Hi
I have placed objects Button and 12 objects Panel on an UpdatePanel.
When i click on a button, a panel appears (on the event OnClik, the precedent panel become invisible, and the new panel become visible)
Despite the object ScriptManager and UpdatePanel, when i click on the button, all the screen refresh. Is it normal ?
It has seemed to me that with Ajax, the screen does not refresh !
Thank you for advance

if the agenda is to hide and show panels then why are you using ajax and update panels along with server side code.
you can use simple javascript to acomplish this task.
and your page will be get refresh.....

Hi,
Ok but how can you do that ?
Can you show me an example of code ?
Thank you for advance
|
|
|
|
|
you have to set the conditional mode(properties) of update panel to conditional so only
update panel can be updated. entire page can not be updated.
|
|
|
|
|
Hi,
I have set the properties UpdateMode to Conditinal but all the screen refresh too
|
|
|
|
|
create a javascript function pass it panel name
use following code in it.
document.getElementById(panelid).style.display = "inline"; -> to show panel
document.getElementById(panelid).style.display = "none"; -> to hide.

Yes...it's very interesting but my knowledge are very limited so
please can you continue your explication ?
the button and panel lines describe in the aspx file are :
<asp:button id="Bn01" runat="server" text="Février" xmlns:asp="#unknown">
<asp:panel id="Panel1" runat="server" backcolor="Lime" height="125px" xmlns:asp="#unknown">
What do i place in the OnClick="..." ?
what will look like the javascript code ?
Thank you for advance
|
|
|
|
|
you have to use the update panel in place of panel as per your code
and set mode to conditional of each update panel.
so take the update panel instead panel.

Hi,
I am a new user of iTextSharp(Ver 4.1.2). I am using this dll with ASP.NET 2.0. I am able to convert a text file to PDF and also able to password protect it. Now I am trying to implement signing the converted PDF using a "security certificate"(a digital security file=x.509 V3 type).
I don't know where to start and how to proceed. Has any 1 done this before?? Please help me in getting the converted PDF signed with "security certificate". Sample code Or URL link would be much helpful.
Thanks,
DKDOTNET.

Hello,
my web-application must run with requireSSL="true" on the web-server. But within my local environment, I use requireSSL="false". Is there a way I can switch this on and off dynamically come deployment? "If (! System.Environemnt.MachinName.Equals("MyLocalMachine")) { ... ?
Hope to hear from you,
many thanks,

Hi,
I am trying to use TextReader and TextWriter to Read and Write some text files from business layer. But it is throwing permission error.
Any idea how to overcome this.
Any suggession to achieve this will do good for me.
Thanks.

Hi,
i would guess that the ASP.NET process (ASPNET or NETWORKSERVICE, depending on IIS version) has not the rights to access the files. If this is the problem you have to give access rights to this user.
Could you post the error message?
Regards
Sebastian

I think you are correct. He has to give the access right to that folder or need to change IIS Application Pool Identity of Local System.

I actually want to give file IO permission to a particular DLL only. i.e. my business layer Class Library. Any other dll im using in my project should not have access to read or write files on the server.

Its not the code that is executing that you grant permissions to, its the USER that has the permissions, so its not possible (unless you start playing with impersonation I guess?)

I don't mind which ever way i do. But this is the requirement because I can't trust all the Dlls I am using in my project.
I will be happy to do if it is possible. May be by any setting in web.config I Guess.

Why? They are surely under the control of YOUR application, they aren't suddenly going to start doing things by themselves - as long as your application is properly tested I can see no risk - unless its self mutating code, in which case its a virus.
Anurag Gandhi wrote: May be by any setting in web.config I Guess.
No, impersonation is something you would need to do in code just before calling your dll. I'm not sure you really understand what you are doing. A function in a DLL is called from YOUR application, usng (normally) the same credentials as the application. It is possible to change the credentials before the call by using impersonation, BUT this is something you need to be very careful of.
If all you are wantng to do is read/write to a specific folder grant access to THAT folder only, then your application cannot write to any ther location

There can be a huge discussion on "Trusting on dlls". Its a personal preference.
You can see only function input and output unless you decompile it.
When you call a function, internally, it may read your system information and send it to some website or webservice apart from giving the correct result. You may never know but can be done. Even proper testing may not solve all the trust issues.
I am not saying Dlls does it. But, according to me, not having security gives hackers a good chance to attack to your server.
About Impersonation, I will google it.
Well, my problem appears to be solved by changing a setting in web.config.

Granting access to that folder seems to be a good option.
Thanks Bob for all you valuable feedback.

It seems I was making an incorrect assumption. When you said it was a dll in yur business layer I assumed it to be a dll written by you (or someone in your company), I never thought about it being a 3rd party one.
Anurag Gandhi wrote: When you call a function, internally, it may read your system information and send it to some website or webservice apart from giving the correct result. You may never know but can be done. Even proper testing may not solve all the trust issues.
True enough, but your OP was about writing to a specific folder. It doesn't matter what context you run under, this type of thing could still happen, its all about knowing the source of your dll.
Anyway, hopefully you will resolve it. Personally, I rarely use dlls from unknown/untrusted sources. If its a library type function (such as convert to pdf) then I get it from a recognised source, otherwise I usually write my own.

I'm trying to a rather odd conversion: a set of wmv to FLVs transport streams. The command I'm using is:
Most of the time it works. However, some FLVs are encoded differently than others, and I sometimes get this error:

I have got stuck up with ASP.Net tree view.
Business requirement
There are parent type nodes called category (folders for example).
Child node can be category (folders) or factor (files for example) in business term. Factor cannot have child. In the sense a leaf node can be category or factor. The requirement is of different image on expand collapse of nodes for category and for leaf node which are factor they want third image, if lead node is a category then they want image that is same as expanded category.
Problem and scenario
I did some property settings to bring these images as per requirement. But the problem came in picture when I tried to add image through code for leaf nodes. The leaf node are getting indenting compared to their siblings. They are starting from other nodes text starting point ,that is the reason they are getting indented. I could not include NoExpandimageURL property for leaf node because my leaf nodes are of two types and have different images for each type. Is there any way to make this proper align?
Code written for tree view generation.
(Source file)
<asp:TreeView ID="tvwCategories" ExpandDepth="2" runat="server" CollapseImageUrl="../../_LAYOUTS/IMAGES/category.gif"
ExpandImageUrl="../../_LAYOUTS/IMAGES/CatCollap.gif" NodeIndent="15" Width="209px" BorderColor="Transparent" BorderStyle="None"
OnSelectedNodeChanged="tvwCategories_SelectedNodeChanged" NodeStyle-HorizontalPadding="5" NodeStyle-VerticalPadding="0">

Hi Friends,
The following code has been used in one of the asp page to fetch data from excel sheet and insert into table. Excel Driver part is used to do this. But however the excel sheet includes more than 130 rows. But when importing it just imports only 91 row and the remaining rows are not getting uploaded in the table. Please Please help.
ExcelDriver Part:
set objConn = Server.CreateObject("ADODB.Connection")
set rsExcel = Server.CreateObject("ADODB.RecordSet")
strName = "\Uploads\bicreports\" & strFileName
servername = server.mappath(strName)
' Create a connection string.
strConnectionString = "DBQ= " & servername & _
";DefaultDir=" & SERVER.MAPPATH("/bicreports/") & _
";Driver={Microsoft Excel Driver (*.xls)}" & _
";DriverId=22;FIL=excel 8.0" & _
";ImplicitCommitSync=Yes;MaxBufferSize=2048;MaxScanRows=8;PageTimeout=5" & _
";SafeTransactions=0;Threads=3;UserCommitSync=Yes;"
Is there anything wrong with above code attributes...which forces to read only 91 rows...
Its very urgent...Please help...
Thanks lot in advance.
