the code as you typed it there wouldn't compile, so I tried this:
.Cells(1,1).Activate()
excelApp.ActiveCell.Font.Bold = True
excelApp.ActiveCell.Color = 10
The code compiled and the program ran perfectly, however the font was not bold nor was the color changed when I opened the excel file. Does the fact that I'm using VB.Net change anything?
I love to program!

I tried the code you gave and ActiveCell isn't a member of the worksheet class. I have worked with VBA but not enough to know how to convert between VBA and VB.Net. Thanks for all of your help though.
I love to program!

try worksheet.range("A3").font.bold=true

How do I create a datagrid in Visual studio,
populate it with 3 database table fields
and display it on a web page
|
|
|
|
|
Hi, i have been experimenting with the clipboard in vb.net and have been able to copy to/paste from the clipboard as following:
If Clipboard.GetDataObject.GetDataPresent(DataFormats.Bitmap) Then
'setting clipboard data to picturebox
pbxMovie.Image = Clipboard.GetDataObject().GetData(DataFormats.Bitmap)
End If
Now, this works fine within applications. for example i can copy to/paste from word and also in my applications. but when i try to copy something form my desktop or harddisk, it doesnt work.
Also when i try to paste on my desktop/harddisk, it simply isnt in the clipboard (no 'paste' option in the context menu)
Anyone got any ideas?

If you're copying/pasting stuff from the Desktop or a Drive, you're not working with an image, you're working with a filepath. Copy something from the drive, then check the types of what is stored on on the Clipboard.

You may use a link with href something like this one:
< a href = "Form1.submit()" > [Your text] < / a >
I dont know whether it is a good solution b ut I got the same problem like you before.
Hope it helps,

To deploy your application, you need to create a setup project and add the necessary merge modules to your application before you build your solution.
Open your Windows application.
In the Solution Explorer, right-click your Windows application solution, point to Add then click New Project.
In the Add New Project dialog box, select Setup and Deployment Projects in the Project Types pane and select Setup Project in the Templates pane. Click OK.
In the Solution Explorer, right-click the Setup Project, point to Add then click Project Output.
In the Add Project Output Group, select Primary output and click OK. Any dependencies, such as the Managed.msm, are added automatically.
In the Solution Explorer, right-click the Setup Project, point to Add then click Merge Module.
In the Add Modules dialog box, select the following merge modules to add to your Setup project and click Open:
Database_Access.msm
Database_Access_enu.msm
regwiz.msm
For a description of these merge modules see Crystal Reports Merge Modules (ms-help://MS.VSCC/MS.MSDNQTR.2003JAN.1033/crystlmn/html/crconcrystalreportsmergemodules.htm). Note If you deploy a Windows application that uses an ADO .NET dataset, you also need to include the VC_CRT and VC_STL merge modules.
In the Solution Explorer, right-click the regwiz.msm file and choose Properties.
In the Properties window, expand MergeModuleProperties and enter a valid license key in the License Key properties box. Note Providing the license key is a mandatory step whenever you deploy a Crystal Reports for Visual Studio .NET application. A license key will be given to you once you have registered Crystal Reports for Visual Studio .NET. You can find the license key in the About dialog box. From the Help menu, choose About Microsoft Development Environment. The keycode is listed in the Installed Products field.
From the Build menu, choose Build Solution to build your application. When deploying to a client or server computer.

hi!
as far as i think ur connection object is faulty create cnnection object with appropriate parameters.. like if u r using sqlconnection it would be
dim constr as string="server=[servername];user Id=[username/sa];password=[pwd/""]initial catalog=[database name];"
dim con as new sqlconnecton(constr)
better if u would send connecton code as well..
GoodLuck!!

No need 2 create that its already there..
follow link

enjoy!!
Sufyan,

Thanks for reply
But I have seen these all links of multiColumnComboBox
They are not working with my datagrid
The link which u suggest has the limitation that it limits the Column Numbers (Only 4) for the MultiCOlCombo
http://www.codeproject.com/vb/net/MultiColumnFlatCombo.asp[^]
So I want to generate my own Control
So that that control can be embed with datagrid.
I think Controls can't be added with the DatagridTextBoxColumn
I m right/not????????

Hema!

hi SUfyan,
Thanks for prompt reply,
Acutally i have craete a userControl in vb.net for multiColumn COmboBox
But when I embed that User Control that will not work???
But If i add a toolbox Contorl like CheckBox etc they are working fine with the datagrid.
So I find the conclussion that
1. There may the problem with my user control(Although its working fine on Form)But not with that datagrid.
2. There may a chance that the winforms datagrid may not support User Controls.????????????????
Hope for early relply
Thanks a lot
Hema Chaudhry

|

Well!
i think first problem option my b there otherwise if simple control gets added then user defined control should be added as well..
thanks

Neither really. The StreamReader/Writer classes wrap the Win32 API functions.
