confusion over parsing data through layers

21-Feb-07 22:18

>>I have to apply css to file Upload control of ASP.NET 2.0.I need apply css to textbox and the button.

it can't be done with a trick..

Trick #1. (IE)
1. Set display style of "input file" to "none"
2. Add one button.
3. Write javascript function ("fileId.click();") in button click.
[Note: it works only in IE.]

Trick #2. (Cross-browsers)
1. Set transparency of "input file" to 0
2. Place one button (btnFileBrowse) above the button of "input file" [Make sure the z-order of "input file" is higher than "btnFileBrowse"]

Please check this article.
Styling an input type="file"

Hi,
Can someone explain the following to me. If I set a value in my Business layer, I am able to access it from another page?

<br />
'Code behind page<br />
'Import the BLL layer<br />
Import MyApp.MyBLL<br />
<br />
'Method to Set the value<br />
MyBLL.SetPermission(1)<br />
'Method to Retrieve the value<br />
Dim intPermissionLevel = MyBLL.GetPermission()<br />
<br />
'Business layer<br />
<br />
        'The value to be kept<br />
        Public Shared intPermissionLevel As Integer<br />
<br />
        'Go find the user Level<br />
        Public Shared Function GetPermission() As Integer<br />
            'Go find the user Level<br />
            Return intPermissionLevel<br />
        End Function<br />
<br />
	  'Go Set the user Level<br />
        Public Shared Function SetPermission(ByVal intSetPermissionLevel As Integer) As Integer<br />
            'Go Set the user Level<br />
            intPermissionLevel = intSetPermissionLevel<br />
        End Function<br />
<br />

I am able to get the value set in "intPermissionLevel", from another page. I set it in say page1.aspx, and then I can get the value again, from page2.aspx

Is this because the value is shared - and is this a good method? I do not quite understand this....

>>Is this because the value is shared
Ya.

>>is this a good method?
It depend on your system and what you wanna do with this member.

If you set the method/property as shared then you don't need to create an instance of object in every pages. so, it has less memory allocation. but you hav to take care of concurrency issue. (what if multiple users are accessing your page at the same time.)

I am getting an error 'No default printer' when I tried to print a report.
Some articles suggested to set the Username as system in processModel in machine.config. I did the same but no improvement, getting the same error.

Any one help me out here.

Thanks.

Are you able to print something manually from your machine? Eg: type something in notepad. And Click "Print".

For me, there is nothing required to update in machine.config.

>>I am using network printer as my default printer.
ya.i'm using network printer only .. it's working fine for me.

i think, ASP.NET doesn't have a permission to access this printer. so, you should try to impersonate with your user id.

IIS,
- Go To-> IIS -> Properties -> Directory Security ->
- Uncheck "Anonymous access"

And,
In Web.Config,

<identity impersonate="true"/>

<authorization>
    <deny  users="?"/>
    <allow users="*" />
</authorization>

Hope, it would help.

SFR problem

Imran Khan Pathan21-Feb-07 18:42

21-Feb-07 18:42

Hi Friends

I use SFR sensor in my web application using asp.net with c#.
When I click on button to initialize SFR I got Error.

bool returnvalue = sfr.Initialize();

Error is:- A call to PInvoke function 'Suprema!Suprema.SFR300::SF_SetSensitivity' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.

Plz give me right solution

Thanks in advance

Hi,

I have a webform and in that for the data is represented in a table such as:
table, tr and thereby three td's. Now there are textboxes in the first column as well as in the last column, however on clicking a button like 'clear' the textboxes content in column 3 should be cleared.

Tried using the foreach loop along with table, tablerow, tablecell but throws an error!!!

HI Gautham.

Try this code

foreach (System.Web.UI.HtmlControls.HtmlTableRow tr in tbl.Rows)<br />
            foreach (System.Web.UI.HtmlControls.HtmlTableCell tc in tr.Cells)<br />
                foreach (Control txt in tc.Controls)<br />
                    if (txt is TextBox)<br />
                        ((TextBox)txt).Text = string.Empty;

//tbl is table id

Which error?

gauthee21-Feb-07 19:52

21-Feb-07 19:52

foreach statement cannot operate on variables of type 'System.Web.UI.HtmlControls.HtmlTableRow' because 'System.Web.UI.HtmlControls.HtmlTableRow' does not contain a definition for 'GetEnumerator', or it is inaccessible

hi
If you know the ID of the HtmlTable where the textboxes are available you can do it as

<br />
<br />
HtmlForm form = (HtmlForm)Page.FindControl("Form1");<br />
		//	foreach(HtmlTable tbl in form.Controls)<br />
			HtmlTable tbl = (HtmlTable)form.FindControl("Table2");<br />
<br />
				foreach(HtmlTableRow row in tbl.Rows)<br />
{<br />
					foreach(HtmlTableCell cell in row.Cells)<br />
{<br />
						foreach(Control ctrl in cell.Controls)<br />
{<br />
							if(ctrl is TextBox)<br />
{<br />
								((TextBox)ctrl).Text = "";<br />
}<br />
}<br />
}<br />
}<br />
<br />

This will work..But you need to know the ID of the table which contains the Textbox controls to be cleared Smile | :)
