CCI3.Forms.frmEdit s = new CCI3.Forms.frmEdit();

above line in your code makes a new instance. i'm saying it again u need to get a already opened instance reference.

new keyword always make a new instance.

Internet download buffer problem

Well I guess a simple solution to the problem would be to declare a public event (say OnEditFormClosing) and when you create an instance of the Form2 (the Image Edit Form), register that event (Handler of the event) in Form1 (Original Form).
Now when you close Form2 (Edit Form), handle its 'Close Event' and from there Invoke the event (OnEditFormClosing), this will notify your Form1 that Form2 closed, as a result you can refresh the image in picture box may be by reloading or whatsoever procedure you adapt.

I downloaded a file from the Internet which had 3500 lines in the file. My program consistantly stops around 2400 lines. I assume it must be a buffer problem. How can I have my program automatically adjust to the buffer size needed.

Stream data = webClient.OpenRead(downloadAddress);
StreamReader reader = new StreamReader(data);
String line;

// Read and display each line from the file by segment
while ((line = reader.ReadLine()) != null)
{
etc.,
}

I appreciate any help,
Michael

Projects Don't work on Computers without VB

I have been trying to send my program as a gift to my sister, but when she tries to install the program it says that not all the files are their. I've copied all the files down to the very root part. /publish.

How do i make this work, I have tried unchecking Create Manifest in the Project Properties before you publish it and it still creates one.

This is a bad question and i can't really explain it any better. The last time i asked, about a year ago when i was scripting more often I was told to stop sending them to friends. Not really a good answer for what i really needed.

"Windows Client Error" is what my sister says the program is saying when you start setup.

I guess she does not have .NET installed. The only way to avoid this, is to use C++.

Or you could install the .NET framework on her machine, assuming that's what you're using to build your apps in the first place. Smile | :)

As this is posted in the C# forum its a reasonable assumption its a .NET application - language is not important, it still need the correct version of the .NET Framework.

If by any chance its actally VB6 then you need to create an install package.

have you thought of adding a setup project to your solution. In the setup project you will be able to specify which dependencies (.net framework etc) you would like to install with your program.

Hi I do have an managed c++ application.

I would like to write the addin application for my application.
So I went to create the sheared add-in in visitual studio.
Select Create New Project->Extensiblity->Shared Add-in.
The wizard asks for application host name. There are Miscrosoft word, microsoft excel.. etc. How can I make my application, the one I wrote, showed in the host list in wizard?

Thanks

Hi!
I think you're using the wrong approach. Shared Add-ins are meant to be used in MS Office Applications _only_.
If you want your application to act as a plugin host, you'll have to design it explicitely to do so.

Try searching CP, there are several articles about the subject (although I don't know if there are any in MC++, but the concepts are the same regardless of programming language).

DataSet Fill

Hi,
I create a dataset by Add New Item -> DataSet to my project, and add a tableAdapter to it.
Then I used this dataset as a dataSource of a report (crystalReport).
When I Get 'Preview data' in dataset, I see my records, but when running the application my report is empty.
I think I must Fill dataset by some code, is it true? how can do it? or problem is other thing?

Best wishes

Christian Graus4-Jun-08 11:16

I would recommend avoiding all those 'Add New Item->Dataset' and tableAdapter options, if you write actual code, you get a lot more control.

I'll second that. If it's not visible on the form don't add it with the designer.

Of course, I also don't use DataAdapters/TableAdapters or DataSets anyway.

Serialization [modified]

I remember during the class lecture my teacher said whenever you are trasferring an object through wire make that object as a Serialized. I have seen example how to make a class serialized in class and online. But i have 2 questions.

1 But why do we need to make it and why can't i just send an object and the receiving function write
whatever the object contains? Currently i am writing to a file without any seriazation i don't have any problems.

2. In xmlSerialzation how can i update only specific elements and it's sub elements rather than re-writing the entire object which may have so many elements? i.e I do'nt want to write the entire object just the changed data to be written again.

I know I have to search for that speicfic node and then write but any example shall help me alot.

Thanks

1 - Serialisation automates the process of representing the contents of a class as text. If you have another way of doing that, it's going to work just the same, so long as the code on both ends knows how to deal with the stream.

2 - how do you mean, exactly ?

Thanks for answering but...

1. How one can utilize the benefit of represting the contents of a class as text? What about an image in xml file can that be converted to a readable text format.

2. Lets say a parent object that has many different types of child objects are written to a xml file. When a child object is changed only that to be rewritten to the xml file. I don't want to rewrite the entire parent object so i can have quick save functionality.

OK, you have to write the entire file, but you could write code to manage what you're describing, I think. You'd have to cache the serialised text, serialisation by default does not do that. You'd also have to track changes to know which bits to recreate.
