gah! I replied once before but CP said there was an error, this time it doesn't look like the message was still posted.
Your post triggered something in my memory, but I don't know what exactly. I think someone else may have had similar problems on the DOTNET lists. I did a quick search but couldn't find it, but maybe you can come up with some better hits.

Hey All,
I remember in vb6 you were able to make a single control like a button, visible on all tabs of a tabbed control by holding down alt or something like it while your throwing the control on the form. Does anyone know if this exists in .net?
Thanks,
Ryan

I just ended up putting the control behind the tabbed control and i use the bringtofront method whenever i refresh the screen. I just thought there might still be a shortcut.
Thanks,
Ryan

Hi,
Hope someone can assist with this.
I've got a servicedcomponent running under COM+.
The class requires a new transaction. Connects to a SQL2000 database server running on Windows Server 2003. My development machine is also Windows Server 2003. Neither of the machines are on the domain. Logging on locally to my machine as administrator.
Inside the class a new sqlconnection is created. as soon as open is called on the connection i get a COMException with the following message :
"The transaction has already been implicitly or explicitly committed or aborted"
The method is in a transaction, calling contextutil.isintransaction returns true.
Before this code is called several successfull database commands have been run. None of them from serviced component.
Other client machines, not win2003 server, is running without problems and connections work.
I suspect that this vague error message has got something to do with security or DTC??
If anyone can assist me I would appreciate it!

Is there really no class in dot net to set file association? There must be, right, I can't find it. (That would be such a massive oversight by MS if there wasn't one!)
So can someone point me to a tutorial to do file association in dot net, and also something that tells me how to do resources (like, what is IconPath and IconIndex? I found stuff on file associations but it assumes I know how resources work and I have no clue. I can embed icons in my dot net app as resources, but what is the "icon index" number of the icon once it's embedded?)
thanks

Hi,
I'm working on a ruler control, but it won't be ready until about 2 months from now (because there's more pressing things at hand right now).

:-DI want use DTC to manager distribute transaction directly .I don't like COM+,because of i only need transaction manager,and that i'm worry about overhead.
So,i wanna program DTC as VC++(use olbdb or dblib) in dotnet.
I import the DTC interface through PInvoke,but i can't use ado.net/oledb.net enlist in DTC transaction,want me to wrap native DAO?

There are a bunch of Attributes that mimic the functionality of COM+ ( dtc, opbject pooling, queued components, J.I.T.A., etc. ).
I think they're in System.EnterpriseServices. Hope this helps....

Hi friends
I want to pass a SAFEARRAY of BSTR from a unmanaged code to a managed assembly. My constraint is I can accept just an IntPtr in the managed code. I tried passing SAFEARRAY*, but could not convert it to Array or string[] in the managed code. Can anybody suggest how to achieve it?

Use the MarshalAs(UnmanagedType.SafeArray) attribute or MarshalAs(UnmanagedType.Bstr) . If necessary, combine it with the [in] and [out] attributes.

I have been trying to use unique numbers, but this does not seem to work. The data wizard will always leave them out, and I cannot find a value similar to unique number. Anyway, so I have thought, maybe I should make my own. So I want to know the best way to do this.
Do I, count the number of records, and add one (bearing in mind, data will never be deleted), or do I search through all records, and find the largest number in the column, and add 1 to this? If so for the last one, how would I do that? Would a while loop or a for loop be better? Lastly, in SQL, the column is set to uniqueNumber. Should I use bigInt?
|

Seems a bit odd replying to myself, but I found a solution, so this is for anyone who ever has a similar thing. This is if you want to create your own unique number. The code is:
int test1 = 0;
int test2 = 0;
for (int i = 0; i <= yourDataSet.yourTableName.Count - 1; i++)
{test1 = yourDataSet.yourTableName[i].theID;
if (test2 <= test1)
{test2 = test1 + 1;
}}
Sorry about how I compressed this. It counts the number the number of rows (in the format 1, 2, 3, etc, which is why you must - 1, else you will get an error). The last part just compares the numbers.

Normally you would just set the column as read only and let SQL autoincrement it, or create a GUID.
<a TITLE="See my user info" href=http:
|
|
|
|
|
You could also setup in the DataSet that the column is auto-increment. So whenever you insert a new record, it will create a new ID for you.
There is a problem with this though, as the ID always starts at 1 (or if populated from the Db, the last ID). So if your DB has 5 records in it with IDs of 1 though 5. And you retrieve ID 3 into your DataSet and add a new record, the ID will be 4. Now if you try to save it back to the database, it will error.
Hope this helps

Hi all,
I tried trapping the Up, Down, Left and Right arrow keys in KeyDown, KeyPress and KeyUp. These methods are never called when these keys are pressed.
Does anynone know of a way to trap these keys in the datagrid? I thought I could use the CurrentCellChanged method, but I need to apply something before the cell moves.
Thanks,
Chris

If you want to process the keys yourself you can derive you own grid from DataGrid and override the ProcessCmdKey method such as:
public class MyGrid : DataGrid<br />
{<br />
protected override bool ProcessCmdKey(ref System.Windows.Forms.Message msg, System.Windows.Forms.Keys keyData)<br />
{<br />
return true;<br />
}<br />

How do I know the Width & Height of physical screen in millimeters ? if I don't use DllImport("gdi32.dll") & GetDeviceCaps(hDC.ToInt32(),HORZSIZE) , because it must know hDC first!
thank you very much !

Maybe SystemInformation is what you need.

I have one 'exe' and one 'dll' and I want to provide debug swtiches via config files.
Do I need two config files? (ApplicationName.exe.config and ApplicationName.dll.config) or One is enough?
Don't ![Beer | [beer]](https://www.codeproject.com/script/Forums/Images/beer.gif) and drive.
|
|
|
|
|
You will need one for the primary driver of the process. That would be the app.exe.config
|
|
|
|
|
I already did that. And I kept the config file (applicationname.exe.config) in Debug\bin directory along with the EXE and DLL's.
< ? xml version="1.0" encoding="utf-8" ? > <br />
< configuration ><br />
< system.diagnostics ><br />
< switches ><br />
< add name="MySwitch" value="1" / ><br />
< / switches ><br />
< / system.diagnostics ><br />
< / configuration >
Ignore the spaces.
And declared the switch in both EXE and DLL's in their classes.
private static BooleanSwitch DebugSwitch = new BooleanSwitch("MySwitch", "Debug Switch for Trace and Debug.");
Eventhough I enabled the switch in the config, switch is always disabled.
Did I miss any other settings?
Don't and drive.
