I wanted to save bitmap file as vector image with emf extention.
bitmap.save(filepath, ImageFormate.Emf);
While running the program above line throws ArguementNull exception that "encoder value is null".
For getting encoder information :
ImageCodecInfo[] list = ImageCodecInfo.GetImageEncoder();
this list containing 5 element : BMP,JPEG, GIF, TIFF, PNG
These are the built -in- image codec.
But codec related to .emf is not there. Might be thats why exception is throwing.
Am I need to install codec for emf or there is any other solution?
Thanks alot....

As the title says System.IO.Ports.SerialPort.Open() is catching TimeoutException popping a MessageBox and continuing to try to connect until I call close. I would prefer to catch the exception myself. Is there a setting somewhere in my VS8 that controls this? I don't see anything in the docs that mention it.
TIA,
Greg.

Are you sure that is not in your code? According to the documentation[^] the Open() method neither throws nor catches TimeoutException.txtspeak is the realm of 9 year old children, not developers. Christian Graus

Your right. Mea culpa. I was expecting open to fail but it isn't it's the first read that is failing. Thanks.

Another member when using code in one of my articles came across a peculiarity that I'm trying to resolve.
It seems that whenever the DataSource of a DataGridView is changed, if the mouse is over the Control, a WM_MOUSEMOVE (0x0200) message is generated 
Is there any reason why this would be the case, and any idea of a workaround as the component does something on that message so this situation is causing undesired and unexpected behaviour!?
[Edit] The only quick workaround I can think of is to store and check against the previous lParam of this message to see if the mouse has actually moved - yuk! [/Edit]
[Edit2] The workaround using lParam is here[^] if anyone else comes across this. [/Edit2]

Hi Guys!
I am in a bit of a Dilemma here and need some help. I have a table that has a row and three columns which are showed to the user after the page loads. There is a button which calls a code behind function to add a new row. The first time the user clicks, the row is added properly, no problem. The second time however, the row is not added but the previous row that was added is updated with the new id/name etc. Also the second time, the drop down menu gives an error which is quiet ridiculous, something to do with accessing innerHtml of the drop down menu when I am not even asking the compiler to assign anything of that sort. Please have a look and let me know where the problem is which my brain cells are failing to recognise.
Note: I have tried all the different methods to add the row for example table.Rows.Insert(index,htmlRow) etc.
Thanks is Advance.
Below id my code for reference:

Go back and edit your post. There's some tag in it that's screwing up the formatting of the entire forum!

Hi Dave!
Please let me know if this edit solved the problem, else I can delete the post. Sorry for any inconvenience caused

You have broken Forum, if you can edid, edid part that uses <>. I recomend when you pasting use option: "Encode "<" (and other HTML) characters when pasting".
For the actual code, please use PRE tags, so that is more readable

Should it be the PostBack of iBtnAddRow that generates all the code again! Try saving the table in a Session or a ViewState!  and after every postback return it back!
like
protected void iBtnAddRow_Click(object sender, ImageClickEventArgs e)
{
Session["YourTable"] = tblLoanTypes;
}
private void Page_Load(
{
tbl_LoanTypes = (HtmlTable)Session["YourTable"];
}

Thanks for the reply mate! I'll give it a try and see how it goes though I am sure that it might not be a good idea saving the table in the session as this is a high traffic site and people can have more than 10 rows in their table. So the table times the number of users may make the site perform slow. Nonetheless, I will carry out an SVT and see how it goes.
Regards.

I have a customized ComboBox and a class with many properties. I am putting one of my ComboBoxes on my MainForm for each property in my class. When it’s time to “run” my application I need to transfer a value from each ComboBox into a different property in my class.
Ex: I have 5 MyCB : ComboBox and MyClass with 5 properties. When I start my processing I need to take a value from each ComboBox and put it into a different Property.
MyClass.PropA = MyCBa.MyValue;
MyClass.PropB = MyCBb.MyValue;
MyClass.PropC = MyCBc.MyValue;
…ect…
This doesn’t “feel” like the best way to do this. I came to this feeling when I needed to do a similar process for 20 items and was just cutting and pasting code and changing a letter.
My question is: Is there a more OO way of doing this, or a “best practice” method/pattern for this type of mapping? I would love to hear all ideas and suggestions.
Thank you all for your time!

You could create a global static binder class that contains both set of properties (the ones for class A, and the ones for class B). In the Setter method for both sets of properties, just set the other set of properties with the specified value. Then, when you Get the property (no matter which version), you'll always get the same value for the given property.
I think that would be one way...
Of course, you could just derive class b from class a (a from b, whichever is applicable) and then you'd get to use all those properties without having to do anything special..45 ACP - because shooting twice is just silly

Of course this is not the "preferred" MS way because it does not use data binding. Also, it does violate the principle of Data Hiding so it isn't the best OO method either but it is easy.
public class MySpecialLittleComboBox : ComboBox{
private MyClass MyClass{
get;
set;
}
protected override void OnSelectedIndexChanged(EventArgs e) {
base.OnSelectedIndexChanged(e);
MyClass.SomeProperty = (Items)SelectedItem;
}
public MySpecialLittleComboBox(List<Item> items, MyClass myClass){
Items.Clear();
foreach (Item item in items) {
Items.Add(item);
}
MyClass = myClass;
if(Items.Count > 0)
SelectedIndex = 0;
}
}

Hello,
i am using visual C# express 2008. I SOMETIMES get the illegal cross thread operation in my invoke method when i try to run my project. I check the InvokeRequired property, invoke the same method and in the 'else' condition i create atemporary variable and assign it the text of my control. But on that line, in the 'else' statement, inside the Invoking method i sometimes get the exception. What could be the cause? How to get rid of it? It does not occur often, but it is still a bug...
TY

Try using BeginInvoke on your control instead.Me, I'm dishonest. And a dishonest man you can always trust to be dishonest.
Honestly. It's the honest ones you want to watch out for...
|
|
|
|
|
|
FYI, that would prevent a locking situation, but would not likely prevent a cross-thread exception. It would also change the flow of the program (i.e., the call would be asynchronous rather than blocking), which the OP may not want.
