I have two arraylists, each record in each arraylist has the same 2 fields
Any ideas what I could code to see if the value of a field in a given row in one arraylist is the same as the value of a field in a row in the the other arraylist?
|
|
|
|
|
if (((objectType)firstArr(0)).fieldName == ((objectType)secondArr(0)).fieldName)
{
}
|
|
|
|
|
I'm not understanding whats needed for object type
my arrays have two fields in each record; ID number and name, both are strings.
Also the only extention that the system lets me put after my arraylist name is .GetType
(objectType)firstArr(0)).GetType

Replace objectType with the type of object you have stored in the ArrayList, or better yet if you use .NET 2.0 use List<objectType> rather than ArrayList. So for example, if you have a DataRow stored in the ArrayList, do this:
ArrayList arrList1, arrList2;
//stuff to instantiate your arraylists
if (((DataRow)arrList1[0])[0].ToString() == ((DataRow)arrList2[0])[0].ToString())
{
// do stuff
}
But with Lists do like this:
List<DataRow> list1, list2;
//stuff to instantiate your lists
if (list1[0][0].ToString() == list2[0][0].ToString())
//do stuff

Hi,
What is the difference between updating data in dataset using Adapter.update()
and using CommandBuilder.UpdateCommand()?
Thanks in advance

Hmmm... I don't really know.
But you may be able to find out using a tool like Lutz Roeder's Reflector[^]. It lets you inspect assemblies and decompiled methods.

Hi,
I'm looking to find some code or software, that will allow me to generate an image that will represent the plan view of a building i.e. 5 racks labelled A-E, The rack with the that plan must be hyperlinks that will allow for the viewing of the items stored within that location,
To make things even harder for me, the image must be editable via the web. i.e the user must be able to move, resize racks within the image etc
I know i'm asking for alot but miracles can happen 
Thank you
GRD
To those who believe nothing is impossible ....

How can you use / display 5000 records in ASP.Net? You really shouldn't be returning that many records in a web browser there is no way to speed it up, what are you trying to accomplish with that many records?
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. But of course, that's all a "high level" overview of things

As Todd said that's far too much data to be retrieving. Instead you must find methods to retrieve chunks of smaller sets of data at a time as and only if required by the user in their interface.
If you truly need a lot of data at the server end only then you can cache it at the server, however you should never send that much data out to the client.
Consider using an out of band reqeust (AJAX) to retrieve important portions only, i.e. some sort of paging scheme or a typeahead combo scheme if it's a combo.
In the app I'm working on now, I try to limit each request to no more than 50 rows of data in grids and 20 in combo boxes. Any more and the user can page the grid or combo and it's filled using an out of band ajax request.

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();
}
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.

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.

Dim policy As Policy
Dim policyToken As Guid
policyToken = Guid.NewGuid
Session.Add(policyToken.ToString, policy)
Response.Redirect("UploadFile.aspx?PolicyToken=" & policyToken.ToString)

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.
