Code comming from a network source runs under a lot more restrictions than if you were to launch the exact same code from the local hard drive. Use the .NET Framework configuration tool in your Administrative Tools folder to increase the trust for that code running from a network zone.

I know it is possible to enable your .NET applications to use Microsoft .NET Passport.
Yeah, but ... how to do that? It is free of charge or a subscription is needed?
If anyone knows something, please help!
Thanks

You might want to start by reading the Business Implementation[^] section of the .NET Passport SGK documentation.
AFAIK, there is no subscription fee. But there may be a compliance checkout and fee before your site is allowed to go into production. I have no idea what that charge might be.

Hmmmm... it seems to be a mystery. However, thanks a lot, you have completely *resized* my problem.

Is is possible to access a USB Flash drive / disk from the .NET framework.
I want to be able to detect when a Flash drive has been inserted, write to a CF and then allow the user to safely remove it.
Will .NET 2.0 have this capability?
Thanks,
Liam

When you put in the computer doesn't it just show up as "Removable Storage" or something? It's acting like a hard drive, so if you just want to save/read files on it, just use the normal steps.

When I boot I will boot directly to my application and bypass the standard windows environment. There will be no task bar available to the user.
So I have to mimic what is done in the task bar in a programmatic way within the C# code.
Thanks,

Hello Everybody !
Does anybody know, why in some articles here, and also in VS.NET -generated Databound form the following logic is used to save DataSet changes to database:
SaveChanges(){
DataSet datasetWithChanges=dataSetUsedByControls.GetChanges();
if (datasetWithChanges != null)
{
SaveChangesToDB(datasetWithChanges); // function where adapters save changes to db.
dataSetUsedByControls.Merge(datasetWithChanges);
dataSetUsedByControls.AcceptChanges();
}
}
I tend to use:
SaveChanges(){
if (dataSetUsedByControls.HasChanges())
{
SaveChangesToDB(dataSetUsedByControls); // function where adapters save changes to db.
dataSetUsedByControls.AcceptChanges();
}
}
So why GetChanges - apply them and then merge with original dataset ? We can simply pass the originald ataset to adapter and changes will also be saved.
Can anyone explain why Microsoft has implemented the first variant it it's data-bound form wizard, and also why some articles use this variant as well ? Where is the trick ?
For example here:

DataSet newbie wrote:
DataSet datasetWithChanges=dataSetUsedByControls.GetChanges();
The dataset "datasetWithChanges" is a new dataset that only has the records from the "dataSetUsedByControls" that actually has changes. Therefore you when the execute the
SaveChangesToDB(datasetWithChanges); //Notice it is the smaller dataset being sent
less network traffic is generated and therefore faster performance. Then the datasets are merged. Your way sends the entire ds back including all the records that do not have any changes to them.

Thanks, and Stop !
We should clear out the configuration where the code works (I had to write it in my first post probably):
If this is a Local Windows Forms application, then dataset and data adapter are on the same machine, so
during SaveChangesToDB(dataSetUsedByControls); //full dataset
dataset is processed locally throught the adapter and adapter applies only changed data to datasource.
If I understand you, you talk about some distributed application, where dataset and dataadapter are separated through some communication channel, right ?
So If I did understand you correctly this means:
1.Use GetChanges-Update-Merge for Distributed applications
2.Use direct Update from Full Dataset in local applications (this will even have some performance gain, because we avoid creation of new dataset and, later, Merge)
right ?

MSDN states that on the acceptchanges method ALL rows of each table are updated. So in my situation, which you are correct is distributed, I extract a smaller dataset to send to a webservice. The webservice hooks the dataset into the dataadapter and performs the update.
IMHO, on a local app then I would probably find out how much data actually got changed, if a small amount (<20% perhaps) then create a new dataset and only process it. But if a significant amount (>70% ?) then why waste the resources of creating a new dataset, just update with the acceptchanges like you are doing.

The truth is somewhere near.
Generally I think that .GetChanges has sence for distributed case.
The costs are:
Case with Merge:
GetChanges (full iteration through full Dataset) fi
Update (iteration through subset) si
Merge (iteration through Full Dataset + subset) fi+si
totally fi+si+fi+si=2*fi+2*si
Case with direct update:
Update - full iteration
AcceptChanges - full iteration
totally 2*fi
Also look here:

I have created a service but I don't want users that have "local admin" rights can uninstall it.
I deploy this service via MSI Package and GPO, so an entry is added in "add/remove programs".
How can I add a password in the MSI Package which will be asked during the uninstall ?
|
|
|
|
|
You would have to create a custom DLL action that asks for the password during install, which is a process far too complicated to outline on this forum.
A better question would be why you need to address this in the first place? I know I would be pissed if I couold not simply uninstall anything that was installed on a system that I had admin rights to.

Hello
I'm trying to deplay a .NET assembly to workstations. This .NET assembly should be registered with regasm.exe (for Com Interop) and placed in the GAC. Using gacutil works fine as a developer but whenh users run the command file (containing various copy, regasm and gacutil commands) the permission to install is not enough. Example:
<cut>
gacutil -i VspJKofaxValidationSupport.dll
Microsoft (R) .NET Global Assembly Cache Utility. Version 1.1.4322.573
Copyright (C) Microsoft Corporation 1998-2002. All rights reserved.
Failure adding assembly to the cache: Access is denied.
What could i do without digging into a completely different way of deploying? Project time is running out

Hello All,
Can anyone tell me how to resize a textbox to fit a given string? The textbox must keep the same width and adjusts its height to properly display whatever text I put in it.
Thanks!

Ok one other thing...
I'm thinking of doing something similar with the Label Control as well...

Hey folks, i got a problem...
i got a third party app randomly connecting to 200 different servers.
All servers got a fixed IP that i know.
Now i want that app to only connect to a defined server, lets say server 120.
Is there an possibility to redirect all the other server ips to the ip of server 120?
I don't know if the app has to resolve the ip first but it seems so already tried to manipulate the "hosts" file but the app doesn't care...
If you got any idea pleas let me know... even if its as silly as hell
thanks

Hi all
I have a customer who wants to implement all the password policy available.
According to microsoft password policy settings, there's only enable or disable. 
- English uppercase characters (A through Z)
- English lowercase characters (a through z)
- Base 10 digits (0 through 9)
- Non-alphabetic characters (for example, !, $, #, %)
Is there a guide I can refer to to create a bypass so as to build in all 4 policy settings? 
Thanks in advance.
Thomas
