I have a large project which consists of about 60 modules. It contains a lot of DataGridView components.
Recently I implemented cut-copy-paste functionality to one of the DataGridViews.
What is the best way to add same functionalities to all the other DataGridViews .
P.S. I don't want to create a new component which inherits DataGridView and re-define all the DataGridViews.
I've tried to implement directory listing using the Webbrowser component, I dont need much, just to display some directories, be hable to click them and then be hable to see its contents and be hable to see the images and files inside. the problem is, the default behavior of the webbrowser component is, any directory link you try to click. it will inmediately make either IEXPLORER or MS Explorer to run (in a new window) and open the directory. I just want the webbrowser component to let navigate freely on directories. What can I do to implement this? Just to Clarify: I just want webbrowser to open the directories and files IN THE SAME WINDOW and to not run the MSexplorer like it does by default.
View 4 RepliesI have a purely XML database. It's stored as XML, there is no other database file. I did this by first creating a dataset in VB, then adding tables and relationships. I load the database by calling DataSet.ReadXml(FilePath), and save the database by calling DataSet.WriteXml(FilePath).
Now I need to make schema changes, but need to preserve existing data. How might I go about doing this? As soon as I load the database I loose all data if I change the schema in the dataset designer.
I have searched for changing database schema, but everything I find deals with real databases, not XML only ones, and the info doesn't apply because they are using db connections and then running sql against it and AFAIK XML databases have no way to "connect".
I have an Excel template that contains numerous pre-defined charts and a program that opens this template and collects data used to populate the charts. This works great but I now want to adjust the series length so that the charts only used the data collected (not a range of 32000). I'm trying to iterate through the charts and determine the range for each series of each chart but not having much luck. The snippet below allows me to see the xvalues but does not return any information as to where this data is located. Does anyone know how to extract the range for each series in a chart?

I've created a component whose name I'd like to be able to change while editing in the component tray. I've added a Designer action for a name property, but now I'm stuck.
Looking at the property grid, I can see that the name property is parenthesised, indicating that it's not a regular property.

I have a workbook (Workbook1) that runs through some steps using visual basic, which ends up opening another workbook Workbook2). Once Workbook 2 is opened, I need to copy a section of data from it, into Workbook1 int a specific worksheet. I was able to do this by recording a macro, but the challange is, the name of Workbook 1, and Workbook 2, will vary by User. When I created the macro it uses the files as they are currently named.

View 4 RepliesIs there a good web browser component for VB.NET that has all the features of the regular one? This includes printing and progress bar support. I've tried WebKit.NET, but it didn't have progress bar support. I also tried xlurunner but it had no printing support. Is there another web browser component that has both printing support and progressbar support? I shouldn't have to omit features from my browser just to get a better rendering engine.

View 2 RepliesI'm making some archeology, dealing with COM+I managed to enlist a simple COM dll as a COM+ component, so far so good.So I've got this 'foobar' com+ component, with it's interface, and the method I'd like to call.My question is then rally simple: how am I supposed to make a call to this component?.NET or VB6 answer is accepted (I have to check the component is OK, don't care about the client)
Edit (06/03/09): Well, I'm confused. so as to work properly, my COM+ component needs it's dll to be registered. Why not? But then, how to be sure I'm making a COM+ call, and not a COM one?
I have a function to determine the correct time that appears to function correctly, but I must be making some mistake in the "calling" of the function. This is the first time I have tried use a component and it shows.

View 2 Repliesi have just quick question (there's not much to elaborate from OP site). Have you any links or ideas, or experiences, what is to be done to class derived from System.ComponentModel.Component, in order to show its rectangle in designed form or control. I maybe satified with just making Component shapy. Anything else should be just game. But actually I have no idea how to draw component from its basics. Any idea or link, or bunch of links very welcomed! Even my capabilities of crunching google links are nothing here.

But I can't say they're straightforward. First link looks good, though its C# WinForms realization doesn't allow simple re-using in VB.NET project without conversion.I only need to burn a list of files to a CD/DVD and that's it. Any thoughts? Freeware/open-source is preferred.
I didnt know if this was the correct location to post this kind of question. My code is in C# however I am using the visualBasic. Interaction. CreateObject to connect to a OCX file. I notice that this works great for a while but if it continues to do its job for lets say a few days then I get and exception... "Can not create an ActiveX component."
