c# - Image button on visual studio 2010 -

-

i trying create button image , no text [design] view on visual studio 2010. drag & dropped button, click image property, select png image resource file, property remain empty , button doesn't have image neither on [design] view or in compiled program.

i tried setting image on form.designer.cs file with:

    //      // button1     //      this.button1.location = new system.drawing.point(73, 11);     this.button1.name = "button1";     this.button1.size = new system.drawing.size(39, 34);     this.button1.tabindex = 10;     this.button1.usevisualstylebackcolor = true;     this.button1.image = properties.resources.close_project_img;

and when go [design] view, error :

to prevent possible data loss before loading designer, following errors must resolved:   projectitem unavailable.       instances of error (1)    1.   show call stack    @ envdte.projectitem.get_filecount() @ microsoft.visualstudio.design.serialization.resxglobalobjectprovider.getfilenameforprojectitem(projectitem item) @ microsoft.visualstudio.design.serialization.resxglobalobject.buildtype() @ microsoft.visualstudio.design.serialization.resxglobalobject.getobjecttype() @ microsoft.visualstudio.shell.design.globaltype.get_objecttype() @ microsoft.visualstudio.shell.design.globalobject.gethashcode() @ system.collections.generic.objectequalitycomparer`1.gethashcode(t obj) @ system.collections.generic.dictionary`2.findentry(tkey key) @ microsoft.visualstudio.shell.design.globalobjectservice.getglobalobjects(type basetype) @ microsoft.visualstudio.design.serialization.codedom.aggregatetyperesolutionservice.gettypefromglobalobjects(string name, boolean throwonerror, boolean ignorecase) @ microsoft.visualstudio.design.serialization.codedom.aggregatetyperesolutionservice.gettype(string name, boolean throwonerror, boolean ignorecase) @ microsoft.visualstudio.design.serialization.codedom.aggregatetyperesolutionservice.gettype(string name) @ system.componentmodel.design.serialization.designerserializationmanager.getruntimetype(string typename) @ system.componentmodel.design.serialization.designerserializationmanager.gettype(string typename) @ system.componentmodel.design.serialization.designerserializationmanager.system.componentmodel.design.serialization.idesignerserializationmanager.gettype(string typename) @ system.componentmodel.design.serialization.codedomserializerbase.deserializeexpression(idesignerserializationmanager manager, string name, codeexpression expression) @ system.componentmodel.design.serialization.codedomserializerbase.deserializepropertyreferenceexpression(idesignerserializationmanager manager, codepropertyreferenceexpression propertyreferenceex, boolean reporterror) @ system.componentmodel.design.serialization.codedomserializerbase.deserializeexpression(idesignerserializationmanager manager, string name, codeexpression expression) @ system.componentmodel.design.serialization.codedomserializerbase.deserializepropertyassignstatement(idesignerserializationmanager manager, codeassignstatement statement, codepropertyreferenceexpression propertyreferenceex, boolean reporterror) @ system.componentmodel.design.serialization.codedomserializerbase.deserializeassignstatement(idesignerserializationmanager manager, codeassignstatement statement) @ system.componentmodel.design.serialization.codedomserializerbase.deserializestatement(idesignerserializationmanager manager, codestatement statement)    error    not find associated topic error.

i can click "ignore , continue" , [design] view opens fine, button doesn't show image on view (it show in compiled program).

what doing wrong here?

you should not edit form.designer.cs directly because overwritten designer. designer runs code in form.designer.cs file when open designer. since code run vs2010, environment little diffrent

just test, try setting image property button_click event method instead, might image not found reason

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
