I figured out what was happening. Ubound returns a long and I was assigning the returned value to an Integer. This was ok some of the time but when a larger number was returned it caused the overflow. Thanks for your suggestions. Wallace

Some more info that might help. result object is a class that I have created as follows: class HedgeResult { friend std::ostream & operator<<(std::ostream &, const HResult &); public: void clear(); struct Result { std::string resultError...

Hi, I am getting an "Overflow" error when I call Ubound on an object of type Variant numResult = UBound(result) I have tried doing some searching on the net and I can't figure this one out. Has anyone ever encountered this before? The result object looks to be ok when I check it in debug...

Hi, I have an array of arrays decalred as follows: double[][] egArray = new double[19][]; and populated as you would expect. Later in the program there are situations when I want to remove a corresponding row/column e.g. egArray[2][2]. Is there any easy way of doing this without having to...

Hi, I have a VB6 project that contains a reference to a tlb from another .Net project that I have. The problem is that whenever I rebuild the .Net project the reference in the VB6 project becomes out-of-date and I have to re-enter it. Is there any way that the project reference will...

Basically yes. The UserChanged event is fired if the user selects a new item from the drop down. Based on this selection other ares of the screen are loaded with new data. However, there is a part of my application where I pass in the value of the combobox and have to do...

I have gotten it working by explicitly callin the UserChanged event method like this: this.combobox_UserChanged(combobox, null) I'm not sure if it's OK to have System.event.arg set to null though? Thanks

I have a comboBox on one of my forms and when I set the text of the comboBox from another method it does not fire the UserChange event. Is there any way I can force this event to fire so that the component_UserChange method will be invoked? Thanks for any help.

Thanks for the reply. What about the aspect of passing information from one to the other? Would this be easier if i was to create the .Net app as a dll and include it in the main C++ application?

One thing I forgot to add is that when I launch the new application which is basically a form I want to be able to pass some data to it so that it is populated when it opens. Thanks, Wallace

Ok thanks for all the replies. Can you suggest something else that I can use instead of an enumerator?

Thanks for the reply. Given it's 32 bits am I correct to assume so that e.g. 1 << 34 will cause errors? Wallace

I have an enumerator data type and assign the values as follows: enum manualControlList { efirst = 1 << 0, esecond = 1 << 1, ....... ....... eThirtyThird = 1 << 34, eThirtyFourth = 1 << 35, eLast }; However, I think...

Ok found a way around that by converting it to _bstr_t first and then converting that to an RWCString. Any ideas how I can convert a double to an RWCString? thanks for all the help. Wallace
