Read the image in a byte[] and assign it to the session variable.

As manash sugguested you can store image as byte array in the session variable. But why you are storing image in session variable ? Did you thing about size of session variable?

Hello,

I am trying to send email from Microsoft outlook from my application, and I wrote following code :

string stSubject="";
string stTo="";
string stCC="";
string stAttachmentFileName = "";
string stDisplayName = "";
string stBody = "";

ApplicationClass oApplicationClass = new ApplicationClass();
NameSpace oNS = null;
MailItem oMailItem= (MailItem)oApplicationClass.CreateItem(OlItemType.olMailItem);
//stSubject is the mail subject
oMailItem.Subject = stSubject;
//stTo is the email to address
// oMailItem.From = "m.r.chavan@amc.nl";
oMailItem.To = "aa@aa.nl";

oMailItem.CC = "bb@bb.nl";
oMailItem.BodyFormat = OlBodyFormat.olFormatHTML;
//if you want it in the plain format, you can set body format as oMailItem.BodyFormat = Outlook.OlBodyFormat.olFormatPlain;
oMailItem.HTMLBody = stBody;
//oMailItem.Attachments.Add(stAttachmentFileName,(int)OlAttachmentType.olByValue,stBody.Length+1,stDisplayName);
oMailItem.Display(true);

Can anybody tell me how can i set the oMailItem.From in the mail, I know that the outlook is taking the default user account for mailing, but can I set the FROM property ?

You should system.net.mail to send mail from server code in asp.net.

I doubt very much you can mail from a clients machine.

I didn't get any requirements for the signature

You are an ignorant moron. You've been told the answer, several times now. The best you can do, is to create a bitmap with a diagonal line in it, and use an img tag. You can't draw lines, HTML does not support that, although SVG does.

I haven't used 1.1 in a long time. But the error suggest that it is looking for a server side method return.

Therefore, I suggesting using button.Attributes.add("OnClick", "return md5auth(Txt_password)"); in your server side code. Perhaps in page_load.

The first clue is that you're doing two different things. In the first case you're adding an onclick, which is called on the client', in the second, you set OnClick, which tries to call a method on the server.

Turning off validateRequest for a user control [modified]

5-Jun-09 0:37

Hi All,

I am writing a user control which needs to allow users to enter simple HTML tags into a text box (strong, emphasis etc). Obviously, ASP.Net stops this by default.

If I were to write a page to do this, I know that I could use ValidateRequest="false" in the Page Attribute (this is all I can find on Google, which is frustrating as I already knew about it!)

The problem is that I am trying to do this in a single user control and do not have access to either the Web Config for the entire site or the code of the pages that this control will be used on.

Does anybody know of a way to do this? Or can anybody point me towards an article that solves the same issue?

Thanks,
Chris

[Edit: I can't use AJAX, so no AJAX solutions please!]

Strange Behaviour of Crystal Report

Hello,
I have created one crystal report in VS 2005. Its datasource is ref cursur returned by oracle stored procedure and it is working fine except one formula filed which i have code like following:
Here CURSPKG_JOIN is the name of oracle package and
OPEN_JOIN_CURSOR1 is the name of stored procedure.

Name of formula field is:finalres

iif({CURSPKG_JOIN.OPEN_JOIN_CURSOR1.R1}='G'
or {CURSPKG_JOIN.OPEN_JOIN_CURSOR1.R2}='G'
or {CURSPKG_JOIN.OPEN_JOIN_CURSOR1.R3}='G'
or {CURSPKG_JOIN.OPEN_JOIN_CURSOR1.R4}='G'
or {CURSPKG_JOIN.OPEN_JOIN_CURSOR1.R5}='G'
or {CURSPKG_JOIN.OPEN_JOIN_CURSOR1.R6}='G',
iif({CURSPKG_JOIN.OPEN_JOIN_CURSOR1.FR}='1','FIRST DIVISION BY GRACE',
iif({CURSPKG_JOIN.OPEN_JOIN_CURSOR1.FR}='2','SECOND DIVISION BY GRACE',
iif({CURSPKG_JOIN.OPEN_JOIN_CURSOR1.FR}='3','THIRED DIVISION BY GRACE',
iif({CURSPKG_JOIN.OPEN_JOIN_CURSOR1.FR}='C','SUPPLEMENTARY',
iif({CURSPKG_JOIN.OPEN_JOIN_CURSOR1.FR}='F','FAILED',
iif({CURSPKG_JOIN.OPEN_JOIN_CURSOR1.FR}='P','PASSED',
iif({CURSPKG_JOIN.OPEN_JOIN_CURSOR1.FR}='Z','PARTIALLY PASSED',
'xx')))))))
,
iif({CURSPKG_JOIN.OPEN_JOIN_CURSOR1.FR}='1','FIRST DIVISION',
iif({CURSPKG_JOIN.OPEN_JOIN_CURSOR1.FR}='2','SECOND DIVISION',
iif({CURSPKG_JOIN.OPEN_JOIN_CURSOR1.FR}='3','THIRED DIVISION',
iif({CURSPKG_JOIN.OPEN_JOIN_CURSOR1.FR}='C','SUPPLEMENTARY',
iif({CURSPKG_JOIN.OPEN_JOIN_CURSOR1.FR}='F','FAILED',
iif({CURSPKG_JOIN.OPEN_JOIN_CURSOR1.FR}='P','PASSED',
iif({CURSPKG_JOIN.OPEN_JOIN_CURSOR1.FR}='Z','PARTIALLY PASSED',
'yy'))))))))

and i put this formula filed on to the report; but it is printing the required result at somewhere and somwhere no print (even, i have given the false part i.e. 'xx' and 'yy') even with the same condition. I have double checked the data in the table and just for checking; i have placed the FR column on the report, which is carrying right value though. FR column is varchar2 length 1 character.

Please guide me where i am missing....!
Thanks & Regards

TabControl - Active Tab Index Question

Hi all,

I have a page in which I have the Ajax tab control with 4 tabs. Within each tab control I have a gridview with one of its field as hyperlink. Now when I click on the hyperlink it goes to Page1.aspx. I have a back button in that page which takes me back to the parent page, but if I clicked the hyper link from tab 3, on returning through the back button the active tab resets to tab 1. Is there any way I can remember the current active tab from which the hyperlink was clicked on returning through the back button?? Confused | :confused:

I have tried passing it through the query string, and yes it does work, but as soon as I navigate to another tab on the same page and do a little bit of paging the query string still remains in the url and causes the tab to navigate back to the original position. Confused | :confused:

Thanks in advance..
Kind regards,

render ListBox

I have a listbox that's values populate from a SQL datasource. In the form on the page there is also a gridView and when it's value changes the items in the listbox should change accordingly (well, technically, it should changes a sql parameter that updates the listbox).
In another SQL query I have an array of values. I then turn that into a string array. The values in that string array correspond to values in the listbox I'd like selected. This is where I'm running into trouble - how do I get the listbox items to be selected? I can't find a way to update the listbox.

Does anyone has any suggestions?

Any help is appreciated!
Thank you!!!

If you're doing a postback, just inject the HTML to select the item. If you're using a server control, you can probably just set properties on the control.

Without knowing how you're doing this ( AJAX? ) ,it's hard to say more.

Can anyone help

The goal of this project is to develop a website where users can enrol in a
chess competition and play each other until the final winner is decided.
The website will require an administrator to set up the competitions. Users
can then enrol in a competition by clicking on the appropriate link and
logging on. When the competition has sufficient players enrolled, players
are randomly selected to play each other in the initial round. Winners and
losers are then appropriately selected to play each other until the winner is
decided. To inform users that it is their turn to make a move, the server
should notify players via email. Winners, losers and new competition
announcements are also notified via email.
Optionally, the game can have drag and drop interactivity for players to
make moves. Players can also nominate to play against one of a number
of chess engine on the website if they want. The Administrator has the
option to have advertisements sent with the notification email messages.
Whenever an advertisement is sent to a player via email the advertiser's
account is charged a nominal rate, say 2c per add.
The above specifications should be taken as a guide only and may be
varied by making a request to the project supervisor. The group is
permitted to use an open source chess engine on this project (with
acknowledgments). e.g.

I assume the group you're part of has been assigned with this task as homework. If your attempt at research is to post it here and hope someone will do ( a LOT ) of work for you, then you're going to fail, and deservedly so.
