Re: Please help me to set dataGrid Scrolling - ASP.NET Discussion Boards

Hello

I am using my.settings to create a application scope connection string.

The customer would like to change this if they want to connect to another database, and this should update the app.config file with the updated connection string.

My problem I have into the setting and create a connection string (easy). But I don't know and can't find out to update and save the new connection string.

My.Settings.cnnString = "This is example connection" 'Error read-only property

I am using vb.net 2005

Can anyone help,

Thanks in advance,

Steve

To access and modify web.config or app.config you need to use Xml Classes.

Hi steve
You can use web.Congig Connection for this Problem. If you get web.Config Connection string means it is very useful for future updation for connection.If you use the same Connection is whole project means . you dont want to change it for whole application. just you do the nessecary changes in we.config.In Web.Config you can access more than one database.

I got this code and it seem it would work. However, there is a problem with the code. I get a "Object reference not set to an instance of an object."

Here my code.

<br />
Dim config As Configuration.Configuration = Configuration.ConfigurationManager.OpenExeConfiguration(Configuration.ConfigurationUserLevel.None)<br />
        config.ConnectionStrings.ConnectionStrings("ServiceMasterConnectionString").ConnectionString = "This is new connection " 'Error - <br />
        config.Save()<br />

hi,

the basic concept behind menus in webbased project is to display and hide html elements. here is the simple code explaining this concept. u can format according to your need...

<HEAD>
<style type="text/css">

a.links:link { font-family : Arial; font-size : 12px; color : white; text-decoration : none; }
a.links:visited { font-family : Arial; font-size : 12px; color :white; text-decoration : none; }
a.links:hover { font-family : Arial; font-size : 12px; color : #FF9C03; text-decoration : none; }

td.menu{background:#4891C6}
table.menu {font-size:100%; position:absolute; visibility:hidden;cursor:hand }
</style>
<script type="text/javascript">
function showmenu(elmnt)
{
document.all(elmnt).style.visibility="visible"
}
function hidemenu(elmnt)
{
document.all(elmnt).style.visibility="hidden"
}
</script>
</HEAD>
<body topmargin="0" leftmargin="0" rightmargin="0">
<table width="100%">
<tr bgcolor="#4891c6">
<td style="cursor: hand" onclick="location.href='page1.aspx'" width="14%" onmouseover="showmenu('Mainmenu1')" onmouseout="hidemenu('Mainmenu1')">
<a class="links" HREF="page1.aspx">MainMenu1</a><br>
<table class="menu" id="Mainmenu1" width="100%">
<tr>
<td onclick="location.href='page1.aspx'" class="menu"><a class="links" HREF="page1.aspx">MenuItem</a></td>
</tr>
<tr>
<td onclick="location.href='page1.aspx'" class="menu"><a class="links" HREF="page1.aspx">MenuItem</a></td>
</tr>
<tr>
<td onclick="location.href='page1.aspx'" class="menu"><a class="links" HREF="page1.aspx">MenuItem</a></td>
</tr>
</table>
</td>
<td style="cursor: hand" onclick="location.href='page2.aspx'" width="14%" onmouseover="showmenu('Mainmenu2')" onmouseout="hidemenu('Mainmenu2')">
<a class="links" HREF="page2.aspx">MainMenu2</a><br>
<table class="menu" id="Mainmenu2" width="100%">
<tr>
<td onclick="location.href='page2.aspx'" class="menu"><a class="links" HREF="page2.aspx">MenuItem</a></td>
</tr>
<tr>
<td onclick="location.href='page2.aspx'" class="menu"><a class="links" HREF="page2.aspx">MenuItem</a></td>
</tr>
</table>
</td>
</tr>
</table>

Crystal report version for INVENTORY application. It gives us error to see the crystal reports which uses the crystalreportviewer component in aspx pages.e.g.FormInvSRFViewPrintingDetails.aspx which shows the error.

If we try to use our version /dlls it does not show the report and gives error when the application is running.

The component shows the version as 'Version=9.1.3300.0' and when Sameena asked Milind (Cybertech) about the version of Crystal reports used...he said he'd used version 7 for it. The framework which is used on server is different than our working version. and that is only framework which we cannot use for developement purpose.

If we make changes in the code and build the dll and put it on the server then it gives error when we try to print the reports.(the printing reports are mainly use the crystal reports dlls.)

So any changes done in the code anywhere in the project give us problem related to the report version as the crystal dlls has different version than it has on the server.

We got the crystal report version 8 from CG also ,which itself is giving error when installation takes place...SO it's of no use.

We are looking for the correct version of it which we haven't got yet.

So as of now we cannot proceed further on inventory module. Plz try to look in the matter from your side also .

Hi all,

I have some values in session like client id, client name. when I redirect from payment gateway to own site(e.g. thankyou page) I want to access all session variable. It works fine in IE but in other browser session value destroy. it works in local system problem is with online only.

Problem occures when I return back from payment gateway to my own web page. e.g.-

step 1. payment page(my website page)
step 2. paypal (payment gateway)
after successfull payment on payment gateway when we click "return to merchant" button..
step 3. thankyou page (my website page)
I want to use session variable "I created in payment page(my website page)"

I can use these session variable in IE but in case of firefox or opera I cannot get these variables.

If the modify.aspx is different from you datagrid.aspx then put all the data binding in the Page_load inside IsPostBack.

Dear Vijay.. Big Grin | :-D

Please check whethere the page post back is true or false .. in page_Load Event.. because if you put the post back is true in page load.. The values will not reflacted..

Hi friends, I need brief information about assemblies and example for that. Please Help Me. Thanks In advance for your help.

Hi,

U could check out some websites like:

hi daniel,

Thanks a lot.

I tried to create Assembly program.
I followed the steps in the site. But in Step3 i am getting error.

I dont what is this error because i am new to asp.net. Please tell me.

The Steps

Step 1 : Creating our sample component
Here is the code for the component. It just includes one method which returns a string.

imports system namespace BAJComponents public class Sample public function GetData() as string return "hello world" end function end class end namespace
Step 2 : Generate a key file
To generate the key file issue following command at command prompt.

sn -k sample.key
This will generate the key file in the same folder

Step 3 : Sign your component with the key
Now, wee will sign the assembly with the key file we just created.

vbc sampleGAC.vb /t:library /a.keyfile:sample.key
Step 4 : Host the signed assembly in Global Assembly Cache
We will use AL utility to place the assembly in Global Assembly Cache.

AL /i:sampleGAC.dll

The Error I am getting in step3:
Source file 'sampleGAC.cs' could not be found
S2007: Unrecognized option: '/a.keyfile:sample.key'

Thanks & Regards

Prya

wrong
~~vbc sampleGAC.vb /t:library /a.keyfile:sample.key~~

It should be
vbc /t:library sampleGAC.vb /keyfile:sample.key

wrong
~~AL /i:sampleGAC.dll~~

It should be
gacutil /i:sampleGAC.dll to place an assembly into GAC.

System.IO.Ports is not available in asp.net vb.net 1.1 ?

Is System.Web.Services.Description.PortCollection what you are looking for?
