• Smart Device Development Is way to Override the Disabled appearance of ListView Control

  Hi all, is it possible for me to override the appearance of the ListView Control when its enabled property is set to False (disabled) I guess I need to change the colour as when the ListView Control is disabled, its very hard to actually see what value is selected if there are only two entries in the ListView. Thanks I do not even want to select an item from the disabled ListView. What I am asking to see if I can override the backcolour of the ListView when it is in the Disabled state because at the moment in my application when the control is disable and there are two items in the ListView (one of which is selected) and its disabled (I select an item in the ListView then disable it) it is very hard to actually see what the selected ...Show All

• SQL Server Advanced SQL Generation Options in VS2005

  Hi There im not sure if im in the right place but i was wondering why the above option is greyed out when creating a new sql datasource. This occurs even when i select all fields within the table (including primary key fields) Thanks Todd limonada wrote: One thing I noticed is that the option is grayed out if the table used in the select statement has no primary key, which makes sense, since UPDATE and DELETE operations on a table without a primary key are very specific to the logic behing the table and cannot be generated automatically. This is what I found as well and it's worth mentioning again as I spent ages before realising what I was doing wrong. It is not enough to just have a primary ...Show All

• SQL Server OpenQuery() to Linked Server hangs, leaving SPID with open tran, then templog.ldf grows without limit.

  Hi, We have a customer that is using SQL Server 2000, and experiencing the following intermittent problem -- occasionally templog.ldf will grow and grow until it fills the entire disk. This is a rare problem, it has happened less than 10 times in the past two years, for a job that runs once a minute. But it has happened on 3 different SQL Servers, (two production servers, and one test server). Our suspicion is that the root cause is an OPENQUERY() to pull data from a linked server (Oracle database on Unix). We have seen that these OPENQUERY() statements occasionally hang and cannot be killed. The OPENQUERY() is used to populate a local table, and when we originally populated permanent tables with OPENQUERY(), then there would be a ...Show All

• Visual C++ How do you create a pointer to class funcitons (not members)?

  Hey, I was jsut wondering, how do you create a pointer to a function that is a member of a class Note that I don't want to make a pointer to member, I just want to be able to do something like this: class ClassA { public: void SayHello() { MessageBox(0, "Hello", "", 0); } }; int main() { ClassA a; void (*ptr)() = a.SayHello; // this would be how i would suspect it to be done ptr(); } How do I acomplish this Glad to help. Note the original poster gave in that thread didn't follow directions and his code sample wasn't what I suggested.

• .NET Development Can I open an Access database from vb .net if the mdb file is opened.

  if I try to use the following connectstring "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\\cse1\src\test.mdb;Mode=Share Deny None;User Id=admin;Password=;" I get the following error "The Microsoft Jet database engine cannot open the file 'test.mdb'. It is already opened exclusively by another user, or you need permission to view its data." I was assuming that mode-Share Deny None would open the database in read-only mode, since I have to just display data and not do any updates. thanks. Yes you can open/read/write to an acces db when it is opened by another user (access is a multiuser DB),  However you can NOT when it is opened exclusively by another user...you may also want to make sure tha ...Show All

• SQL Server Unable to set Identity_Insert Off?

  Hi i am unable to set Identity_insert off in sql server compact Can you please tell me if sqlce supports or not If it does not support what is the work around that can be done Please tell the workaround in detail i mean altering table for identity key e.g. Because i have seen some posts that talk about alter table but i am unable to understand how that can done Thanks I discuss this issue in my EBook and I came to the conclusion that until Microsoft beefs up the Identity tools (as you discovered), it makes more sense to use my own ID generation routine or GUIDS. Consider that the database is single user. This means there is not a chance that another user will collide with some of the more rudimen ...Show All

• SQL Server BI Portal connected to analysis services 2005

  Anyone has connected the bi portal with analisys services 2005 I have a security problem. Thanks Sorry, I don't know. I cannot enter a connection string directly into the advanced box, but if I connect first, or if I click Advanced and then browse and select a .oqy file, I can then edit the connection string. I have not used BI Portal extensively, maybe you have an issue with your installation. The main reason I suggested that you try a simpler connection string was the the sample you provided had the Initial Catalog setting listed twice and you had a User Id and no Password set, even though User Id only works with HTTP connections. You could try creating an OWC page outside of BI Portal just to test the the OWC co ...Show All

• SQL Server Windows authentication

  I've got an application that's supposed to use a combination of Windows authentication and Custom authorization, here's how. Only the administrator can add users, venues, and booking types.

• Visual Basic filling a bitvector32 in a loop

  Dear all, I can fill a bitvector32 like this: Dim InBytes As Int32 dim i for i = 1 to 1000000 InBytes = i 'for example Dim InBitVector As New System.Collections.Specialized.BitVector32(InBytes) next i and then I can read out the individual bits (need this for a graphics conversion). Problem: this gets VERY slow, and I trailed that to the Dim InBitVector statement. Is there ANY way to assign an Int32 number to the InBitVector WITHOUT using the dim statement Thanks, Kees Hi Renee (not a guy, I guess, from the double 'e' ), I am unclear how the bitconvertor.ToInt16 is going to help.
