Actually, this may already be “second” or “third” hand …
He’s already promised someone that he’ll do it for $25.00; now he needs to find someone whole will do it for less than that … and so on; and so on.
(Just give them the source code to “anything”; they’ll never know the difference).

Hi Techies,
I am using .NET framework 4 chart controls in my system .I have a pie chart which represents the percentages of the user answering questions for each subject(e.g. history,maths etc).So,when the user answers few questions and then views the pie chart, it will show how many answers are correctly answered in each subject. I need to show the percentage of wrong answers in a subject within the pie slice showing the correct percentage (e.g: user answers 5% questions correctly, and 1 % wrong which has to be showed in a different colour ). So,basically I need to show a shaded region in a different colour within a pie slice which has its own colour which is set. E.g: In a blue region,I need to show a part of it as red.Is there any way this could be done??
It would be really helpful if you could give me some ideas on how to do this.
Thanks a lot for the help.

Dear Sirs,
I've looked and looked and can't seem to come up with the perfect solution. So, since CodeProject is perfect, this will cure my problem.
I'm getting System.String datetimes from a server (Microsoft CRM if you care). They're in SQL format ("2010-07-23T17:14:40-04:00"). I want to read that in as a .net System.DateTime type with the timezone information preserved, then convert it to local time. This process happens in various timezones, and I'm having trouble staying in synch. Basically, I get lots of CRM records from CRM server (which seems to stamp all the timezones with this Brazilian time (-4)), and I want to write down in my config file the latest one I saw (so I don't go back and pick up values that I already have). I would like to write it down in local time, though. Here's a distillation
I want to take the string "2010-07-23T17:14:40-04:00" and, run some code
System.Datetime Get_Local_DT(string val);
that will return "2010-07-23 15:14:40" in Central time (-6) and "2010-07-23 16:14:40" in Eastern Time (-5). Let me know what you think.

Hi,
I wanna know if is possible to put a iframe in masterpage file and the contentplaceholder inside the iframe.
Thanks.

This has nothing to do with C#. You'll want to ask this in the ASP.NET Forum[^].

Yes its possible, you could try that instead of spending time in writing question.

Hi all,
I'm developing a custom WebPart written in C# for MS Project EPM 2007 (Sharepoint 2007 engine), using Visual studio 2008, VseWss 1.3 and the .Net framework 3.5.
I also installed the ASPAJAXExtSetup.msi file and added the AjaxToolKit.dll binary into my project.
My Webpart display a simple DateTime.Now (among others). I wish to use an updatePanel and a Timer to refresh my string every second but unfortunately it doesn't work...
Here is my code:
protected override void CreateChildControls()
{
base.CreateChildControls();
try
{
if (ScriptManager.GetCurrent(this.Page) == null)
{
this.Controls.Add(new ScriptManager()
{
EnablePartialRendering = true
});
}
UpdatePanel updatePanel = new UpdatePanel();
updatePanel.UpdateMode = UpdatePanelUpdateMode.Always;
this.Controls.Add(updatePanel);
lblTimer = new Label();
lblTimer.Text = DateTime.Now.ToString();
updatePanel.ContentTemplateContainer.Controls.Add(lblTimer);
Timer timer = new Timer();
timer.Enabled = true;
timer.Interval = 2000;
timer.Tick += new EventHandler<EventArgs>(t_Tick);
}
catch (Exception ex2)
{
Literal ex2b = new Literal();
ex2b.Text = ex2.ToString();
this.Controls.Add(ex2b);
}
}
protected void t_Tick(object sender, EventArgs e)
{
lblTimer.Text = DateTime.Now.ToLongTimeString();
}
What is the problem?
Thanks in advance

|

I'm not sure it is wrong the way it is, however I tend to set all timer parameters before enabling/starting it.

First, this should have been in the SHAREPOINT forum.
Second, you have to do better than "it doesn't work". What doesn't work? What is happening?
Are you sure the required entries for ajax have been made to the web.config?

Nothing happens. My string stays fixed.
Are you sure the required entries for ajax have been made to the web.config?
Yes, I am.

Hi,
I've followed the following post ( http://blogs.msdn.com/b/sharepoint/archive/2007/03/02/integrating-asp-net-ajax-with-sharepoint.aspx[^]
but I have a problem for adding a ScriptManager into SharePoint MasterPage.
There is no "<WebPartPages:SPWebPartManager id="m" runat="Server" />" tag in my default.master file so i've added the script manager (<asp:ScriptManager runat="server" ID="ScriptManager1"></asp:ScriptManager> ) somewhere else in the file but when I try to upload the file, I get an error: "unknown server tag 'asp:ScriptManager'" and in my webpart page (with a try/catch), i get the following: "System.InvalidOperationException: The control with ID 'updatePanel1' requires a ScripManager on the page..."
How to solve the problem?
Thanks in advance

Impossible
crosslink06 wrote: requires a ScripManager on the page..."
Quite obviously the script manager must comee BEFORE the control that is trying to use it. That's why script manage is placed at the top of the page.

Here is my default.master file:

Why are you wasting space and time by posintg this? No one asked for it and the time you wasted to do so could have been spent determining where this crap came from, it is not the default master page for MOSS or WSS
I know the language. I've read a book. - _Madmatt

OK - Furthermore, it was not the correct master page, sorry about that.
I've added the AJAX tool kit .dll, edited the web.config and the the correct default.master files, then resetted IIS, built and deployed my solution.
Now, I get an error when I do a postback from my webpart. In addition, even if I modify and deploy the solution, nothing happens, the webpart seems to be blocked...
Thanks for your help

Indeed, with a Timer it's working but during a post back, I get a javascript error:
"Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are..."
That why I tryed to follow your trick: http://msdn.microsoft.com/en-us/library/ff650218.aspx[^]
For that, I downloaded the following http://www.microsoft.com/downloads/details.aspx?FamilyId=91f3c22c-8be7-4721-9449-84f699337d55&displaylang=en[^]
Then deployed the solution containing the AjaxSupport.dll into my server and add the reference into my web part project.
Then, I added the following within my default.master file
<%@ Register
Assembly="Microsoft.Practices.SPG.AJAXSupport, Version=1.0.0.0, Culture=neutral, PublicKeyToken=8768CCAE1C3C9EB2"
TagPrefix="spg"
Namespace="Microsoft.Practices.SPG.AJAXSupport.Controls" %>
<spg:SafeScriptManager ID="SafeScriptManager"
runat="server"
EnableUpdatePanelSupport = "True"
/>
Then, in my web.config, I added a safecontrol tag and resetted IIS:
<SafeControl Assembly="Microsoft.Practices.SPG.AJAXSupport, version=1.0.0.0, Culture=neutral, PublicKeyToken=87###########", Namespace="Microsoft.Practices.SPG.AJAXSupport", typeName="*", Safe="True" />
Now, I'm getting an error by uploading my default.master file:
"The Control type 'Microsoft.Practixes.SPG.AJAXSupport.Controls.SafeScriptManager' is not allowed on this page. The type is not registeres as safe".
Need some help, please.
Thanks

I've found! The problem didn't come from the environment but from my code.
I tried to set visible a textbox which didn't exist yet.

Hi,
I have a DataTable that is being generated during runtime with values from the memeory. Now my question is,is there a way you can run a sql query against the data in the datatable so that it can return data in a specifik format?
In my datatable there is for example three columns called A,B,C and I want to do someting to retrieve that data with the column names Name,Surname,Age instead of A,B,C for example. Like giving an alias to the column names when retrieving the data from the datatable.
Any Help is greatly appreciated.

|
|
|

You should be able to use DataTable.Select()[^] to query your DataTable.
As for your column names, give them whatever name you like when you create your DataTable, see here[^]

I have a desktop based application. Now I want that when my application installed then only administrator the system can have access to the event viewer.Apart from admin, other users cannot access the 'eventvwr.msc' file.
I know the manual method that how to restrict the access to the event viewer.
Task : Enable Event Viewer Permissions
Enabling event viewer user permissions restricts access to the event viewer log files. Once these permissions are set, only administrators will have access to the event viewer logs.
1. Browse to the c:/windows/system32 directory
2. Locate the file eventvwr.msc
3. Right click on the file and select properties
4. From the properties window select the security tab
5. Highlight and remove all entries except the administrators group/user
6. Click apply and ok.

hello
I need to provide facility for Matlab to do bulk insert to SQL. Matlab provides ways to load .NET assembly and call .NET methods:
Assembly reference: http://www.mathworks.com/access/helpdesk/help/techdoc/ref/net.addassembly.html
Method calls: http://www.mathworks.com/access/helpdesk/help/techdoc/matlab_external/brpb58s-1.html#brpca5n-1
However, we can't pass "Cell Array":
Example:
<br />
% 2 Dimensional array of numbers<br />
a=[1 2 3; 3 4 5; 6 7 8]<br />
aa=[1.1 2.2 3.3; 4.4 5.5 6.6; 7.7 8.8 9.9]<br />
% Single dimension string array (2D not permitted)<br />
b={'aaa0'; 'bbb0'; 'ccc0'}<br />
bb={'aaa0','aaa1'; 'bbb0', 'bbb1'; 'ccc0', 'ccc1'}<br />
<br />
c={'20100701' 1.11 2.22; '20100702' 3.33 4.44; '20100703' 5.55 6.66;}<br />
<br />
"c" above is cellarray
Now, my only option is to wrap bulk insert logic in ATL COM server, and call from Matlab as such:
dbServer = actxserver('MyDBComServer');
The first article below shows how to build a simple ATL server in C++ but:
PROBLEM 1: sample shows only passing simple type such as string/BSTR - I need to pass a Matlab CellArray across (For this problem... I don't have much clue how CellArray is represented in memory as thereby passed across Matlab/COM/.NET borders)
PROBLEM 2: I don't have access to .NET System.Data.SqlClient.SqlBulkCopy (For this problem can I packaged ATL done by C#? From Visual Studio 2008 \ New Project, I can find "ATL Projects" only under VC++. Is my option a COM server without ATL as indicated in Third Reference below? I am inheriting an old VB.NET COM project but having problem getting it registered, but it must be possible)
PROBLEM 3: Windows 2003 64 bit - any deadend you know?

Good Morning all,
Currently I try to accomplish to load a DLL (filename and path) as an assembly to be available to all classes in my project.
This is because one of our third party classes makes a call to an unreferenced dll and therefore fails.
I already tried different things:
- loading the assembly into the AppDomain.CurrentDomain
- instanciating objects of the required type via reflection
- I tried different locations for doing the above mentioned things (Startproject, directly before the error occurs, etc)
All solutions loaded the assemblies, but the type seems inaccessible to the third party class.
In VisualStudio 2010 in the output window I can see the line saying that the dll is loaded.
Funny (yeah, not really funny, quire obvious) is that when I copy the dll into the executing directory or reference it via the Project References everything works fine. Unfortunately this is not a solution, because we use MEF to import such classes (third party) into our Application.
I thought about copying the dll to the application folder because thanks to MEF I can get a handle on every DLL necessary... but that would be quite ugly, wouldn't it?
I guess I just forget about something...but it doesn't pop into my mind..
Any help is kindly appreciated,
best regards
Andy
