login.txtname.value != "")
{
document.forms[0].submit(); //submits the form
}
else
{ 
alert("Enter Your Name");
}
}

In my application there are two user types. Admin and other users.
In admin panel in the user listings I have a requirement which is : when i click a user i shall be seeing that users logged in pages in another window..ie validating that user's credential and enter his section..

The problem is occuring : when I open another users section then that session is overwriting that of mine..
Once the admin click on a user say X and enter his page in another window then immediately hsi(admin) session is getting overwritten by that of X..

Pls suggest some solutions.. Pls note: I am using Session state cookieless= false..which i cant make it true because that hampers security.. pls suggest some solutions other than this..

Thnx n advance

Well you can't and shouldn't be able to access his session.

I'm sure theres a way to trick the asp engine that you have his session ID, but its a hack at best.

Hi all

I want suggestions on following scenario

1.I have a image control on the web page.
2. I have FileUpload control
3. Button control to upload file to server

When user will select a .jpg file using file upload control, I want to display that image in the image control. Once user is satisfied with the image, he will upload it to server by clicking on Button control.

I have tried by implementing all events of FileUpload to refresh image control with the user selected image, but nothing worked out. can anyone pls guide me how can I refresh image control when user will select the file using file upload control.
Thanks a lot.

Save the file in your website and change the src to the location you saved the file.

how vital enterprise application are for proactive organizations leveraging collective synergy to think outside the box and formulate their key objectives into a win-win game plan with a quality-driven approach that focuses on empowering key players to drive-up their core competencies and increase expectations with an all-around initiative to drive up the bottom-line.

Or if you are storing the image in a database, you'll have to make a helper page that fetches images (like GetPic.aspx?id=SOMEID), with code like this in the page_load.

<br />
int id = Convert.ToInt32(Request.QueryString["id"]);<br />
<br />
        MyPics pic = new MyPics(id);<br />
<br />
        Response.ClearContent();<br />
        Response.ContentType = "image/jpeg";<br />
        Response.OutputStream.Write(pic.Image, 0, pic.Image.Length);<br />
        Response.End();<br />

Then after you upload the file, stick it in the database and get the id back you just set the ImageURL property of the asp image controls to "~/GetPic.aspx?id=NEWID" or whatever you called the file.

Downloading documents from an ASP.NET 2.0 page

Hello,

I have following code for providing download of file.

byte[] bytes = this.ContentController.GetFileContents(_filePath);
Response.Clear();
Response.AddHeader("Content-Disposition", "attachment;filename=Document.pdf" );
Response.AddHeader("Content-Length", bytes.Length.ToString());
Response.ContentType = "*/*";
Response.BinaryWrite(bytes);

This provides a messagebox on browser with Open/Save/Cancel button.
When I click on save, this saves the document on the disk, and I can open that.
But when I click on Open, this does not open the document. A prompt from PDF reader says, file not found.

How can I getrid of this problem.
Any help is appreciated.

Thanks in advance. Smile | :)

You could try putting a Response.Flush() at the end of your code there.

you may like to have file type check when you receive the uploaded file.
If incase system receive file other then TEXT, you can reject the file.

Hope this helps you!!!!

I think that FCKEditor contains some samples, you can learn from them.
Or you can check online documentation: http://wiki.fckeditor.net/

I can not send you my project, as it is not my, but belongs to a company I work for. If you can specify what exactly you would like to know (and didn't find in documentation Wink | ;)

), just write it down here and if I know, I'll give you an idea.

Yeah, and another knowledge base can be found on sourceforge: http://sourceforge.net/projects/fckeditor/

heh, you have to create a page, which contains FCKEditor control. On this page u can access content of editor by myFCKEditorControl.Value

creating page: http://wiki.fckeditor.net/Developer%27s_Guide/Integration/ASP.Net

keep in mind, that you have to disable request validation, otherwise .NET framework throws exception, something like 'Potentionly dangerous request' or so. you can do it in web.config, or in <%@ Page ... %> block

Save to a database is your job, just take html from control, wrap it into binary format and save it. Note that images are saved on server.

I don't remember if I saw error like this when developing my FCKEditor application, so I can not help u with it. But at least check if IIS user is allowed to write to a folder which contains images.

Again, I recomend u to read documentation, I gave you links in my previous post. It is very usefull, and I can not help you better.

But if you don't understand something, or can not find it, ask me

I'm sure you can have the same results using ASP.NET as using ASP.
But I can't help you with this error, as I don't know where it is raised. I suppose it is somewhere in a javascript, isn't it? You have to debug it (I know, debugging js is a pain Smile | :)

) and see where this error occures. I think it could be a problem with reading configuration files for FCKEditor, since it is xml error, but I'm not sure. Try to identify at least a file of this error origin. Then I can take a look in my code and see what can be wrong there.
