What's the diffenrence between these two assemblies?

I encountered with an error when i tried to move a VS 2005 Shared Add-in project from one computer to another. The original machine has got VS 2005 Team Suite on it while the second one has got VS 2005 Professional Edition. During the original development on the first computer, I referred to an assembly "Microsoft.Office.Interop.Outlook"(which is added via: Add references -> COM -> Microsoft Outlook Object Library 11.0). However, the second machine cannot find the assembly and I have to manully change it to "Interop.Outlook"(which is also added via: Add references -> COM -> Microsoft Outlook Object Library 11.0). And I have to do some modification to the codes in order for the project to build successfully.

Why did the problem occur? What's the reason behind it?

Trapeze-shaped form...

Hi everybody,I'm new here and I have a question... I'd like to create a form which would simulate a perspective view, so my form will have to have a trapeze shape. I don't want to use Region(myShape) because that will clip my form and I want to have the entire form.
Thanks in advance for any suggestions.

U have to create a image of the same shape as u want the form to be.(set some color in the image region e.g. black)
then set this image as the background image of the form.
and then set the transparency key of the form to the image's color i.e. Black

Hope that works for u.

Thanks & Regards,

Assuming that you want to create a help file from your code, you need to document your methods with the XML document markup, e.g:

/// <summary><br />
/// Method to do something interesting.<br />
/// </summary><br />
/// <param name="interesting">An interesting parameter.</param><br />
public void DoSomethingInteresting()<br />
{<br />
}

You also need to set your project to produce the XML markup in the using /doc. To do this, select the project properties then Build and switch the configuration to All Configurations. Assuming that you are using VS2005, you need to check the XML documentation file checkbox and enter the name of the project in the corresponding textbox.

Next, do a build to produce the XML documentation.

Finally, you need to use something like Sandcastle to convert the XML to CHM. I would suggest that you do a search for Sandcastle on CP to find articles on using it.

Marshalling - Structure inside Structure

I need helpwith marshaling.
I have a c# application talking to c++ dll.
I am using a dllimport and in one of the API parameter,
I need to use a struct inside struct. I pass the referance of the struct and struct gets populated by dll.

[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]
public struct Record
{
[MarshalAs(UnmanagedType.ByValArray, SizeConst = 16)]
public byte[] array1;
};

[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]
public struct List
{
public uint numberOfRecords;
[MarshalAs(UnmanagedType.ByValArray, SizeConst = 32)]
public Record[] Records;
};

Is this ok ? will it have 32 x size of record or does the marshalling say the list structure has total 32 bytes ??
please help.

do a foreach and compare the rows/columns of the grids. you can also do this with the dataset or datatable before you fill it instead.

hope that helps some.

Isuses with timers + fast intervals

Hi, I have a question about the Windows Forms Timer class.

Suppose that the timer's interval is set at say 10ms and the work it does in each tick takes longer than 10ms to complete.

Is each tick executed on a separate thread? If not, then what happens?

Im guessing the next Tick will be delayed. Good question.. You can experiment with two timers and two counters .. the one with the lower count would be the delayed function.

So the tick executes again if it cannot complete it's work before the next tick is called?

Hi,

the timer event occurs after 10ms even if the first execution of event is yet to complete.

what u can do to cope this prob is set the timer enabled=false once its event execution starts so event doesnt fire again even if 10ms is over.
and when ur code execution is complete u can set enabled=true again.

Something like this<br />
<br />
timer1_Tick()<br />
{<br />
timer1.enabled=false<br />
//do ur work here<br />
timer1.enabled=true<br />
}

hope this works...

No, all ticks on a System.Windows.Forms.Timer run on the UI thread.

bankai123 wrote:

Every timer tick runs as a result of a WM_TIMER message being processed by the message dispatcher. Windows doesn't post the WM_TIMER message to the message queue if they are any pending messages (including WM_TIMER) in the queue. This prevents the scenario you described (a tick firing even when processing for the previous tick is executing). Note that any message in the message queue will prevent the timer from ticking, so for example, if your UI button click handler takes one second to execute, then you won't get timer ticks for that one second.

Also, note that no queuing of ticks happens, so you won't get ticks one after the other corresponding to the period when no timer ticks executed. In the above example, you won't get timer ticks corresponding to that one second period even after your button handler has completed execution.

Hope this helps.

No, but I think "System.Timers.Timer" does.
There you have to use the "Elapsed" event.

Thanks for all the info, it has been helpful.

I've decided to use the System.Timers.Timer class instead, with a interval of 20ms for processing some information. I tried disabling the timer once i entered the event handler and re-enabling it after all the work is done. ( to avoid re-entrance)

However it didn't seem to work for me, It seemed to call the first elapsed event once, and doesn't seem to occur again.

I gotta debug more, not really sure where the problem lies at the moment.

C# 2.0 ASP.NET Postback & ObjectDataSource

kselman6-Nov-06 17:30

6-Nov-06 17:30

I think this is an easy question..

I have a DataList displaying data from a ObjectDataSource and an input form that inserts data into the same table. Upon postback the DataList is showing the data prior to the postback. How do I refill the data on postback?

Id post some code but filling of dataset and databind is "magic".. here is the code Im using in the ButtonClick function:

NewsDataSetTableAdapters.CommentsTableAdapter commentsTable = new NewsDataSetTableAdapters.CommentsTableAdapter();<br />
        commentsTable.Insert(newsID, subjectTextBox.Text, commentTextBox.Text, ipAddress, DateTime.Now, emailTextBox.Text);

Re: C# 2.0 ASP.NET Postback & ObjectDataSource

It's pretty common to put the code to fill the data list in the Page_Load routine, and to place it inside an if (!IsPostBack) test since normally you only need to populate the control once, when the page loads. However, if you happen to have your population code inside this test for your particular situation, it wouldn't repopulate the control on the postback because it's explicitly told not to.

Don't know if this is how you have your code structured, but if it is, your fix may be as simple as moving the code outside the test so that it executes on every invocation of Page_Load, postback or not.

Hope this helps...

using WinForms control from another thread

peterchen6-Nov-06 13:09

6-Nov-06 13:09

I am trying to use a WinForms control from another thread. Unfortunately, I can't use Control.Invoke directly, because the control calling code is hidden:

A Worker Thread modifies a DATA class. This fires an Event caught by a CONTROLLER class, which in turn tries to update a TreeView.

This doesn't work because the Node update is called from a worker thread.

(I am trying to feed my Generic Tree[^] in a worker thread)

Is there a way around it? Or do I have to change all calls in the controller to Invokes to delegates? OMG | :OMG:
