Problems Setting up a Form that Emails Tasks [modified]

Hi people,

I was wondering if somebody could point me (a C# novice)in the right direction with a problem I have?!

At work,the people above have told me I cannot install any C# software on my PC. Mad | :mad:

However, I want to create a form that allows a user to send an email to somebody chosen from a drop-down list. The email should contain all the info from the fields on the form. (We have Microsoft Outlook 2000 at work).

The data from each record would be stored in a Microsoft Access 2000 database.

(1)How would I go about creating a class that sends emails?
(2)How could I ensure the application is stand-alone and could interact with Outlook 2000, without me breaching any company regulations about installing software at work?

Many thanks in advance. Big Grin | :-D

So why are you asking here ?

There's one built into C#, but as you're not allowed to use it, what language do you hope to use instead ?

Jag77 wrote:

You can't - it will require the .NET framework, no matter what, if it's C# or VB.NET.

Jag77 wrote:

There are MAPI classes for C# on the web.

If you're not allowed to install anything written in C#, you need C++ ( which is going to be a lot harder ). IF you're not allowed to install ANYTHING, no matter what the language ( which your last statement implies ), then you're out of luck, unless you can script something within outlook or Access itself. They can't possibly complain that you're running scripts in a program already installed, right ?

XML Serialize / Deserialize generic dictionary holding various generic types

Hi,

I'm kind of stuck with an serializing / deserializing problem using a generic dictionary holding references to various generic types. It goes as follows:

<br />
<br />
class MyBase : IXmlSerializable<br />
{<br />
 // whatever<br />
}<br />
<br />
class MyGeneric<ValueType> : MyBase, IXmlSerializable<br />
{<br />
   MyGeneric(Valuetype tVal)<br />
   {<br />
     val = tVal;<br />
   }<br />
   ValueType val;<br />
}<br />
<br />
class Program<br />
{<br />
   dictionary<string, MyBase> m_Dic = new dictionary<string,MyBase>();<br />
<br />
   void FillDictionary()<br />
   {<br />
      dictionary.Add("Key1", new MyGeneric<int>(10));<br />
      dictionary.Add("Key1", new MyGeneric<string>("StringValue"));<br />
      dictionary.Add("Key1", new MyGeneric<double>(3.1415));<br />
   }<br />
}<br />

Ok, I hope you can see the idea behind it. It's mainly thought to hold a variety of different types whithout specifying a parameter enum which selects the appropiate value via a huge switch statement on lots of overloads to the value Get/Set property.

While I'm able to serialize the dictionary without a problem to an XML file, I'm stuck deserializing it.

The problem: how can I can generate a generic from a textinformation like

<mygenericofint32> or MyApp.MyGeneric`1[System.String] ?

The first classification is generated by the .Net serializer and the second is generated from typeof(...) .

Any ideas are very appreciated.

Thanks,
Florian

For the interested ones, I found a solution:

<br />
Type   t = Type.GetType(typestring);<br />
object o = Activator.CreateInstance(t); <br />

This works, if you serialize the type on saving with GetType().ToString().

Hello!
I think it's a simple question, but i don't know where to start looking for the answer... I have a program which launches several processes. But, i don't want the program to launch a process if the application (the one the process is supposed to launch) is already running. My problem is checking whether the process must be launched or not. I thought searching the Task Manager, but i have no idea on how to get there.
Thanks a lot! Big Grin | :-D

I've never worked with it before, but doesn't it have a Right click event?? If it has you can handle the event and check the MousePosition property relative to your control's location.

It's not approperiate to ask for how the answer is posted this way. Maybe you declare that code snippets are preferable, but almost no one will post you "The code"!!

Now, to your issue. There many approaches to solve it. One is to make a column at the begining of the grid. You may cal it "Order". Now make that column invisible and store the order you want the columns to appear with in these cells. Sort the Grid according to that column.

When the user clicks up, swap the order value of the selected row with the one above and resort. When the user clicks down vice versa.

Before changing the values, check if order = 0, or order = MaxValue. If so, return without doing anything.

Crystal Reports and filling dataset/datatable

Hi,

using VS2005;

I have successfully setup Crystal Reports but only if I create a new oledbconnection using the Crystal Reports Database selector.

When I select a table in the Database Selector from an available Project Data -> ADO.Net DataSets -> dataset -> table I can chose the columns etc BUT when I run the program the report only shows the column names and not the actual data.

I presume I need to load the data into the reportviewer but I can't figure out how and nor can I find any help here or on the net.

startup times woes....

Hi All!

I try to understand and improve my application cold start.

I already load as little as possible in the Main().

Now I have a test which gives strange results, and I try to understand what it means.

test 1:
====
I reboot, launch a small .NET executable, which takes 7 seconds, and launch my application, which takes 30 seconds.

test 2:
====
I reboot, launch my application, which takes 70 seconds.

Now this doesn't add-up, why?
Any idea what's going on?

I'm thinking to write a small "QuickStart" application which "initialize" everything. How should it work?

That's probably because most of the .NET framework runtime code was loaded in the cache when you launched the first .NET application. That still doesn't explain the 40 second drop though.

OTOH, 70 seconds to launch an application OMG | :OMG:

? What does your application do to take such a long time to startup?

70 seconds !! OMG | :OMG:

.

Anyway, I had the same problem with loading times.
What I did notice is that I performed a little bit too much tests, which seem to take a lot of time. (try/catch blocks, etc) That can help maybe (although it is important that the app doesn't crash.)

The only thing I did then, is suspend the layouts until after loading and loading as little as possible. Add an NGen compilation and that's about it, about what you can do in my knowledge.

What I also did is setting the thread priority to above normal. I figured that Higher priority processes get more processor time and thus run more quickly, but I should take care with this method...

On what cpu do you run the application?
I'm thinking that (especially .NET 2.0) needs a lot of memory to run quickly.

I've found a living worth working for, but I haven't found work worth living for.

uh.. intel something IIRC. 32 bits, .NET2, 1GB of RAM.
IT tooks a long while to load "simple classes" (well the most complicated does refer to a lot of other types but NOT that many!)

I suspect that one of my problem is an auto-generated ManagedC++ wrapper around some ObjectiveC API. The top level object class has a few hundreds methods! and each class is very big and there are quite a few object!

But the fact is, I just use a few of them...
