You can't get them. They're not exposed by anything.

Yes and no. You don't get to control the full functionality of IE. For exmaple, there is no API call to create a Favorites entry. That's nothing but a shortcut created in the users Favorites folder with a URL in it instead of a file path. Other stuff is exposed by the WinInet[^] API functions.

Is there any tool to create a simple line diagram or other diagrams? If so, how can I get it/them?

I can't find any in the toolbox for Microsoft Visual C# 2008 Express Edition, Windows Forms Application.

That's great!

But I can't get the ZedGraphControl in the toolbox. I have added the zedgraph.dll just as it was written in the example you gave me, but I can't find it.

In the "Download C# Sample Project" I can see the control in the form and see the resulting graf if I run the program. But even their the ZedGraphControl is not in the toolbox.

Maybe it's because I use version 2008?

DataRowVersion.Modified is true but Current and Original Values for All columns are equal

I have an application that uses a datagridview to display all the values in a particular datatable, while individual field values for the currently selected are shown in text boxes, comboboxes, etc. below the grid.

Anyway, when I call GetChanges() on the bound datatable, the datatable returned by the GetChanges() method often returns rows as modified even if all the current and original values in that row are equal. When I first load the application, this is not the case, but when I start navigating through the table, each row that I leave is marked as Modified.

Any advice regarding the cause and solution of this "error" would be appreciated.

Thanks.

TabControl question

Evning All,

Can anyone tell me if it's possible to fire an event (add components to a form) when you click on the tab of a 'TabControl'
I've learned that with other components in the form you 'double click' on say.....a button and it automatically takes you generated code that you can add to.

However, when designing the form you can't double click on an individual tab so i was wondering i there is such a feature.

Regards

Neil

There is probably a tab changed event or something. Another option may be to get the click event of the tab control and then figure out which tab was clicked.

Hi,

you want the TabIndexChanged event.
It handles the entire TabControl, not individual pages, so if you need code specific for each page you might want to insert a switch statement there.

As I am very new to this thing... Can anyone who has worked on this type of things, please tell me what is good to use in my situation Virtual Earth or MS Mappoint ?

Thanking in advance.

For Oracle, I use the classes in Oracle.DataAccess.Client

I start with an XML file with a list of databases:

<ORACLEHR Type="ORACLE" Server="servername" Port="8080" Username="HR" Password="hr" />

and pass the information to something like:

string.Format
(
    "Data Source={0}:{1};User Id={2};Password={3};"
,
    Server
,
    Port
,
    Username
,
    UserPassword
)

to produce the connection string.

.NET Interop with Firefox?

DiscoJimmy5-Dec-08 4:26

5-Dec-08 4:26

Just wondering if anyone has tried this. Firefox add-ins are done with C++ and their Gecko API, but me being a lazy .NET programmer and not wanting to get all hardcore again, I was wondering if anyone's tried doing a .NET COM wrapper for a Firefox add-in.

I've made add-ins for another native application this way, but I had help with the COM side of it(by the developer who wrote it in VB6), and so I'm not sure what the procedure would be.

Any ideas?

Dataset empty | Crystal Reports

harcaype5-Dec-08 4:23

5-Dec-08 4:23

Hi. I am having problems with configuring my crystal report. When I attached a dataset to my application, and dragged the table from my newly created database to the dataset, and added a .rpt file which is a crystal report; on the ADO.NET node (which is in the Crystal Report Wizard), I was able to see the dataset I just added plus the table I dragged into the dataset.

However, when I attached my old database, which was created months ago, I cannot seem to view the table I dragged into my dataset. It's always empty. That's why I cannot create the fields needed on my added crystal report. Why's this? And does anyone know how I can deal with this? Confused | :confused:

hi,

does your dataset in CR matchs 100%(variables type) with the store_procedure output(for exemple) from the database?

do you get that kind of error only with images or with everthing?! Frown | :(

I'm not sure. But I'm only having problems with my old database. When I created a sample database and attached it on my CR, it recognizes the tables attached to the dataset. However, with my old database with procedures, the CR wizard cannot recognize them at all. I have no images in my database. Just pure text and integers.

Application shuts down and not just the form

Hi guys,
This might be a broad question for help but I request any suggestions. I have an application in which upon login I hide it with the use of a notify icon. As transactions happen, my hidden app calls another form which works fine for the most part but sometimes the form that I call, upon closing it shuts down my hidden application as well. Is there a way for me to troubleshoot this or avoid this issue.

Please advice.

Thanks in advance

the form which you want to close. the deactivated() event of that form include code this.close();

I don't understand. What do you mean by deactivated event. Instead of using this.close() do you think I should use Form.ActiveForm.Close();
