I don't know why this bugged me, but it does.
MagForJ wrote: if(abrev.equals("INTC")) str = "Intel Corporation";
else if(abrev.equals("GOOG")) str = "Google Inc";
Why abbreviate "Incorporated" in "Google Inc" but not "Corporation" (Corp) in "Intel Corporation"?

I'd definitely make it data-driven if I were you. Whether or not you should just add a column to an existing table is another matter.
In this particular case I think I'd have a look to see if I could get the data from somewhere and go from there. For example, there may be a free web service that let's you retrieve this. (This could be done at run-time, but web services are quite slow though; you probably don't want to look up a code at a time for a collection, for example.)
If you can get the data, storing it in a new table has some benefits: The descriptive string can potentially be sizeable, and adding a large column to any table, especially a small table (I've no idea what row sizes you have here), can have a significant impact on row size and thus on performance. I don't know what DB you're working with, but SQL Server has 8K pages and yet I've seen a "transaction" table (storing financial transactions, not database transactions!) that had a column defined as nvarchar(500) - that's a 1000 bytes just for this one column. That table could have millions of rows, but SQL Server couldn't get more than 6 records per page thanks to this horrible design error.
However you store the data, if it's not too substantial and you need raw speed, load it into a cache once and you should get great results.

how to add controls to webform without using placeholder or panel
|
|
|
|
|
Simple.
Solution 1: Add directly to the Page Control
TextBox txt = new TextBox();
txt.ID = "txt1";
this.Page.Form.Controls.Add(txt);
Solution 2:
Create a DIV tag with an ID and Runat = 'Server'
In the code behind, add the dynamic control to the DIV which inturn will be added to the Page Control
TextBox txt = new TextBox();
txt.ID = "txt1";
divAddDynamicControlsHere.Controls.Add(txt);
this.Page.Form.Controls.Add(divAddDynamicControlsHere);
Solution 3: Create a Table with TR & TD. Expose the TD's Id and Runat='Server'
<table>
<tr>
<td id="tdAddDynamicControlsHere" runat="server"></td>
</tr>
</table>
In the code behind, add the dynamic control to the TD which inturn will be added to the Page Control
TextBox txt = new TextBox();
txt.ID = "txt1";
tdAddDynamicControlsHere.Controls.Add(txt);
this.Page.Form.Controls.Add(divAddDynamicControlsHere);
Solution 4: Use literal control
<asp:literal id="LitDynamicControl" runat="server">
In code behind
string controlText = "<html><head></head>";
controlText += "<body><input type='txt' id='txt'></body></html>";
LitDynamicControl.Text = controlText;
Solution 5: Well you know, PLACEHOLDER CONTROL/PANEL

Hi,
I have developed an application which contains two projects.
It uses xml files which are located inside the bin folder of one of the projects.
When going through the click once, how do I tell the setup to use the xml files inside the bin folder of the project? i.e. Is there a place where I can include the xml files in the click once?
Thanks

If there already exist some text in textBox, then
restrict user, so user can not delete/modify that text, but can add(append) text in to textBox. How to do this?
Soppose:
"Quick brown fox jumps" (already present in text box)
so, user can only append text, but can't modify previous text.
like:
"Quick brown fox jumps ......(only from here he can enter/append)"
regards.

Try handling the KeyPreview event and then check for 'delete/backspace' key when the current text is at a certain length (i.e. the length of the text you want to always be present). That might work

I also first thought of this, but suppose if user appended some text then its lenght got increased, now he acts smart and jumps back , then he can delete as length is greater(as he adds some text)
Application is on order progress.
Where user has to update its order action/remarks?
I am fetching text from DB to textControl, and user have to update these fields.
So if user once entered some data and updated it, then next time he can only append new data, can't modify previous data.
Any help appreciated....?

I knew it would have a flaw somewhere lol
what about on KeyPreview do some check using the caret position of the text box?
So keep the backspace/delete check and also add - if caret < fixed length then don't allow key press to go through

an example would be greatful.
or else i have to run hit and try method on my own

Perhaps if you build on musefan's idea but use the Tag property to store the length of the Text when the TextBox has been initialized (i.e. the "uneditable" text has been assigned to it)..? Then you always know the initial length and you can prevent it from being modified.
However, I think a better solution would be to split the UI to reflect that there's a read-only part and the user may add to this. This would make it easier to implement, and imho more logical for the end user as well.
If you do opt for a single TextBox control you may have to handle cut/copy/paste (if you select text and paste, you replace the selection) as well.

Manually.
See TextBox.OnChange event, but be aware that this is "odd" behaviour - not what users expect from a text box. Is there no better solution you can apply, such as moving the text to a label so the TextBox is empty?

This is one solution?
But moving whole text to a label then adding new text?
application like daily/weekly update on a task.
so text is goes on increasing?
also there are 3-4 fields where user has to add its progress,
and moving each on a seprate labe, makes things somewhat unpleasent?
can't there be any better way.....?
just user can't modify previous data?
any help appreciated....

Ok, so what it is is an update of a to-do-list or similar, with the user inputing new progress?
In which case, yes it will keep increasing - what you need to do is treat each new progress update as a new record and display it in - for example - a grid control. Or better a DataGrid if you store the updates in a database, which would make sense.

Try this in TextBox Keypress event
if(textbox1.text.lenght > 0)
{
if(e.KeyChar == "backspace","Delete","shift","Home","End"
{
e.Handled = true;
}
}

I think that is not sufficient, the user could still use the mouse to select some text, then type new text replacing the selection.

how about each 'update' is a new entry in the database. then you use a control such as a datagridview (or make a custom one) that displays each entry along with the time and date that it was made. Much better solution

I would avoid having both old data that should not be changed, and new data, that the user wants to add and edit, in a single control.
Maybe have a read-only TextBox showing what is already processed, and a smaller TextBox allowing the entry (with editing) of new data plus a "Enter" button (or act on ENTER key).
And as always, I don't like Textboxes for large amounts of data, so I would prefer a ListBox or DataGridView for old data, and a Textbox (or whatever suits best) for new data.

Hello,
How can i access public variables in a WebService..using the object that i create in the WinApp?
Is posible to call method at a WebService by sending its paramters by refrence..?
Thanks
|
|
|
|
|
Well I would say no. Sending by reference will not work, because both 'apps' (winapp and webservice) reside in different memory spaces. The pointer (reference) to a position in memory will be uselesse to the other part...

Hi,
You can't access fields in a web service. It would be possible to change the state of the service by calling a web method and then have the service change it's own state in response to it, but in general web services should be stateless so it's basically a bad idea.
It is not possible to send parameters by reference to a web service.
You might want to look into remoting as it seems the things you want to do are the sort of things a web service isn't right for. Web services have one primary advantage over other services: They are more interoperable - it is possible to build clients for the service using many different tools and this in turn means it can be used by a Symbian cellphone or an iPhone or a Windows/Linux/other-based computer.
It is also possible, with WCF, to build a service class and expose it through remoting AND as a web service (as well as other endpoint types). You may want to learn a bit more about the technologies before you go ahead and design the solution to whatever problem you're trying to solve.
