You don't have to convert anything. The oledb field type in Access is equivalent to the image field type in SQL Server.

I am running a process card that has multi-users. Functionality would be to have an autocomplete box in the "dropdownlist" utility. Despite my attempts I am unable to have a keychange event used in the box.
This is the code I use for a combo box to autocomplete, but as my problem is in a dropdownlist, it does not allow me to use a keypress event.
Private Sub ComboBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles ComboBox1.KeyPress
If Char.IsControl(e.KeyChar) Then Return
With Me.ComboBox1
Dim ToFind As String = .Text.Substring(0, .SelectionStart) & e.KeyChar
Dim Index As Integer = .FindStringExact(ToFind)
If Index = -1 Then Index = .FindString(ToFind)
If Index = -1 Then Return
.SelectedIndex = Index
.SelectionStart = ToFind.Length
.SelectionLength = .Text.Length - .SelectionStart
e.Handled = True
End With
End Sub
Please help with any method used to create a keypress event creator.
Regards,
Nicholas

Look around on this site, if you haven't already. There are several articles about AutoComplete functionality...
If you try to write that in English, I might be able to understand more than a fraction of it. - Guffa

Hiya all.
I use advapi32.dll via VB.net to install a service, however I do not seem to think it goes as well as I'd like.
Often when I run the install, everything seems to indicate that it succeedes, but I can't find the service in neither my service list nor registry - although if I use the ServiceController class, I can get a status out on the service.
Similar when I attempt to start or stop the service, the code seems to run fine, but .... alas no service work seems to be done.
Lastly - I am having problems, again similar, with uninstalling - and about 50/50 I either can or can not uninstall (meaning the code runs through fine or not), yet because I can not see my service in the list when installed - I have no visible proof it is uninstalled other then the ServiceController class crashes if I try to get status.
This is the code I am using (VB.NET ... sorry, my company uses that instead of C#  )
<br />

Return False<br />
End If<br />
End Function<br />
<br />
The code is a piecing of stuff I found off the net and some decompiling.
Can anybody advice me as to what I'm doing wrong, or is this method of controlling service installation buggy. I really would preferer such a method as this as I do not really want to call Shell and instalutil
Regards.

How does one get the assembly's Namespace Name?
I embedded some SQL scripts in an assembly. The assembly name is "AAI_TK1", it is in the "ArchiveXpress20" namespace.
Dim asm As System.Reflection.[Assembly] = System.Reflection.[Assembly].GetExecutingAssembly()
--> this returns "AAI_TK1" ----> asm.GetName().Name
However the Resource names are prefixed with the namespace
--> "ArchiveXpress20.Script1.SQL" ----> GetManifestResourceNames()
I didn't want to hardcode the namespace. How can you get your namespace?

Hi,
I recently had the same problem. My solution so far is creating an object OBJ
of a type defined in the same namespace, and then use OBJ.GetType().NameSpace
I too would prefer a simpler solution...

By initializing an 'XmlSerializer' object, you must specify what type of object you will serialize.
Any idea why you must do this by using an 'XmlSerializer' and not when you are using a 'BinaryFormatter' or any other formatter?

I have an enterprise template project on VC7 .NET.
When I enter the "Configuration manager" , I see that in Debug configuration one of the projects is not checked in the "Build" column, and thus this project is not compiled when I am building the solution. I check the project in the Build column, close the configuration manager window. The build solution now includes also the project that was not checked. But when I close and reopen the sln, this information is lost and the configuration manager window shows that project as unchecked.
This seems as a bug of the studio . . . ?!!???, is there a way to make my solution configuration to include unchecked project also?
Thanks in advance,
Julia.

Hi all listeners,
I want to receive two files in a orchrestration from differnet
locations(diferetnt sharepoint sites) and want to construct one of it
accordig to the other.
The scenario is:
first locatuion have number of (around 50) files containing "id" and "rank"
field in each file along with other fields.
I want to create a file containing a heading title and one record for each
file from first location listing "id" and "rank" for each file.
I am plannig for a flow for each file at first location, after this file is
received orch. will fech that "Rank" file from 2'nd location and append one
record for the received file from 1st location.
So i need 2 receive shapes and corrosponding ports.
I have defined correlation set for orch. and initialised it ...now its
giving me error:
"""" In a sequetial convoy the ports must be identical. """
"""" But i want tow diiferent ports for differet loccations
""""
What should i do???
And redig the scenario ...if u have some idea to solve it...please share it
with me...
Waiting for reply......
Mahavir.

Does anyone have conclusive evidence as to wether or not a .NET application can make use of the App Paths registry key? I created a tentative test app and it doesn't seem to find the additional DLLs, but I wanted to get some corroboration.
Thanks,
Scott.

Yes, it can be done. Post your code fragment here, and we can see what's not working.

ednrgc wrote: Post your code fragment here
I would but I don't think the problem is in the code.
I have an application that uses some common DLLs that could potentially be shared by some of our other products. Ideally, we would strong-name these DLLs and put them in the GAC, but (at least right now) I'm not allowed to do that. The next best thing would be to install the shared DLLs to a common folder.
In the installer (InstallShield 12), I create the following registry key:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\Console.exe
(The name of the app in this case is "Console.exe")
and then create a Path string value with the following data:
C:\Program Files\Company\Product\; C:\Program Files\Common Files\Company
When I try to run Console.exe, I get an error saying that it can't find one of the required components. If I copy the DLLs from the common folder back to the local application folder, everything works properly.

I have a problem with VB and graphic. I can generate all the graphics i want but saving is only possible in bitmap.
I need to scale and modify the output of my software with AI or Corel Draw but do not get results. Vectorizing is not an option. I tried various vectorizer lice Corel Trace and the results are not what i expect.

hope u'l respond for my satisfaction.
as far as my introduction is concerned i'm a student of BS doing my final project, i'm using .net since 1 year but crystal reports are new for me.

hi there.
report viewer control is a part of dll so you wouldn't be ablt o use it serperately. there might be some other options, but here is a rough-one.
export the report to a file of desired format and then view in explorer or other application that supports the
format you chose.
Rep r = new Rep(); //report object
r.ExportToDisk(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat , "C:\\myreport.pdf"); //exporting as pdf file
ProcessStartInfo info = new ProcessStartInfo("iexplore.exe","C:\\myreport.pdf");
Process.Start(info);
if you cant find something more robust, this may be usefull, at least on educational level.
regards.

I am doing performance measurements and would like to use a native executable to avoid having JITs occur during performance timing. How does one execute an ngen-generated executable?
There are blogs and MS documentation everywhere that talk about how to use ngen, but I have not found a single place that says how to execute an ngen-executable! 
Here is what I tried. Compile:
% csc helloworld.cs
Then install in the global assembly cache:
% ngen install helloworld.exe
Then go to the assembly cache and try to execute:
% cd c:\windows\assembly\helloworld\[hex string]
% ./helloworld.ni.exe
This gives the error message: c:\windows\assembly\helloworld\[hex string\helloworld.ni.exe is not a valid WIN32 application.
|
|
|
|
|
If I remember correctly, you still run the "normal" helloworld.exe file. The runtime will figure out that you have a corresponding native image and use that instead.
-----------------------------
In just two days, tomorrow will be yesterday.
|
|
|
|
|
I tried that before posting - I don't think it works. The md5 sum of helloworld.exe is unchanged by running "ngen install helloworld.exe".
