64-bit Error With LayoutKind.Explicit?
Apr 7, 2010
I run understanding code in my bridge program to call the double dummy solver dds.dll.
<DllImport("dds.dll", CallingConvention:=CallingConvention.StdCall)> _ Public Shared Function SolveBoard(ByVal deal As dealstruct, ByVal target As Integer, ByVal solutions As Integer, ByVal mode As Integer, ByRef tricks As futureTricks) As Integer End Function <StructLayout(LayoutKind.Explicit)> _ Public Structure dealstruct <FieldOffset(0)> Public trump As Integer <FieldOffset(4)> Public first As Integer
[code].....
After filling in the variables, the double dummy solver is called by:
calldll = SolveBoard(dealStr, target, solutions, mode, futureStr)
With a 32-bits machine this code is functioning correct, but with a 64-bit machine the code generates next error code:
System.TypeLoadException:Could not load type 'Dealstruct' from assembly B-Bridge version 1.1.7, Culture=neutral, PublicKeyToken=null' because an object field at offset 20 that is incorrectly aligned or overlapped by a non-object field.
hich adjustments I have to make to the code so it will function correctly on 64-bit machine.

If default 'sa' account has sys_admin permissions for the whole SQL instance and all its databases. On the database itself, if I don't have db_datareader permission enabled, I would assume it doesn't need it as it is implied but I was wondering in .net, is there way to check if db_datareader has explicitly been enabled and not just implied from the 'sa' being a sys_admin.

What are the main functions needed to create a .dll file in vb.net which needs to be Explicitly linked i.e at run time to an application Plz post me an equivalent code snippet in VB.Net
Explicit run-time linkingDLL files may be explicitly loaded at run-time, a process referred to simply as run-time dynamic linking by Microsoft, by using the LoadLibrary (or LoadLibraryEx) API function. The GetProcAddress API function is used to lookup exported symbols by name, and FreeLibrary — to unload the DLL.

In C# you can define explicit add/remove code when an event is subscribed/unsubscribed.
Is this possible in VB.net?

I have some code I inherited which has a lot of warnings that I would like to get removed. Many are of the form Property '<propertyname>' doesn't return a value on all code paths. I know why it is saying this, I'm just trying to determine what the correct 0 impact way of fixing this is.[code]Unfortuantely if I put this in my code (having changed the local variable name to avoid collisions) it then complains that it is being used before it has been assigned a value.Try to analyze IL in LinqPad (not sure if this is a good test or not) reveals that the empty method is the same as the above that Reflector gave me but it is different from return Nothing and return "".What can I use to get rid of this warning while guaranteeing the code runs 100% the same? [code]I'm not sure what ldloc.0 does here. I'm wondering if it is trying to get something from a register which will be null and if that is therefore the same as ldnull in this situation but I havent' ever really studied IL much before...

When creating a T4 template in VB.NET, how do you specify Option Explicit, Option Strict,and Option Infer settings? There's some sort of <#@ #> tag for doing this, but I can't find it.

I need to explicitly load my data source variables and then call the insert method associated with the data source. The sample VB .net code is listed below. So is it sufficient for me to just call the Insert() method when I am ready to insert my values? Or do I need to create an insert event? You see if I look at the properties window for the data source, there is a lightning bolt icon that will generate events for the data source such as Insert,Inserting,Disposing,Init,Load etc.
Protected Sub btnSave_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Me.SqlDataSource1.InsertParameters.Add("@Title", "Mr.")

Using VS2008, targetting framework 3.5, trying to update some VB4 code. Yes, VB4.I have a bunch of legacy code I'm trying to update, and I had the idea of trying to work through it by executing the old code, working out what was causing each error as I came to it, solving the problem, and then moving on.In order to do this, I have sinned and set Option Strict Off, Option Explicit Off and Option Infer On.Yes, I'm going to hell for this.Problem is, I'm still getthing errors that various things haven't been declared.All of these the items showing errors are in the form: itemName(obj)Is my problem that the compiler thinks that these are method calls for methods which haven't been declared?PS: For anyone wanting to tell me not to use these settings, I already know

When I deployed my project on a server, in certain circumstances, I get an error page that indicates I should create a custom error page. I was wondering how exactly I would implement this custom error page the server asks for to give me a precise and helpful message or preferably, how I would get the error to just display on the main page?This is the error message I got below
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
[code]....
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.
<!-- Web.Config Configuration File -->

<system.web>

This error first appear to occur randomly. Steps to recreate:Open Visual Studio and load a solution (some files automatically opened) - this is when the problem occurs Close all open files Restart visual studio and load solution (no issues)Open Exactly the same files again, restart visual studio and load solution so files open automatically (problem occurs!)
However, when trying to narrow it down to a single file (that is automatically opened when the solution is loaded), I couldn't reproduce the problem. Now with all the files open again the problem doesn't occur!!! So it looks like it is fixed - though this happened before and eventually the issue came back.
I think it is to do with one of the user controls with DevExpress controls on it - when the error occurs, the designer displays the error. Though I can't reproduce it at the moment to confirm that.

I got a serious problem. Though I have made my program newly it shows error. I have used 1280,1024 animation only for first form then used 1280,1024 image for every form. Today I was checking then it was showing me error message for 19th & 20th form. If I use On Error Resume Next then it shows error for another form ; if I use same code there in the menu item I mean so that I can get rid of error when I click to show a form it shows another error. First error message is "InvalidOperationException was unhandeled An error occurred creating the form. See Exception.InnerException for details. The error is parameter is not valid." and second error is "OutofMemoryException was unhandled Exception of type 'System.OutOfMemoryException' was thrown". I have noticed it that it doesnt show error message for those form which have few labels and text boxes. It shows error message for those forms which have 1 menu bar, 2 picture boxes(one is 1280,1024 & another is 250,456), 2 group boxes, 40 labels, 3 combo boxes, 38 text boxes & three buttons. Please help me I need to get rid of this problem. Does it mean that I cant use unlimited control there in my form?

I have the following Stored Procedures create or replace PROCEDURE WEB_AC
[Code]...
First one: At some point in the application I have the valor parameter (of the visual Basic Function) as a string with spaces that is something like "some string with spaces". When this happens, the stored procedure don't update the table. If I execute the SP directly in the DB (with SQL Developer) all works fine. I know it has something to do with the string missing some quotes(') but I haven't make it work yet. Some ideas on this?
Second problem: Sometimes, when debuging the application, if I interrupt the execution, I start getting the ORA-24338 'statement handle not executed' error for hours every time I try to execute it again. I believe it has something to do with an open transaction. But honestly, as I'm new in working with Oracle, I really have no idea what the problem could be.
