you can use a parameter field, and set it at runtime, you could use a forumla field and change the formula text at runtime to return your value, or you could find a new product to use, i'm traped in the same place you are, trying to make CR dynamic...i've managed to an extent thanks to several online examples and "Crystal Reports .NET Programming" by Brian Bischof(not sure about the first name) but a lot of the features that made it so great for programmers have been removed in later versions the version for vs 6 you could almost build a whole report at runtime, and in 2008 you have to struggle to change anything at runtime, espically with any kind of chart. If you find a good alternative to CR please let me know.

Hello!
I have a question about retrieveing a toolstripmenuitem from a contextmenustrip.
In a certain function I do the following:
contextmenustrip.Show();
After that I would like the function to be halted until one of the toolstripmenuitems is clicked and this item is the returned into the funtion.
So I don't want to use an event but rather something like one can do with forms:
if (this.TestForm.ShowDialog(this) == DialogResult.OK)
Is something similar possible with contextmenustrips?

As far as I am aware their is no way to emulate a ShowDialog method for a menu. If their is a such a way you would have to work with Windows API or advanced menu events.

I have to read a large quantity of bianry data from a file and then store this data in an XML tag. There is approximately 8 MB of data.
This can be slow just to read the 8MB into memory using StreamReader.
I tried reading sayy 500k at a time. But i still have the issue of storing 8MB into memory.
If i would have just read 500k and then write 500k, i would be ok. But i am using XMLTextWriter that does not allow me to write tag data piece by piece. I have to have all the data and then write it to tag.
Any suggestions on how to handle this effectively will be appreciated.
Thanks,
cw

if you are just saving binary to XML you'll double the size of your data. If you encode it to base64 it'll only be about 4/3 the orginal size, but with conversion overhead.
Why do you need 8MB of binary data in XML anyway? To me it sounds like a design flaw not a memory issue.

I actually do encode to base64. It does not even get that far as it is stuck reading all the data from the file.
The reason i need to do it this way is because another application creates this data(video) and dumps it to a folder.
My application has to read it in, and put in an XML tag along with other data pertaining to it.
Any ideas to make this process better from a bandwidth perspective?

I have an app that uses filewatcher to monitor a directory. When a file gets in the directory it reads it, pulss out the jpeg and other data perfectly. Now i would like to display this data on the screen. I have created a picture control and some text controls to dsiplay this data. Anyone have some guidance or good source examples on how to do this?

You can use a WebBrowser control to show both images and text.
Best regards,
Jaime.

Any documentation or quick examples on how i would use this control?
I am sort of new to this.
Thanks,

a web browser is not a good fit b/c it shows stuff in a pretty defined way. Just use labels to show text, and pictureboxes to show a picture. Bitmap.FromFile will load the image from that file for you

Hi all,
I've created a user-control, which resides in library of other controls I use in my application. The control has two or three textboxes and some drawn graphics. I've put this control in my main application and it basically works fine.
Next I have a class, and I create an instance which stores my data and I serialise this class to file for use later on. The user-control is used to change the values in this object and I do that using an event which is fired when the TextChanged event occurs. What makes it more complicated is I can have multiple instances of the class which I need to switch between and the user-control needs to display the data in the textboxes for the objectI've selected.
My problems see to start when I reload my serialized file or switch between the objects.
So for example, when I initialise the control I do:
usercontrol.textboxA = X.GetParamA;
usercontrol.textboxB = X.GetParamB;
When I switch between say object X and Y I do
usercontrol.textboxA = Y.GetParamA; // This can cause issues as TextChanged is called
usercontrol.textboxB = Y.GetParamB;
When the user changes a value in the textbox I fire the event which is caught in the form containing the user-control I do:
// Get selected object X or Y in this case
Y.GetParamA = usercontrol.textboxA;
Y.GetParamB = usercontrol.textboxB;
This really doesn't feel like the right way to tackle this and I fear my design is off. I though of passing in a reference to my objects or maybe there is a better way to use the events...
Any suggestions would be great.
Thanks

Looks ok to me, remember most of your work revolves changing data from one format to another and vice versa.

Hi guys.
How can i execute or fire an event, by example the Validated event for a textbox control from another control like a button?
Example:
I have the following code for the Hello textbox Validated event:
private void Hello_Validated(object sender, EventArgs e)
{
MessageBox.Show("Hello guys");
}
I want to fire that event, the Validated event from another control like a button, so i can show the message "Hello Guys"
by clicking a button.
Thanks for your time...
Regards...

private void Button_Click(object sender, EventArgs e)
{
Hello_Validated(null, EventArgs.Empty);
}
I doubt it. If it isn't intuitive then we need to fix it. - Chris Maunder

Just call Hello_Validated function from the part of the code you wish.

Can't you at least be polite when you criticize someone? At least the code is reasonably formatted if not in pre blocks.
