Why don't you wrap the two controls into a new custom control that you create yourself?

You can write in the event that you want that fitting to be fired that code:

//on the event here<br />
private void Onfitting()<br />
{<br />
    Point Differnce = new Point()<br />
    Control1.Location = new Point(0,0);<br />
    Control2.Location = new Point(Control2.Location.X-theDeffernceBetweenthem.X,Control2.Location.Y-theDeffernceBetweenthem.Y);<br />
}

RemovePreviousVersions Feature

Hi all,

I have one question about setting up the installer. I've set the RemovePreviousVersions of installer to true, and have changed the installer version every new release(it also changed the product code).
However, the installer still can't detect the pervious version of application. Do I miss any important steps?

Could you please hlep.

Regards

I had the same problem. IIRC the version numbers need to be incremented too, but in my case it didnt work. Some silly issue with MSI not checking the entire version 'string' (0.0.0.1 -> 0.0.0.2 didnt work).

^{xacc-ide 0.0.15 now with C#, MSIL, C, XML, ASP.NET, Nemerle, MyXaml and HLSL coloring - Screenshots}

for me, my previous version number of installer is set to 2.1.0
now I set the installer version to 2.1.9 , it still doesn't work.

A strange issue, I was changed back the RemovePreviousVersions to false, however, the installer will go to install page without any prompting. As it will ask user to remove pervious before, now it can't.

I really don't know how to solve.

Creating a custom Combobox control

Is it possible to create a custom drop down control much like the existing Combobox, but with my own content on the drop down area? I have special needs, for instance to include a Textbox and a Button on the drop down area.

I cant figure out what kind of window the drop down area is. It must be a window since it can cross the parent form boundaries, but at the same time it doesn't remove the focus from the parent window so it acts like a regular form control. To create such a "hybrid", do I have to use the NativeWindow class, or has it all to do with redirecting window messages from the popup window to the parent window?

The ideal situation would be to have some kind of free floating "PopupPanel" control that could be added to a form, but that isn't restricted to parent form boundaries. Any clues on how to write such a control?

Then the panel would no be able to be shown outside the parent form boundaries, for instance sticking out over the bottom edge of the parent window.

I got help from Tim Wilson to find this article that solved my problem:

Here is an example using ADOX. Just import the ADOX COM object as a reference.

ADOX.Catalog catalog = new ADOX.CatalogClass();
catalog.Create ("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\\mydb.mdb;Jet OLEDB:Engine Type=5;");

ADOX.TableClass table = new ADOX.TableClass ();

table.Name = "NewTableName";
table.Columns.Append ("MyColumnName1", ADOX.DataTypeEnum.adInteger, 0);
table.Columns.Append ("MyColumnName2", ADOX.DataTypeEnum.adVarWChar, columnSize);
table.Columns.Append ("MyColumnName3", ADOX.DataTypeEnum.adDate, 0);

catalog.Tables.Append (table);

You can also check out xsd2db. You can load the project and use the code that it uses to automatically generate an access database from an XSD.

Hi @ all,

I want to copy the contents of a richTextBox to another without loosing the text styles.

richTextBox1.Text = richTextBox2.Text // copies the text contents without the styles

or is there any option to set or an other additional store to keep the styles with the text ?

Thank in advance
Frank

I haven't tried this, but from the docs it looks like if you do

richTextBox1.Rtf = richTextBox2.Rtf;

that will do what you want. The .Rtf is supposed to contain the text, including the RTF formatting codes.

I want to update a Jet 4.0 database using databound textboxes. I was trying to find some examples of how to do this on the Net, but all of the examples that I could find were using datagrids. Does anyone know of a online example that updates a Jet database using databound textboxes. I am using a OleDbDataAdapter.

Thanks.

There is no difference weather you use textbox's or datagrid's. Both are just a method of displaying and editing data. The updating is done by the DataAdapter.

lets say i have tabpages with lots of textboxes on each page. (winform)
is there a shoort way to empty all textboxes on each page?

Re: empty textBoxes

techieboi21-Mar-05 6:58

I use code like the following to set control's to their default values. You can either pass in the tab page to the function or modify it slightly and pass in the tab control and step through the control's pages.

private void ClearTextBoxes (Control parentControl)
{
// Step through each control in the parent control and clear it's text if a textbox
foreach (Control control in parentControl.Controls)
{
if (control is System.Windows.Forms.TextBox)
control.Text = string.Empty;
}
}

This method has the added advantage that you can also default check boxes' and other controls' properties by adding an additional if (control is [control type]) statement in the for loop.

Hope this helps

You could put the second .EXE as a resource into your primary .EXE. But! You still have to unpack it and put it back into a file on the hard rive to use it.

Bottom line is, you can't, unless you rewrite the second .EXE functionality into your primary app.
